They are often created by erosional processes within intermittent streams.

Building the coastline at a rate greater than sea level rise and depositing sediment faster than erosional processes can remove it.

The erosional process is most readily seen at Niagara Falls, where the river has quickened the process.

A scarp may be formed by tectonic, erosional, or depositional processes.

This erosional process softens and rounds the features of the crater.

Today, since the climate is more arid, these erosional processes are significantly slowed.

Most sea-cave walls are irregular and chunky, reflecting an erosional process where the rock is fractured piece by piece.

In geology, degradation refers to the lowering of a fluvial surface, such as a stream bed or floodplain, through erosional processes.

"Formation" is also used informally to describe the sometimes odd shapes (forms) that rocks acquire through erosional or depositional processes.

Studies show that the quarrying of the lee side is a much more significant erosional process than the abrasion of the stoss side.
