Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.
There are two types of weathering: mechanical and chemical.
Mechanical weathering is the disintegration of rock into smaller and smaller fragments..
What are the 4 main 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.

What is physical weathering?Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. When these rocks drop, they collide with other rocks, breaking tiny pieces off.Ice wedging. Ice wedging causes many rocks to break. … Plant roots. Plant roots can grow in cracks.
What are 2 kinds of weathering?
Two important classifications of weathering processes exist – physical and chemical weathering; each sometimes involves a biological component. Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure.
What are the 5 causes of weathering?
What Forces Cause Weathering & Erosion?Physical Weathering. Physical or mechanical weathering is the disintegration of rock into smaller pieces. … Chemical Weathering. Chemical weathering is the disintegration of rock caused by chemical alteration of the mineral structure. … Water Erosion. … Wind Erosion. … Gravity.
