Week 3

drainage basin A system of rivers and streams that drains an area

delta A fan-shaped (triangular) deposit of earth materials at a mouth of a stream

meander A curve or loop in a channel

landform A natural structure on Earth’s surface

canyon A V-shaped valley eroded by a river or stream

plateau A large, nearly level area that has been lifted above the surrounding area

channel the course or path the water takes in a stream or a river

weathering The breaking down and wearing away of earth materials caused by water, wind, or ice

erosion The movement of weathered materials by water, wind, or ice

deposition The process by which materials eroded by water, wind, or ice are dropped in a new place

sediments Bits of rock, soil, sand, shells, and the remains of organisms

basin a low area in which sediments are often deposited
