Water that does not soak into the ground or evaporate is called _______
Runoff
All of the water the feeds a lake or river system is called a(n) ___________
Watershed
A(n) ___________ is a curve in a river that has been cut off from the rest of the river.
Oxbow Lake
A(n) _______________ is a deposit from wave action bringing material away from the shore.
Sandbar
A curve in a river system is called a(n)
Meander
A(n) ___________ is a triangular shaped deposit of material as a river enters a larger body of water.
Delta
As waves crash on the shore, a(n) __________ is created that pulls material away from the beach.
Undertow
_____________ is when waves get deflected by the shoreline causing them to move down the shore.
LongShore Current
A(n) _____________is a triangular shaped deposit of material at the base of a mountain or hill.
alluvial fan

Does water moving faster move more material? t/f
True
which feature formed as a result of the growth of a spit?
A baymouth Bar
Describe how barrier islands and tombolo form.
Undertow pulling away
What bodies of water are protected from the oceans waves?
lagoons
Where did the sediment needed to build depositional features shown come from?
Erosion
What are 3 things that can happen to water when it rains?
Evaporation, runoff, soak into the ground.
Why do meanders form on rivers?
the river wants to continue the way it goes in a curving pattern they connect and eventually become a meander.
How do deltas form?
A river enters a larger body of water and loses energy dropping material/sediments.
Why do beaches have differences in the sand?
The rocks, the climate, if people go there often.
