River correct answers Carry water back to ocean, gravity drives flow, transport sediment, drain
to specific landscape (drainage basin)
Drainage Basin correct answers All of the upstream area that drains into a given river or stream
Tributaries correct answers All the smaller rivers and streams that merge with the larger river
that makes it all the way to the ocean
Gradient correct answers The slope of the land
Discharge correct answers The volume of water carried in m3/sec
Velocity correct answers The speed the river moves in m/sec
Headwaters correct answers Where the river starts
Base correct answers Where the river ends up, usually sea level
Sediment Transport correct answers Very fine sediment is suspended in water sediment and
move all of the time, larger sediment rolls and hops (saltation) along the bed., very large

Braided River correct answers Occurs where the sediment size is coarse (gravel and larger), lots
of sediment is supplied to channels, common in landscapes with rapid erosion, mountainous
landscapes with glaciers.
Cascade River correct answers Occurs where gradient is steep,
close to source, and
ground is hard (large rocks).
Meandering River correct answers Occurs where sediment is fine (sand and clay),
gradient is low, and
a floodplain has developed, most common close to base.
Point Bar correct answers Inside of meandering river bend, slower velocity, deposition
Cut Bank correct answers Outside of meandering river bend, faster velocity, erosion
