2- 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.

3- While Physical weathering breaks down a rock’s physical structure, chemical weathering alters a rock’s chemical composition. Then, Physical weathering works with mechanical forces, such as friction and impact, while chemical weathering takes place at the molecular level with the exchange of ions and cations.

4- Physical Weathering is In Nature. When water in a river or stream moves quickly, it can lift up the rocks from the bottom of that body of water. As in ice forms in the cracks of a street, the water expands and pushes against the surrounding rock, making the cracks wider, eventually breaking apart the rock.
