Marine Processes

What is the process called where rocks and sediments are worn away by the action of water, ice, or wind?

• Deposition

• Erosion

• Compaction

• Cementation

Which type of marine transportation involves sediment rolling along the seabed?

• Suspension

• Saltation

• Solution

• Traction

What is the term for the movement of materials through water in a series of leaps or bounces?

• Suspension

• Saltation

• Solution

• Traction

Which of the following is NOT a type of coastal erosion?

• Hydraulic action

• Abrasion

• Attrition

• Deposition

What happens during the process of solution in marine transportation?

• Sediments dissolve in water and are carried along in solution.

• Large rocks are broken down into smaller pieces.

• Sediments are carried in the flow of the water.

• Sediments bounce along the bottom of the water body.

What is the effect of longshore drift along coastlines?

• It decreases beach material.

• It transports sediment parallel to the shore.

• It creates waves.

• It solidifies sand on beaches.

Which process describes the breaking down of rocks through chemical changes, often influenced by seawater?

• Physical weathering

• Biological weathering

• Chemical weathering

• Mechanical weathering

What role does abrasion play in the erosion of coastlines?

• Rocks and sediments are dissolved by acids in the water.

• Water compresses air in cracks, breaking the rock apart.

• Sediments in the waves grind down cliff surfaces like sandpaper.

• Rocks are carried away by animals or plants.
