Using at least three sentences describe the process of weathering, and explain how it can happen physically or chemically. square

Weathering is the process by which rocks and minerals are broken down into smaller pieces by physical, chemical, or biological means. Physical weathering occurs when rocks are physically broken down into smaller pieces without changing their chemical composition. This can happen through processes such as freeze-thaw weathering, where water seeps into cracks in the rock and then freezes, causing the rock to expand and break apart. Chemical weathering, on the other hand, involves the alteration of the chemical composition of the rock. This can happen through processes such as oxidation, where minerals in the rock react with oxygen in the air to form new compounds, or dissolution, where minerals in the rock dissolve in water. Biological weathering can also occur, where plants and animals contribute to the breakdown of rocks.
