Which is an example of mechanical weathering?
Mechanical weathering involves mechanical processes that break up a rock: for example, ice freezing and expanding in cracks in the rock; tree roots growing in similar cracks; expansion and contraction of rock in areas with high daytime and low nighttime temperatures; cracking of rocks in forest fires, and so forth.

What are 4 examples of weathering?
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

What is mechanical weathering and its example?
During mechanical weathering, no new substances are produced. The rock gets smaller, but it stays the same kind of rock. For example, water sometimes gets into the tiny cracks in boulders. If that water freezes, it expands, opening the crack even more and eventually splitting the rock into pieces.

What are the 7 factors of mechanical weathering?
Expert-Verified Answer. Ice wedging, pressure release, plant root growth, and abrasion can all cause mechanical weathering. in the cracks and pores of rocks, the force of its expansion is strong enough to split the rocks apart.
