An extrusive igneous rock.
Shale
The 'Rock scene" refers to the venues of an area where rock music is presented to the public. It is basically the Clubs, bars, arenas in your area where you can go listen to rock music. That is the Rock Scene for your area.
intrusive igneous rock
a Obsidion rock
When rock above a cave collapses, a sinkhole is formed.
When rock above a cave collapses, a sinkhole is formed.
It is called weathering.
When a volcanic cone collapses it forms a caldera.
Rainwater containging carbon Dioxide dissolves underground rock
such a rock may be of Gypsum (Magnesium sulphate) or common salt (sodium chloride ).
When the rock of a cave collapses, it forms a feature known as a "sinkhole" or "cave-in." This occurs when the ceiling of the cave becomes unstable due to erosion, water infiltration, or structural weaknesses, resulting in the sudden dropping of rock and debris. The collapse can create an opening at the surface, potentially impacting the landscape above and causing hazards for structures nearby. Additionally, this process can lead to the formation of new geological features over time.
Almost all caves were formed by the actions of water. It dissolves the rock and and forms the caverns and spectacular views.
Crushed salt dissolves faster in cold water compared to rock salt. This is because crushed salt has a larger surface area for water molecules to come in contact with, facilitating faster dissolution. Rock salt, on the other hand, has a smaller surface area which slows down the dissolution process.
It is called weathering.
parent rock
Carbonic acid dissolves limestone by turning the mostly insoluble calcium carbonate into soluble calcium bicarbonate. The dissolution hollows out areas the the rock, creating caves. When one of these caves collapses a sinkhole will form above.
