They don't!

Deposits don't form caves, but limestone is a sedimentary rock formed from marine or lacustrine deposits.

Caves form within limestone by dissolution of its calcium carbonate by ground-water flowing through the rock's joints, bedding-planes and faults.

In what type of rocks do caves form?

Caves usually and mostly forms in sedimentary rocks. Example, Limestone.


What type of sedimentary rock made up many caves in the eastern US?

Limestone is the type of sedimentary rock that makes up many caves in the eastern US. These caves form when groundwater dissolves the limestone, creating underground voids and caverns.


Why do caves only form a certain type of rock?

Caves are formed by rainwater dissolving away limestone or sandstone.


Why are there so many caves in limestone rock?

Limestone is a type of rock that is easily eroded by water, which can create caves over time. Water dissolves the limestone rock to form caves through a process known as chemical weathering. Additionally, limestone can also be carved out by underground rivers or other natural forces, resulting in the formation of caves.


What rock is a deposit of organic limestone on land?

The rock that is a deposit of organic limestone on land is called travertine. Travertine is formed from the precipitation of calcium carbonate minerals from spring waters, making it a type of limestone that is often found in caves and around hot springs.


Why most caves form by limestone?

Limestone is susceptible to dissolution by acidic water, which is common in most natural environments. Over time, this dissolution process carves out cavities underground, leading to the formation of caves. Additionally, limestone is a common and widespread rock type, which contributes to the prevalence of limestone caves.


What type of limestone is often found in caves?

I think I know what you mean.The vast majority of the world's caves are formed in limestone by water dissolving the calcium carbonate that is the rock's main constituent. As for "type", well, almost any "type" by age or source of limestone physically capable of supporting itself above the developing void. Caves will also form in marble (metamorphosed limestone) and in gypsum (calcium sulphate), in the same way.So the limestone is not "often found in caves" - except as boulders that fallen from the roof, or re-precipitated as calcite stalactites etc - but is literally all around almost all caves!More to the point perhaps is the combination of factors that encourage or discourage caves to form in a given limestone area, and that is far more complex.


What type of rock is mostly associated with caves?

Limestone.


What type of rock is usually present in areas with a lot of caves?

Limestone is the type of rock that is commonly found in areas with a lot of caves. Limestone is made of calcium carbonate, which is soluble in water. Over time, as rainwater seeps into the ground, it dissolves the limestone and creates openings and caves in the rock.


What type of caves are in the Appalachian plateau?

Karst caves (i.e. dissolutional features in limestone).


What type of rock is usually present in area with a lot of caves?

Limestone is the most common type of rock present in areas with a lot of caves. This is because limestone is easily dissolved by acidic groundwater, forming caves through a process known as karstification.


Where did you probably find a deposit of limestone what type of setting did it form in?

Limestone is formed on the floor of ancient seas from the skeletal remains of marine organisms such as coral, forams and molluscs, etc.
