Correct answer is mechanical weathering.
Mechanical weathering - occurs when physical forces break rock into smaller and smaller pieces without changing the rock's mineral composition.
Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
