Chalk is more resistant than clay because of its porous structure.

Answer:

Clay is less resistant than chalk so it is eroded faster, leaving chalk sticking out to form escarpments and wide flat areas where the clay was eroded called vales. Escarpments have steep scarp slopes on one side, and gentle dip slopes on the other.
