What is the coastal environment?

• A static environment where only marine areas exist

• A dynamic environment where marine and terrestrial areas influence each other

• An environment where only terrestrial areas exist

• A static environment where marine and terrestrial areas do not influence each other

What are the two main processes that change land and water cover on coasts?

• Erosion and precipitation

• Deposition and evaporation

• Erosion and deposition

• Sedimentation and evaporation

What is the primary reason for the deposition of sediment on the coast?

• When water speeds up and gains energy.

• When water slows and doesn't have enough energy to carry sediment.

• When water evaporates quickly.

• When water temperature increases.

What is coastal erosion?

• The wearing away of land surfaces and loss of beach, shoreline, or dune material

• The accumulation of sand and sediment on beaches

• The formation of new landforms through volcanic activity

• The process of land being uplifted by tectonic forces

Which of the following is NOT an erosional process?

• Hydraulic action

• Abrasion

• Attrition

• Deposition

What is the process called when waves compress air in cracks in a cliff, causing the rock to break apart?

• Hydraulic action

• Abrasion

• Attrition

• Solution

What is the term for the process where rocks and pebbles collide and break into smaller pieces?

• Hydraulic action

• Abrasion

• Attrition

• Solution

Which erosional process involves the chemical dissolution of soluble minerals in rocks?

• Hydraulic action

• Abrasion

• Attrition

• Solution

What is hydraulic action?

• The process of water dissolving minerals in rocks.

• The sheer power of waves smashing against the cliff, trapping air in cracks and causing the rock to break apart.

• The movement of sediment along the coast by wave action.

• The formation of caves by the action of acidic water.

What is abrasion?

• The process of rocks dissolving in water.

• The process of rocks or sand grinding along other rocks or rock platforms.

• The process of rocks being formed from magma.

• The process of rocks breaking due to freezing and thawing.
