What is mappleton cliffs made of?

MAppleton Cliffs, located on the East Yorkshire coast of England, are primarily composed of soft boulder clay and chalk. The boulder clay, a type of glacial till, is prone to erosion, which contributes to the cliffs' instability and frequent landslides. The chalk layers, while more resistant, still play a role in the overall geological structure of the cliffs. This combination of materials makes the area vulnerable to coastal erosion.
