__________ represent the features of both emergence and submergence.

  • A.Compound coasts
  • B.Neutral coasts
  • C.Simple coasts
  • D.Retrograded coasts

Answer: A

The answer is Compound coasts.

A compound coast shows landforms of both emergence (such as raised beaches and marine terraces, left as the land rose or sea level fell) and submergence (such as rias or drowned valleys, formed as the sea rose), because the coast has gone through both kinds of change.

Neutral coasts, such as deltas, alluvial plains and volcanic coasts, owe their form to neither emergence nor submergence. 'Simple' and 'retrograded' coasts do not describe a coast with both sets of features.
