* Sedimentary rocks:
* Sandstone: Formed from cemented sand grains, often found in coastal cliffs.
* Limestone: Formed from the skeletons of marine organisms, often creating dramatic cliffs with caves and arches.
* Conglomerate: A mixture of gravel and sand cemented together.
* Igneous rocks:
* Granite: A hard, resistant rock, often found in mountainous cliffs.
* Basalt: A volcanic rock, often forming dramatic cliffs with columns.
* Metamorphic rocks:
* Marble: Formed from limestone under heat and pressure, often with a beautiful, swirling pattern.
* Slate: Formed from shale, often creating smooth, layered cliffs.
The type of rock a cliff is made of depends on the geological history of the area and the processes that formed the cliffs.
