Why many caves are found in limestone rock?
Most caves are in limestone. Limestone is a sedimentary rock laid down in beds and fractured into joints by tectonic processes. These discontinuities allow water to pass, initially extremely slowly, through the rock mass from catchment to spring. Further, and crucially, limestone is slightly soluble in rain-water, so over time the water gradually dissolves out conduits that become cave passages. The whole process is far more complex that that, with many local variables, but the foregoing is the gist of it.
Why are limestone caves so common?
Because limestone uplands with appropriate internal geology and surface drainage in areas of long-term, suitable climatic conditions are so widespread. Not all limestone areas support caves though.
What type of rock are found in caves?
It's more accurate to ask what types of rock hold caves, given that a cave is a lack of rock, as i think that's what you mean! Most caves form in limestone, so the floor, walls and roof are of limestone, as are most of the boulders on the floor. Rivers can also wash in cobbles of other rock, such as Millstone grit from above the Limestone in Carboniferous formations. Lava tubes form in low-viscosity lava flows, so are in basalt or similar low-Si rock. You can also find minor caves and rock-shelters formed in other competent rocks by fluvial or sub-aeriel weathering. E,g, sea-caves, and cavities sand-blasted into sandstone rock-faces by desert sand-storms.
Why are there so many caves in the limestone rock?
It is all thanks to the rock's solubitlity in water, but cave development in any give limestone region is also controlled by the specific geology, hydrology, geomorphology and continued precipitation over 10s or 100s of 1000s of years.
How many caves are there in the Philippines?
There are thousands of caves in the Philippines, with around 400 caves documented and explored so far. The limestone karst landscape of the country provides ideal conditions for cave formation and exploration.

Why are there so many caves in southern Indiana?
There are so many caves in Southern Indiana because of how much limestone there is undernealth the dirt, once moisture gets undernealth the dirt and into the limestone, it creates a small hollow hole, then slowley starts to increase in size when more water gets to the limestone.

Why do you find so many underground features in limestone?
Limestone is a rock that is easily dissolved by water, forming cavities and underground features like caves, sinkholes, and underground rivers. Over time, the natural processes of erosion and chemical weathering create these unique geological formations in limestone terrain.
Caves are formed by?
Most caves are in Limestone, and develop by ground-water dissolving the rock as it percolates through the rock's joints & other discontinuities. The water is rendered acid so it can dissolve the calcium carbonate by absorbed atmospheric CO2 (becoming Carbonic Acid).

How is carbonic acid responsible for the for the formation of some caves?
Over time it dissolves limestone or gypsum, so most caves are in those rocks, of which limestone is by far the more widespread.
How were waitomo caves formed?
The Waitomo Caves in New Zealand were formed over millions of years through a combination of underground water flow and the dissolving of limestone rock. As acidic water trickled through the limestone, it created a network of underground tunnels and caverns, eventually forming the intricate caves and spectacular stalactites and stalagmites that we see today.
Where do you get a rock type Pokemon?
Usually you can find it in caves. Most of them are. So just look in caves. If you need a rock type Pokemon look in caves!! So I hope this helped you!
What is inside of a cave?
Inside a cave is, hopefully, air so you can study the cave. But many are filled with water, and most have some liquid since this forms the majority of limestone and other soft rock caves. Lava caves are different but also may be formed by ground water. Inside caves, you may find rock formations: stalactites from the ceiling and stalagmites from the floor, formed over thousands of years by minerals in dripping water. In shallow caves, you may find animals such as bats, bears, snakes, and rodents. Sometimes caves become the home for flocks of birds. ++++ That second paragraph is rather vague. Many cave passages are indeed filled with water, and caves in limestone, rock-salt and gypsum are formed by water dissolving the rock's primary mineral (the rock's chemistry is important, its hardness, less so), but over time caves can lose their formative streams completely. A few limestone caves form by dissolution by highly-acidic, mineral-rich water circulating from below; but these are very unusual. Most use rain and snow-melt water from the land surface. ' Lava caves differ completely: they form in basalt lava flows by molten rock draining from below the solidified surface - nothing to do with ground water.
