. Lots of Animals live in caves like: bears, wolves, bats, dung-beetles, glow worms, grasshopers, spiders, worms, and (if there is water) fish
. There are lots of types of caves like Solution Caves, Primary Caves and Lava Tubes, Sea Caves, Glacier Caves or Ice Caves, and Other types like Fracture, Talus, and Anchihalne Caves
. Some caves (even today) are used for aging wine and chesse preservations
. Limestone is ussualy white but can be brown yellow or red from iron oxide, or carbon which makes it blue, black, or grey
. Bedford, Indiana was once listed as the Limestone capital of the world
. The Washington Monument was mostly made up of Limestone from Bedford

What I learned

-The glowworm catchs food by using silk largly made up of mucus to catch food by leaving the strands hanging the silk is extremely sticky and catchs the bugs who fly through it The glowworm got its name by the back of its tail it glows blue attracting insects when the insects are stuck the glowworm eats the silk and slowy brings up the insect stuck to the silk and eats it.

-The caves on our planet are the least explored place on earth.

-The caves can come in many different forms and places such as volcanic caves, ice caves , Glacier caves and many more.

-One of the many ways caves form is when water gets underground
the water then absorbs carbon dioxide and becomes a acid after nillions of years the acid eats awy at the stone making caves and caverns.

-Limestone caves can be many different colors including blue, black, grey, red ,brown and yellow.

-Many creatures have been discovered in limestone caves that dont live anywhere else in the world.

- Limestone Caves in Mexico are over 400 metres deep and some big enough to absorb the empire state building.

-Many underground cave are underwater.

-In mexico people used to beleive that every year the soul of a young girl because some type of shrimp glows red and the locals beleived it was blood.

You need to make a connection between limestone and caves.

Liam said...

Caves and limestone, they work together to create stunning scenes and unknown creatures. I'll talk about limestone first. Limestone covers nearly ten percent of the Earth's surface. Limestone is made up of different minerals, which are made up of things like shells and and various corals. For shells and coral to form together into rock, limestone must be formed underwater. Limestone can also be found all over the world: in the USA, Vietnam, and Borneo. In a lot of places, you will find the limestone in unique shapes and formed by rain or water levels. From deathly sharp spikes to cliffs and jagged mountains, limestone continues to create un-forgetable scenery. Not only that, but limestone is the foundation for most of the worlds most amazing caves!

Now caves on the other hand are the foundation for unusual forms of life. Many caves, as expected, have bats, spiders, worms, and other creepy critters. What you might not know is that some animals can only live in that type of environment due to light and temperatures. If you think about it, not all caves are pitch black, some are just "dents or ruts" in the side of hills and mountains, that is where you'll find animals like cougars, bears and other mammals. As you can see, caves and limestone have needed each other since the beginning of time. And my guess is that they will be for the remainder of time too!

-Caves are sometimes known as earths final frontier with countless miles of caves in the earth I guess that fact is understandable.
-A cave discovered 2 years ago by humans (existed for around 1, 000, 000) is deep anough to completley shelter the empire state building.
-Humans were not the first ones to discover caves, they first were discovered by some of the strangest animals on the planet some od those animals are: bears, wolves, bats, glow worms, grass hopers and if there is water contained in the cave ( underwater caves) there tends to be different kinds of fish.
-Glow worms live in caves hanging on stalactites weaving sticky strands of silk that hang from the stalactites in the worms underside there is a chemical reaction that causing the bootom of the worm to light up causing bugs to enter in search of warmth and light, the bugs will then get caught in the strands and are officially toast!

-10% of the earths surface is lime stone.
-Limestone can be many different colors, they are usualy white but can also be brown, yellow or red ( that is from iron oxide) carbon makes it blue black or grey.
-Water eats away atlimestone causing it to become sharp but when limestone is under water the limestone will erode when water runs along limestone it collects some of the minerals and it combines with carbon dioxide and becomes a acidic which eats away at rocks creating many different caverns.

Limestone is what covers about 10% of the earth. It is also what most caves are made of. Without it there would not be a lot of caves. There are many uses for limestone like: sculpting, medicines, added to bread and cereals for more calcium. Limestone has also been used to make a structure that we all know very well- The Ancient Pyramid of Giza! There are lots of types of limestone, here are some: Algonquin Limestone, Eramosa Limestone, Hope Bay Limestone, Mara Limestone and Senesun Limestone. These types of limestone are all found in Canada. Limestone is made from minerals from the sea, so even if you sea limestone standing thousands of feet above water, it was once under water. Humans need limestone so let’s hope that we don’t waste it all.

