How is limestone formed geography?
Limestone is a stratified rock, which means it was laid down in layers on the bed of a warm shallow sea. It was formed from skeletal remains (teeth, bones, shells) of marine creatures such as fish, sea urchins and corals and consisted almost entirely of calcium carbonate.
What is limestone erosion?
Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms. These include limestone pavements, pot holes, cenotes, caves and gorges. Such erosion landscapes are known as karsts. Coastal limestones are often eroded by organisms which bore into the rock by various means.
What are the 2 types of limestone?

What are 2 characteristics of limestone?
Limestone is usually gray, but it may also be white, yellow or brown. It is a soft rock and is easily scratched. It will effervesce readily in any common acid.
What causes a river to form a gorge?
A river can form a gorge by slowly eroding through layers of limestone and other soft rock layers, cutting a deep channel with steep sides. Wind, water and freeze-thaw erosion also helps to erode rock formations on each side to widen or steepen the walls of a gorge. How Large is a Gorge?
What kind of rock is Cheddar Gorge made of?
The amazing thing about Cheddar Gorge is that it was formed in the regular way that gorges are formed ( see Geography Cat’s article on this for more detail) and yet the rock is limestone.
Where does limestone come from and how is it formed?
Limestone is any rock that is made mostly from calcium carbonate, but there are several types. It forms with carbonate rocks were deposited in seawater and continue to form as coral reefs in shallow seas. Marine limestone comes together when seawater with high concentrations of chemicals as they dissolve.
How are gorges formed during the ice age?
These gorges have been attributed to the melting of glaciers at the end of the ice age. The water was released from the melting which resulted in a few very large flood events which were far larger than any previous seasonal flooding. The water moved over the surface and collected debris as it went.
