Question

the 4 ways that the sea erodes

Answer 1

The sea moves water across surfaces, and so removes minuscule amounts of rock, but major amounts of loose aggregate, beach sand or even rocks.

Sea water can also attack with acidity or other chemical reactions.

Aggregates like sand are also moved over, slammed into rock, causing fairly rapid erosion.

Oceans hurl masses of ice against the land.

Ice water actually gets into cracks in the rock, where it freezes if temperatures are low enough.

The freezing pries off fragments of the rock.

Water causes rapid cooling of rock heated in the sun,and so fractures it, causes fissures.
