- Weathering is a process of breakdown of rocks at the Earth's surface, by the action of water, ice, acids, salts, plants, animals, gravity, and changing temperature.
- Weathering has three types what are those?

- What is PHYSICAL WEATHERING?
- Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water.
- Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.
- Exfoliation occurs as cracks develop parallel to the land surface a consequence of a reduction in pressure during uplift and erosion.
- What are the two main types of physical weathering?
- Freeze-thaw and Exfoliation
- Where does it occur?
- Physical weathering happen specially in places where there is little soil and few plants grow, such as in mountain regions and hot deserts.
- Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.