Caves are deep, dark and full of things that we don't want to discuss. They are full of very interesting creatures that all learn to survive like the Gray bat, Tooth cave spider and if there is water cave fish and the Olm- those are only few. There are lots of types of caves like Solutional caves which are the most common of caves are mostly made out of limestone, Primary caves- caves that are formed at the same time as the surrounding rocks, Glacier caves (sometime known as Ice caves) are formed in ice and under glaciers. There are many more types of caves. Caves are the least explored places on the earth and some are even under water! Caves are fascinating yet, very creepy to me and I hope that we can explore them some more. How knows? We might even find some new life!

Where in the WorldThe cave in this video is The Cave of Swallow in San Luis Potosi, Mexico.
-The Cave of Swallows is the deepest cave in the world. It is big enough to hold the Empire State building in New York City.
Caves or the least explored places on the world.
Humans where not the firt to be inside caves.
There are many strang animals in the world including:glow worms, bats, dung-bettles, spiders, salamanders, newts, some lizards, and many, many bugs.
- Most caves form in karst, which is a type of landscape made up of either limestone, dolomite, and gypsum rocks.

-Most of the worlds caves are limestone.
-Limestone takes up 10% of the worlds surface.
-Limestone is made out of shells that break apart to form almost sand which gets compressed over time and turns into limestone.
-Limestone is formed under water.
-Many limestone caves of today used to be the bases of coral reefs.
- The rain water eats away at the limestone. The water then turns into rivers running through the caves.
-When a limestone river finds its way under the cave it erodes the bottom of the cave which makes it move very slowly.

Taylor when you said that thing about Limestone Caves in Mexico you should be carefull because it isn't MOST of the caves in Mexico it is ONLY The Cave of Swallows in San Luis Potosi, Mexico because it is the deepest cave in the world.

Good point Shaylen!

what i learned about CAVES:

- caves are home to many animals that would not survive in the "outside world"

- caves are home to animals such as, bats, roaches, very big centipedes, glow worms, many different species of spiders some times fish and so many more.

- caves can be so big that you can fly a jumbo jet through them.

- there is a cave in the U.S I believe that is so deep that the Empire State Building would be able to be theoretically fit inside the giant cave.

-there are many kinds of caves.

- water ways in caves can be formed by chemicals in the flowing water that eat at the cave floor.

-caves are the least explored areas on earth.

things i learned about LIMESTONE:

- limestone is often white, but has many execptions due to the quantity of chemicals in the stone.

- Limestone is made of underwater solids like coral and empty shells.

- most super big caves are made of mostly limestone.

- limestone, water and other natural things create these wonderful and most of the time huge caves. :) 0_o

corection, while i was looking on a unlabled world map i misplaced Mexico, the cave of swallows in Mexico is big enough to thoeretically fit the Empire State Building

Ingrid said...

That video was absolutely breathtaking. I really like the cave called The cave of Swallows that was located in San Luis Potosí, Mexico. I will talk about limestone, then caves.
Limestone is a very popular sedimentary rock that covers 10 percent of the world's surface. Limestone is mostly made out of calcite, but as well as other minerals and shells and small marine organisms. Limestone is very common in architecture and is found in many monuments,especially in North America and Europe. Two large sources of limestone are Bedford, Indiana or also Lawrence County, Indiana. Limestone dissolves in water easier than any other rock. Rainwater picks up a small amount of carbon dioxide while falling, this produces a very weak acid. Calcite is vulnerable to this acid, and after the acid eats away at the limestone, caves were made. Limestone can be red, brown, yellow(from iron oxide, grey, black or blue.
There are many different types of caves, like sea caves, lava tubes, primary caves, erosional caves, glacier caves and many more. The cave of swallows is 400 meters tall and is big enough to shelter the empire state building, this is the biggest cave shaft in the world and was only discovered
two years ago. Caves are still the least explored natural beauty in the world. There are many animals that live the like bears, wolves, bats, glow worms and if a sea cave, many different types of fish. The only thing making caves possible is limestone, they have relied on each other for as long as anybody could know.

