A clifffis a tall steep rock face. It is the result of sea waves erosion.
Soft rock, like sand and clay, erodes easily to create gently sloping cliffs.
Hard rock, like chalk, is more resistant and erodes slowly to create steep cliffs.
External Agent: sea.
External Process: erosion.

It is a landform created by running water, eroding sharply into soil, typically on a hillside.
Gullies resemble small valleys, but are metres to tens of metres in depth and width.

External Agent: running surface water.
External Process: erosion.

A waterfall is a place where water flows over a vertical drop in the course of a stream or river.

The vertical drop can be due to a fault, or to a gorge created by a river.

Water is an important eroder agent at the bottom of the waterfall, due to the strength of the falling water.

External Agent: running surface water.
External Process: erosion.
