What do we call the form of weathering that involves temperatures fluctuating around 0°C and is the dominant mechanical weathering process on coastlines?

Freeeze-thaw weathering

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.
