How are submergent features formed?

They are landforms produced from eustatic change in sea level, examples include rias and fjords

1 of 5

How are emergent features formed?

When isostatic movement is faster than eustatic, causing landforms such as raised beaches.

Explain the creation of rias

rias are formed from a eustatic change in sea level. They are drowned river valleys where the floodplain will dissapear beneath rising waters. They have a river valley like cross profile, where the upper course is left dry.

Explain the creation of fjords

Fjords, however, are drowned glacial valleys. They have steep slided sloped with a U shaped cross profile. They have a shallower section towards the end of the river unlike rias, called the threshold. Rejuvination caused the deep glacial valleys
