Process of breaking down rock
What is Erosion?
100
As the water volume increases the river erodes the banks and carries sediment through it.
Why does an increase of water volume cause more sediment to be carried through it?
100
When sediments are moved to a new location.
What is deposition?
200
Rocks are broken down by sand,wind,gravity and water
What is physical weathering?
200
Slow water flow on a sloped soil surface will most likely cause a stream of water to flow over the surface.
Why would slow water flow on a sloped soil surface cause a stream of water to flow over the surface?

Chemical and Physical Weathering
What are the two processes that change landform shapes.
300
Rocks are broken down because of exposure to water acids and gases.
What is chemical weathering?
300
A river erodes and builds up more sediment than can be carried down river.
Why does a river leave behind sediment deposits after a flood?
300
Rainstorms
What natural occurance has the largest impact on mountain formations?
400
Destructive process that breaks down and changes rocks.
What is weathering?
400
Vegetation growing on the hillsides traps and holds sediments.
Why does vegetation growing on a hillside have an impact on masswasting during a rainstorm?
400
River water flows slowly into the ocean and deposits large amounts of sediment.
What causes a Delta to form?
500
Water freezes, expands, and melts in the cracks of rocks.
What is Frost Wedging?
500
What happens when water flows downhill?
More sediment is carried to lower elevations.
500
When the water level rises during a rainstorm.
What causes a river to carry more sediment?