Caves and limestone, how are they connected you may ask. Well, I'll explain that later but first I'll talk about each individually.
Limestone is a rock composed of minerals made up of shells and coral. For the marine materails to transform into rock they must be underwater. Limestone covers 10% of the earth's surface and can look quite different depending if it has been affected by erosion. The rain can erode limestone creating clifts,and sharp, jagged spikes comming up from the earth. The erosion of limestone is essentially what creates most limestone caves.
Most caves on earth are made of limestone. The largest cave shaft in the world is composed of limestone. It is the Cave of Swallos in Mexico. It is 400m deep, that's enought space to fit the Empire State Building. Caves can not only be huge, but can help sustain life for some very interesting creatures. These creatures include bats, spiders, glow worms, and many other species of bugs. Sometimes you can find fish in the bottom of a cave if there is a source of water. Not all caves are pitch black even on the sunniest day of the year. These types of caves are the ones you expect to see bears in, hibernating during the winter.
As I have told you most caves in the world are made of limestone. These are some of the most interesting of caves too. So if there was no limestone there would be less places on earth to explore and wonder about. If there were no caves, the oh-so mystical creatures that lie within them would be lost. Although limestone would surely find another intersting masterpeice to be molded into, but would it be as interesting or mysterious as the CAVES the rock has given us today?

W.I.T.W. - Caves and Limestone

-Caves are the least explored place in the world

-The Cave of Swallows in Mexico is about 400 m. deep, large enough to fit the Empire State Building in it making it the largest cave shaft in the world
-Was discovered 2 years before the first man set foot on the moon

-Caves can support many different creatures such as land mammals like bears and wolves, or insects like millipedes and leather backs (look like a really big mosquito).
-It is very dark in most caves but some animals have adapted to take advantage of this like...

-The worm makes long silk strands covered in mucus that come from special glands in the worm's mouth
-Each worm can make dozens of these strands
-The Glow-worm’s tail glows an eerie blue light that comes from a chemical reaction inside a special capsule in the worm's tail hence the name "Glow-worm"
-This light acts as a lure for unsuspecting bugs that are attracted to light like the moth
-When the worm is done making the silk it waits in a mucus hammock of its own making and waits until a bug gets caught in the silk
-A whole group of these waiting worms almost looks like a starry night sky
-Once an insect in caught in the sticky silk, it can't get away, the worm then has to reel in the line and eat its catch ALIVE!

-Most caves are made in limestone
-Limestone covers 10% of the earth's surface
-Limestone is made up of minerals that come from marine shells and corals; therefore limestone is made under water
-Water that makes its way into underground caves is usually filled with carbon dioxide from the soil and eats away at limestone carving passages and pits out of the hard rock

The final frontier, where only the most adventurous dare to go While they are the least explored natural wonder of the world, they are one of the most amzing creations this world has to offer im talking about..........

.The Cave Of Swallows, in Mexico is 400 meters deep and lage enough to theoretically fit the Empire State Building.
.Caves house some of the strangest and facinating animals and insects in the world.These animals have had to adapt the darkness of the underground caves and even use it to thier advantage. One of these animals is the.......

.They create silk strands from glands in their mouths.
.These strands are filled with sticky mucus.
.They use these strands to atract prey.
.They also use a light at their tail.It glows blue because of a chemical reaction.
.Once the bug is trapped there is no escape.The strand is so sticky you cannot free yourself.
What makes these caves possible?........

.Limestone covers 10% of the Earth's surface.
.Most caves are made of limestone.
.Limestone is made up of minerals from coral and shells.
.Limestone caves are formed underwater.
And now, how do caves get their groves?........

.When water reaches more limestone it becomes erosive.
.On the way down it gathers carbon dioxide from the soil and becomes slightly acisidic.
.Over years this acid wears away at the limestone and creates winding passageways.

Caves was a most interesting WITW subject and I really learned a lot. Thank you Mrs.O'Hara!

-the cave of swallows in Mexico is 400 meters deep which is big enough o fit the empire state building inside
-caves are the least explored places on earth
-there are many different types of caves like glacier caves, volcanic caves, underwater caves and limestone caves (caves can be made entirely from limestone

-limestone covers 10% of the earth's surface
-limestone is made up of minerals and the fossils of marine animals(so all limestone had to be underwater at one point)

How water effects caves
-water that passes near limestone caves absorbs CO2 and becomes more acidic overtime, then when it gets to the caves, it erodes the caves making new passages and caverns
-some water builds the cave because the water absorbs limestone while eroding it and limestone contains a chemical called calcite then when the water drops from the ceiling it leaves behind calcite that builds up to form a stalactite
- the water that drops from the stalactite still has calcite remaining in it and it leaves calcite behind when it hits the ground and that calcite builds up to form a stalagmite
-columns are formed when a stalagmite and a stalactite build up against each other
- caves that once had growing caves will stop growing if they get flooded because the calcite in the water can't dry
-snotides(i don't actually know if that's what they're called) are formed from water that is contaminated with bacteria from sulfuric acid, this bacteria multiplies and hangs down from the ceiling of certain caves

other facts
a cave in the U.S.A was eroded by sulfuric gas in the air and now the gypsum(a mineral in limestone) formed crystals and now almost all of the walls are covered with crystals

-A natural shelter, an underground passage, a geological formation,vastly unexplored, a place where only the most adventurous dare to go - CAVES.


