The rocks of a cliff could be of any rock type.
igneous
its a hard to explain but ill do what i can... so... how quickly the cliff erodes depends on 3 things the type of rock its made of, how long its fetch is and the steepness of the cliff. The type of rock has a huge impact on the speed of the cliff getting eroded because if its made of resistant rock then there are less joints therefor its strong but non-resistant rock is not able to defend itself from hydrolic action, abrosion, attrition and solution...the four types of erosion.
A rock star?
When a wave impacts a cliff face, air is forced into cracks under high pressure, widening them. Over long periods of time, the growing cracks destabilise the cliff and fragments of rock break off of it
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

A cliff can be made up of nearly any kind of rock From calcium to granite to sandstone.
The 'white Cliffs of Dover" are made of chalk and a little crumbly.

sandstone
They're made of limestone (chalk).
Chalk.
Sand Stone, at least that's what I think, because this website says that it was carved out of a Sandstone Cliff.
sedimentary rock is a multiple of layers
A rock at the edge of a cliff has potential energy. This energy may be converted to kinetic energy by the force of gravity if it falls off the cliff.
it is a magma type
That's not a chemical. We call that "gravity."
the type of rock made mostly from clay is the shale rock
