Sedimentary rock. Eg Rock salt.
Coves formed where rock runs in bands horizontal to the direction of the waves. There is a band of resistant rock closest to the sea and a band of less resistant rock inland. The wave seeks out faults in the hard rock and erodes through to the soft rock behind. Then the Wave eroded the softer rock faster and this leaves a circular cove with a narrow entrance where the sea enters.
because to main rock type is clay which is easly erroded by the sea therefor the cliff is undercutt and it falls down this happend again and again
River rock can be composed of any rock type, or any combination of rock types.
an igneous rock.
Chalk is a form of limestone, a sedimentary rock.
Rock salt is not a rock...its just a salt that can be extracted from salty water especially from sea water.
Limestone and chalk.
Sand is made up of crushed rock and sea-shells. The colour of the sand depends on what type of rock particles are in it.
rock salt
I think you are describing a type of limestone called coquina.
Sea floor bassalt and sediments.
The Rock of Gibraltar
Coves formed where rock runs in bands horizontal to the direction of the waves. There is a band of resistant rock closest to the sea and a band of less resistant rock inland. The wave seeks out faults in the hard rock and erodes through to the soft rock behind. Then the Wave eroded the softer rock faster and this leaves a circular cove with a narrow entrance where the sea enters.
The remains in question are the shells, as a source of calcium carbonate derived originally by the animal from solution in the sea-water..
A wet rock.
The Mediterranean Sea
Three examples of sedimentary rock are: Slate (compressed silt), Limestone (skeletal remains of minute sea creatures), and Sandstone (compressed grains of sand).
