Large difference between day and night temperature increases which type of weathering?

Answer and explanation

Correct answer: Physical weathering

Direct answer: Option C, physical weathering. In areas with a large day-night temperature range, rocks heat during the day and cool at night. Heating causes expansion and cooling causes contraction. Repeated expansion and contraction produce stress, cracks, and eventually smaller pieces without changing the rock’s chemical composition. That is physical or mechanical weathering. Option A is less suitable because chemical weathering changes minerals through reactions with water, oxygen, or acids. Option B involves plants, animals, or organisms. Option D is deposition, the settling of material, not its breakdown. Cue: repeated heat and cold means physical breaking.
