Answer:
Freeeze-thaw weathering
Step-by-step explanation:
Freeze- thaw weathering involves the breakdown of rock particles into smaller fragments through continuous fluctuations in the temperature of the water bodies. This form of weathering is common along coastlines. The water enters the rocks and then freezes when there is a decrease in temperature. The freezing expands the rock particles and aids frictions between the rock parts. This helps in the breakdown of the rocks to smaller particles.
It involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines
