Which consequence results when thermal expansion weakening occurs in sea cliffs?

💡 Explanation

Increased abrasion and wave-cut platform growth occurs due to a positive feedback; thermal weakening facilitates weathering. This mechanical weathering degrades cliff structure, increasing sediment yield available for coastal abrasion, because wave energy is thus focused on weakened zones, rather than dune accretion.

• Which outcome occurs when wave energy dissipates unevenly along a coastline featuring alternating headlands and bays?
• Which outcome slows stalactite growth where CO2 fluctuates?
• Which outcome results due to seasonal freeze-thaw in tundra?
• Which outcome results when wave-driven dissolution erodes coastal chalk cliffs?
• Which process initiates headwall erosion to form distinct glacial cirques given seasonal freeze-thaw cycles?
• Which risk increases as permafrost thaws due to increased global temperatures under buildings with pile foundations?
