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.
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.
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.
Caves can be found all over the world, typically in areas with limestone or volcanic rock formations. They can be found in deserts, mountains, coastlines, and even in urban areas. Many caves are popular tourist destinations for their unique geological features.
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.
Natural caves and rock shelters can be found in various landscapes and geological formations. They can be found in mountains, hills, canyons, coastal cliffs, and even underground. Additionally, they are often found in areas with sedimentary rock formations that are susceptible to erosion processes such as caves formed from limestone, sandstone, granite, and volcanic rock.
It depends on the cave. Since many caves are limestone (water carves it nicely), you usually find limestone. But granite is common in New Hampshire & Vermont.

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.

Limestone caves are found all over the world, with notable examples in places like Carlsbad Caverns in the United States, the Jenolan Caves in Australia, and the Caves of Aggtelek Karst in Hungary. They are formed by the dissolution of limestone rock by acidic groundwater over thousands of years.
The Burren in Ireland is primarily composed of karst landscape made up of limestone rock. This unique geological formation includes limestone pavements, caves, and grykes, which are deep fissures between the rocks.

Additionally, they are often found in areas with sedimentary rock formations that are susceptible to erosion processes such as caves formed from limestone, sandstone, granite, and volcanic rock.
Underground limestone caves form through the chemical weathering of limestone rock by water that is slightly acidic. Over time, this process dissolves the rock and creates caverns and passageways underground. Factors such as the presence of cracks and fissures in the limestone, as well as the flow of water, contribute to the formation of these caves.
