Physical weathering is usually caused by Atmospheric changes, such as high or freezing temperatures. When water freezes and expands in the crevices, frost wedges are created, causing the rock to crack. In addition, extreme temperature changes, such as rapid heating and cooling, can cause the rock to expand and contract.

What are the 4 causes of weathering?

water, ice, acid, salt, plants, animals and temperature changes All are weathering agents. Once the rock is broken down, a process called erosion removes fragments of the rock and minerals. No rock on Earth can resist the forces of weathering and erosion.

What are the 5 causes of weathering?

What are the 5 causes of weathering?

• Physical weathering. Physical or mechanical weathering is the breaking down of rock into smaller fragments.
• chemical weathering.
• water erosion.
• wind erosion.
• gravity.

Is weathering caused by weather?

Wind, rain, and waves all cause weathering. Wind can blow fine grains of sand onto rocks. These wear away the rock and weather it. Rain and waves hitting the rock also wear it out over a long period of time.

What types of weathering form?

There are three types of weathering, Physics, Chemistry and Biology.
