headlands
Those are called rock formations or protrusions, such as spires or pinnacles. They are created by erosion and weathering processes that shape the cliff face over time.
the hard kind
Headlands are finger-shaped projections that form when cliffs of hard rock erode more slowly than surrounding softer rock does.
The material the cliffs are made from is CHALK
rock
It depends on what kind of rock they are made of. Cliffs formed of igneous rock generally do not contain carbonates. Cliffs that have some limestone, marble, or dolomite do contain carbonates.
A hard coastline is characterized by steep cliffs, rocky shores, and minimal to no sediment accumulation. It is typically formed by the erosive forces of waves and is less susceptible to erosion compared to soft coastlines. Examples of hard coastlines include areas with sea cliffs or volcanic rock formations.
There is no cheese on the moon, it is jut an airless ball of rock in space.
The cliffs and canyons of Starved Rock are made of an Ordivician age sandstone called St. Peter sandstone.
Sea cliffs: High vertical cliffs formed by the erosion caused by waves hitting the coastline. Sea caves: Caves formed by wave action eroding the rock along the coastline. Headlands: High points of land that jut out into the sea, formed by differential erosion from wave action. Sea stacks: Isolated columns or pillars of rock that are left standing in the sea after the collapse of a headland. Wave-cut platforms: Flat areas at the base of sea cliffs formed by wave erosion and deposition of eroded material.
you may not know this but sea cliffs are made by rock and many other minerals
The white cliffs of Dover are composed of chalk.
