bed load
describes sediments that are too heavy or large to be kept in suspension or solution and are pushed or rolled along the bottom of a streambed
triangular deposit, usually made up of silt and clay particles, that forms where a stream enters a large body of water
broad, flat, fertile area extending out from a stream's bank that is covered with water during floods
curve or bend in a stream formed when a stream's slope decreases, water builds up in the stream channel, and moving water erodes away the sides of the streambed
water that flows downslope on Earth's surface and may enter a stream, river, or lake; its rate is influenced by the angle of the slope, vegetation, rate of precipitation, and soil composition
in a stream, is created when materials, such as silica (SiO2), calcium (Ca), and sodium (Na), dissolve in the stream's water
stream bank
ground bordering each side of a stream that keeps the moving water confined
state in which small particles, such as silt or sand, are held up and carried along by the turbulence of a stream's moving water
land area drained by a stream system
Surface Water Movement
-earth’s water supply is recycled in the water cycle
-water molecules evaporate from a body of water, condense into cloud droplets, fall as precipitation back to earth’s surface and then soak into the ground
Stream channel
narrow pathway carved into sediment or rock by the movement of surface water
Young Stream
water moves fast, large pieces of sediment flows with the channel
mature stream
water picks up speed as it move but not as fast at young stream. Stream picks up large pieces but leaves sand behind
old stream
water moves slow and collects larger sediments
process by which lakes become rich in nutrients from the surrounding watershed, resulting in a change in the kinds of organisms in the lake
