littoral zone

nearshore

The area between the low water mark and the point where the waves cease to have any influence on the land around them.

Offshore

The area beyond the point where waves cease to impact the seabed and in which activity is limited to the deposition of sediments.

foreshore

This is the area lying between the high water mark and the low water mark and is often seen as the most important area for marine activity.

backshore

This is the area between the high water mark and the landward limit of marine activity.

backwash

material moving down the beach

Fetch

geomorphology

earth changes

igneous rock

basalt or granire (volcano)

sedimentary rock

geomorphic processes
