Why do caves form in only certain types of rocks?
Caves typically form in rocks that are soluble in water, such as limestone and gypsum. These rocks can be dissolved by carbonic acid in rainwater, creating cavities over time. So, caves are more likely to form in rocks that are easily eroded by water.
What rock is eroded to form caves?
Mainly limestone.
Two most common types of rock in which sea caves form?
The two most common types of rock in which sea caves form are limestone and sandstone. This is because these types of rock are more susceptible to erosion by the action of waves and coastal processes, creating caves and other coastal formations over time.
What environmental process forms the dry caves?
The only caves that can form dry are; Rock-shelters eroded out by wind-blown sand. Talus Caves: voids between landslipped boulders and their parentrock-face. Mass-movement fissures: formed by a type of landslip. Lava Tubes - rather stretching the point because they result from molten lava flowing out from beneath a solidified crust. Caves formed in limestone - as most caves are - arekarst features, i.e. result from dissolution of the rock by weakly-acidic ground-water. Although such caves can subsequently lose their formative streams and so become dry, they were not formed dry and do not develop any further.
What are Erosional landforms formed by groundwater?
caves

What rock is eroded to form caves?
Mainly limestone.
What materials make up most caves?
Air! :-) A cave is a natural void in rock, and the rock in which thevast majority of the world's caves form is limestone.
When rain soaks aways rock below the ground to form caves are called?
Right - rain absorns atmospheric CO2 to become slightly acid. When this water percolates through discontinuities in limestone, the rock is dissolved by this carbonic acid (an example of chemical weathering), and over time the conduits this creates enlarge and coalesce to form caves.
What type of deposit form limestone caves?
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.
What kind of rock would you probably find in a cave?
You would likely find sedimentary rock in caves, as it is common for caves to form in limestone, dolomite, or sandstone due to the processes of erosion and underground water flow. Igneous and metamorphic rocks are less common in caves, but can also be present in certain geological settings.
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 main rock dissolves to form caves?
Limestone and its metamorphic form, marble - calcium carbonate is the rock's principal constituent mineral and it is this that dissolves.
How did the caves in US form?
Almost all caves were formed by the actions of water. It dissolves the rock and and forms the caverns and spectacular views.
What are most caves made out of?
Most caves are made out of limestone, which is a sedimentary rock composed of calcium carbonate. This rock is easily dissolved by acidic water, leading to the formation of caves through a process called chemical weathering and erosion. Other types of caves can also form in volcanic or igneous rock, such as lava tubes.
When rain soaks away rock below the ground to form caves what has occurred?
mechanical weathering +++ I'd class it as chemical weathering because the action is dissolution by weakly-acid, and it works only in limestone, gypsum and dolomite - although dolomite deposits are not normally structurally disposed to cave development.
What type of rock is made in caves?
Only deposits: sediments and calcite. A cave represents removal of rock, not its making.
