Depositional and Erosional Coasts

What is a characteristic feature of erosional shores?

• They have a gradually subsiding shore.

• They are commonly found with barrier islands and sand deposits.

• They have well-developed cliffs.

• They are predominantly flat and featureless.

Where do erosional shores typically exist?

• In regions with a lot of sediment deposition.

• Where tectonic uplift of coast occurs.

• Along coastlines with no tectonic activity.

• Inland, away from the coast.

What is an example of an erosional shore?

• The U.S. Atlantic coast

• The Gulf of Mexico coast

• The U.S. Pacific coast

• The Mediterranean coast

What are common features of depositional shores?

• Steep, rocky cliffs

• Tectonic uplift areas

• Barrier islands and sand deposits

• Volcanic activity

What are headlands and what role do they play in relation to wave energy?

• Elevated areas of land that project into a body of water and reflect wave energy

• Protruding bits of land that absorb much wave energy

• Depressions in the coastline that concentrate wave energy

• Flat areas of land that dissipate wave energy

Which of the following are features carved out by wave activity?

• Plateaus and valleys

• River deltas and floodplains

• Wave-cut cliffs and sea caves

• Mountains and hills

What is the term used to describe the bench-like feature formed by wave erosion?

• Sea arch

• Wave-cut bench

• Sea stack

• Cove

What forms when sea caves in headlands erode all the way through?

• Sea stacks

• Sea arches

• Headlands

• Beaches

How do sea stacks form?

• By the accumulation of sand on the shore

• When headlands erode into sea caves

• When the tops of sea arches erode away completely

• Through the deposition of marine life

• A sandbar

• A coral reef
