I need to know what physical weathering and chemical weathering is for a science project!
Oksana_A [137]
Ok ok no fret im here to help as best as i can :)
Weathering is a process that breaks down or changes rocks into smaller pieces. Various atmospheric aspects are responsible for weathering processes. Weathering is different from erosion. Erosion is the movement of rock pieces and sediment from one area to another. Weathering is the breaking down of rocks and erosion is a wearing away of rocks. There are two main types of weathering: physical (or mechanical) weathering and chemical weathering. Quite often, both forms of weathering will occur together

Physical weathering is also known as mechanical weathering. This type of weathering occurs when rocks and other landforms are broken down by physical factors in the environment. These physical factors include wind, water, sun, ice and temperature changes
