Rain water percolates into ground. It contains carbon bi oxide. After dissolution in the water it forms carbonic acid. It dissolves lime stones. Calcium carbonate of the lime stone gets converted into calcium bicarbonate. This is soluble salt. It gets reconverted into insoluble calcium carbonate. Very beautiful caves have been formed in south America and else where. They has got those beautiful stalactites and stalagmites. It took millions of years to form these caves.

caverns
An oil well is usually drilled into underground rock formations, specifically into geological structures that contain oil reserves. These formations are typically sedimentary rocks, such as sandstone or limestone, which have trapped and preserved oil over millions of years. The drilling process allows for the extraction of crude oil from these reservoirs.
yes i guss
it first forms by someone taking the stone and rubbing it on the ground lol
yes
You can find limestone anywhere under the ground.
Ground water I think you meant! It is slightly acidic, primarily from dissolved atmospheric CO2, so can dissolve limestone given enough time.
By digging with a spoon.
limestone and sandstone are found under ground and oil is there to
when acidic ground water comes in contact with rock that contains calcium carbonate the acidic water starts to dissolve the rock
Rain water sinking into limestone bedrock will slowly dissolve the limestone and, over many centuries, form potholes and caverns. In time, the cavern's ceiling will become too thin to support the ground above. A sink hole will appear when the cavern's roof collaspes.
They are formed by the limestone being dissolved by ground-water seeping through the limestone's joints and other fissures.
No, it can't. Limestone melts only at high temperatures. But carbonic acid can, over the course of time, attack and dissolve a lot of limestone. Here's the deal, and it's on the mark. The atmosphere contains mostly nitrogen and oxygen as you know, but there's a bit of darbon dioxide in there, too. And water in the air picks up CO2 and becomes carbonic acid. This is carried to earth in rain. This doesn't "affect" rain all that much, but it does lower the pH of rain a bit. And the carbonic acid, though it is weak, will seep into the ground where limestone layers form an under layer and slowly, over the course of geologic time, dissolve the limestone to create some fantastic caves!
