Coastal Weathering Quiz

What is freeze-thaw weathering?

• The process where rocks break down due to chemical reactions.

• The breakdown of rocks by living organisms.

• The process where water freezes in cracks of rocks, expands, and causes the rock to break apart.

• The erosion of rocks by the force of moving water.

Which type of weathering involves the reaction of rock minerals with chemicals like acids?

• Biological weathering

• Chemical weathering

• Freeze-thaw weathering

• Abrasion

What role do plants and animals play in coastal weathering?

• They physically break rocks apart.

• They have no significant role.

• They contribute to chemical weathering.

• They contribute to biological weathering by breaking down rock through physical or chemical means.

What is hydraulic action in the context of coastal erosion?

• The smoothing of rock surfaces by sand and pebbles.

• The chemical reaction between water and rock minerals.

• The force of waves breaking against rock and forcing air and water into cracks.

• The transport of eroded material along the coast.

What does abrasion refer to in the process of coastal erosion?

• The breakdown of rocks through chemical reactions.

• The wearing away of cliff faces by rock particles driven by waves.

• The action of rocks breaking into smaller pieces through collisions.

• The dissolving of rock by acidic water.

What is corrosion in terms of coastal processes?

• The mechanical scraping of rock surfaces by other rocks.

• The chemical dissolution of rocks by seawater.

• The breaking of rocks by plant roots.

• The freezing of water in rock cracks.

What does attrition refer to in the context of coastal erosion?

• The erosion of rocks by chemical reactions.

• The rounding and smoothing of rock particles as they collide with each other.

• The biological breakdown of rocks by organisms.

• The force of water entering rock cracks.

Which process describes the movement of eroded materials along the coast?

• Hydraulic action

• Abrasion

• Attrition

• Transportation

What is the main cause of freeze-thaw weathering?

• High temperatures during the day.

• The presence of organisms.

• Water freezing and thawing in rock cracks.

• Acidic conditions in the environment.

Which type of weathering is primarily caused by the oxidation of minerals?

• Biological weathering

• Chemical weathering

• Physical weathering

• Freeze-thaw weathering
