Q1: Which kinds of cliff are most dangerous to live on?

[Answer]

A cliff forms because the sea is cutting back into the land. Wherever you see a cliff you know that the cliff is wearing back.

But some cliffs wear back faster than others. Those that face directly into storm winds will wear back faster than those in the shelter; low cliffs will wear back faster than tall ones; and cliffs made of soft materials will wear back fastest of all.
