limestone
Limestone with a pure white color normally formed in clear, warm water. It could also have formed in a river estuary as well as river beds.
they are both rocks but both formed different ways chalk is formed by dead sea creatures skeleltons build up to form chalk and limestone is formed by shells and very littke amounts of mud and sand

A cave?
Carbon dioxide mixes with groundwater making a weak acid that can only dissolve limestone. As it travels through limestones natural cracks and pores it enlarges them until an opening is formed called a cave
cement is formed from limestone by combustion of limestone ( heating of the limestone)!
concrete is formed from limestone by the combustion of the limestone (heating of the limestone)!
limestone pavement is formed by leaving exposed limestone for ages
Limestone and limestone formations.
Marble is formed when limestone is metamorphosed.
The limestone caverns themselves are formed by groundwater gradually dissolving the limestone rock. In this process, some of the limestone is taken into solution, and under favourable conditions, it will form a drip on the roof of a cavern. This may eventually build to form a stalactite above, and perhaps also a stalagmite below it.

Yes, Marble is formed from Limestone, but not Slate.
1 Running water on the surface of the earth erodes the land. Groundwater also can cause erosion under the surface. As water flows through the soil, acid is formed. This acid can cause minerals to be dissolved.2 Minerals that are carried in groundwater can also be deposited in other places. This cycle of erosion and deposition can cause underground caves to form. This happens especially in areas where there is limestone below the surface.3 A cave is an underground opening. It has a connection to the surface of the earth. A cave is formed by the erosion of limestone under the ground. The acid water moves through the cracks in the limestone and makes them larger.
