In a stream, deposition occurs on the inside bend, and erosion occurs on the outside bend.
Size, shape, density, and saturation affect deposition.
The agents of erosion are gravity, running water/streams, wind, glaciers, and waves.
Contact Metamorphism is when a body of magma pushes up and intrudes on other native
rocks; the surrounding rocks get baked because of the heat (not melted). Regional
Metamorphism is when large sections of the lithosphere collide; rocks are squished and
subjected to high temperature and pressure. These rocks are usually extremely folded.
5. Chemical weathering is the breakdown of rock through a change in mineral or chemical
composition. Physical weathering is the breakdown of rock into smaller pieces without
chemical change.
6. Erosion is the weathering of rock producing particles that are transported sediments.
Weathering is the chemical and physical breakdown of rocks at or near Earth’s surface.
