Landform

• process by which exposed rock is broken down by rain, frost, wind, or other elements of weather

• process by which weathered and eroded material is deposited by wind, water, and ice

• the movement of weathered material by wind, water, or ice (e.g. glaciers)

• a physical structure on Earth that occurs naturally
