What are the 4 types of weathering?
There are four main types of weathering. These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard. However, a very small amount of water can cause them to break.

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 3 types of weathering?
Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.
