The type of weathering in which rock is physically broken into smaller pieces
The process that breaks down rock through chemical changes
the grinding away of rock by other rock particles carried in water, ice, wind, or gravity
Process that splits rock when water seeps into cracks, then freezes and expands.
characteristic of materials such as sand and gravel that allow water to pass easily through them
The process by which sediment settles out of the water or wind that is carrying it, and is deposited in a new area
