An example of mechanical weathering is salt crystallization weathering. This process occurs when saltwater seeps into cracks in rocks, and as the water evaporates, the salt crystallizes and expands, exerting pressure on the rock and causing it to break apart mechanically.
Which is an example of mechanical weathering?
water combining with rock crystals to form hydrates
colonies of bacteria releasing chemical enzymes and acids that break down minerals
carbonic acid in water dissolving limestone
salt crystallization weathering
