River Systems
Triangle-shaped deposit of sediment, pebbles, and rocks found where one river flows into another body of water.
What is a River Delta?
Steam falls under this water cycle category:
What is evaporation?
Network of river channels separated by "braid" bars that divide and constantly shift.
What is a braided-stream?
Extremely fertile, loose sedimentary material that can be deposited in stream channels.
What is alluvium (of the earth).
Geographic area drained by one river system.
What is a watershed?
Stream velocity does this upon entering into a new body of water?
What is decrease?
Occurs when frozen snow converts directly to steam (no melting).
What is sublimation?
Flat land surrounding rivers that periodically floods during spring flooding.
What is a flood plain?
When a river or stream flows into another river.
What is a tributary?
Geographic line that divides North America into water sheds that drain into different oceans.
What is the continental divide?
Fan-shaped deposits of gravel, sand, and alluvium formed when streams flow onto a plateau or plain.
What is an alluvial fan?
4 main processes of the water cycle?
What are evaporation, condensation, precipitation, and transpiration?
Flowing water, such as a brook, river, or even an ocean current.
What is a stream?
The greater the slope the greater the stream:
What is velocity?
A measure of the ability of a porous material to allow fluids to pass through.
What is permeability?
When two rivers meet and merge together:
What is a confluence?
The construction of more parking lots, streets, and driveways will increase the amount of this?
What is run-off?
The tidal mouth of a large river, where the tide meets the stream.
What is an estuary?
Water flows the fastest on this side of the river bend:
What is the outside bend?
This is how much water is flowing out of a river in a given amount of time:
What is discharge?
A curve that develops naturally in the path of a river over generally flat land.
What is a meander?
The chemical formula for water:
What is H20?
wall built along a shore or bank to prevent floods by giving a raised, uniform freeboard and by allowing unimpeded flow to water in a channel.
What is a flood wall?
This cycle has no set beginning or end, study can be initiated at any point along the way:
What is the water cycle?
The water is a river moves fastest here:
What is the top, middle portion of stream flow?