-The Cave of Swallows in San Luis Potosi, Mexico is the largest known cave shaft in the world.

-Caves are vastly unexplored. Before man could set foot into caves, some of the strangest and least known creatures in the world have made these dark spaces their home. Some creatures like the glow worm use the darkness of the caves to their advantage. They form sticky silk threads with their mucus. The light in their tails caused by a chemical reaction lures their prey. Insects are drawn to the light and get trapped in the sticky threads.


-Limestone covers 10% of the earth’s surface. It is a sedimentary rock where most caves are formed. Limestone is composed of minerals from marine organisms.

-Limestone dissolves under the action of rainwater. Rainwater has amazing effects underground. Rivers that run over limestone often seem to disappear. On its journey underground the water collects carbon dioxide making it acidic. This natural acid in the water slowly erodes and dissolves some of the limestone creating limestone caves. These are the most common type of caves and are called solutional caves.

Caves are the least explored place on earth. I wonder why, because I love looking around to find caves that I could explore. There is countless kilometers of caves depending on what you call a cave. In most caves humans are seldom first to find a cave. Caves are made possible by limestone, as most caves are made of this substance the world would really have a lot less caves than we do mow if there was no limestone. Some of the strangest and least known animals in the world call caves home, like the Cave glowworm, spiders, dung beetles, bats and much more. Caves are important because they give these animals a home and a place to store wine and cheese.
Cave Glowworm
If you were going down into a cave were this species live you would see something that looks like a galaxy on the ceiling. Though this is not natural light, this light is made by living organisms. Silken strand lowered from the ceiling are beautiful but have a sinister purpose, as there goal is to trap insects. There are hundreds of strands in the cave depending on how big the cave is. This animal catches prey by going fishing with a line of silk. The silk that the Cave Glowworm uses comes from a gland in its mouth and the silk is loaded with drops of mucus. Each worm makes about a dozen strings using the silk I described above. When it has finished making its fishing lines that hang off the ceiling the glowworm waits in a mucus hammock. If things were left to chance it would take the glowworm much longer to get the same amount of insects that this species does. But the Cave Glowworm does not leave things to chance, a ghostly blue light the result of a chemical reaction in its tail attract prey like flies. Insects seem drawn to the lights and when those insects get to close to the lights they get stuck in the silk. Once the insect The prey can not escape these sticky vines. Then the glowworm reels in the line and eats the insect. This species of glowworm ensnares its prey at the prey’s breeding site. Because of this, this species of glowworm have solved the most difficult challenge that cave dwellers face -finding a regular and reliant source of food.
Cave of Swallow
The Cave of Swallow in San Luis Potosi is 400 hundred meters to the bottom, deep enough that the Empire State building could fit comfortably in this cave. This is the deepest cave shaft in the world. People first explored this area two year before man first was on the moon.
Did you know most caves are limestone? Well they are. Limestone is composed of marine shells and cochins. Over 10% of the world is covered in limestone. In some places rain has sharpened limestone to pinnacles that not surprisingly are very sharp. Rain can do a lot worse to limestone. Some rivers that flow over limestone seem to completely disappear. When water goes under ground it obtains a more erosive feature. As during its time overland the water absorbed carbon dioxide, making the water slightly acidic. This acid eats away at the limestone and after millions of years water creates a maze of passages.

Lots of unfamiliar species live in caves and live quite differently from other animals that are more popular such as the bear or deer.

Many, many people explore caves for various reasons that many might not have thought of like exploring for artifacts or just for the fun of exploring and adventure.

Caves can be found in various places. Some are found in cliffs at the edge of the coastline, chipped away by the relentless pounding of waves. Others form where a lava tube's outer surface cools and hardens and the inside of the molten rock drains away. Caves even form in glaciers where meltwater carves tunnels at the beginning of its journey to the sea.

The greatest and longest cave system in the world is at Mammoth Cave Park in Kentucky, USA. It has about 591 kilometers (367 miles) of cave system. The deepest cave is the Voronya Cave in Abkhazia, Georgia with a depth of 2,191 meters. This is the difference in elevation from highest entrance to its lowest point.
The largest cave in the world is the Sarawak Chamber in Sarawak, Malaysia. Its floor area is 210,000sq.


Limestone is a sedimentary rock that's primary ingredient is calcium carbonate.

Limestone ordinarily is white, but can appear in different colors and patterns due to impurities. Impurities of iron oxide give the rock brown, yellow or red color. Impurities of carbon can give it a blue, black or gray color.


Caves can be built up with limestone rock.
