Weathering, Deposition, and Erosion

process of wearing away earth materials by water, wind, or ice (it makes a physical change)

weathering in which rocks are physically broken into pieces (this is also called physical weathering)

a hole or tunnel in the ground that an animal (such as a rabbit or fox) makes to live in or for safety

happens when compounds from burning coal, oil, and gas react chemically with water and forms acid

the process by which rocks, sand, and sediment are deposited by the forces of erosion

weathering in which rocks and minerals are dissolved

materials deposited by some natural process

a piece of land shaped like a triangle that is formed when a river splits into smaller rivers before it flows into an ocean

a very large area of ice that moves slowly down a slope or valley or over a wide area of land

a deep valley with steep rock sides and often a stream or river flowing through it

a long wall of soil built along a river to prevent flooding

when water comes in contact with granite. Feldspar crystals inside the granite react chemically forming clay minerals

give an example of mechanical weathering

slow breaking down of rocks into smaller pieces
