Erosion 1
water that flows over the ground surface rather than soaking into the ground.
Runoff
A channel through which water is continually flowing downhill
Stream
Mrs. Adragna notices that sand is deposited at the end of the river, what landform is being created?
Delta
When visiting a waterfall, where is the greatest amount of erosion occurring? Why?
At the bottom of the falls, because of the powerful plunging force of water crashing down.
A landform made of sediment that is deposited where a river flows into an ocean or lake.
Delta
A wide, sloping deposit of sediment formed where a stream leaves a mountain range.
Alluvial fan
What happens to sediment as it flows downstream? What process takes place as the River slows down?
Sediment is transported downstream.
Though the process of deposition.
any large mass of ice that moves slowly over land.
Glacier
Continental Glacier
Time in Earth's history during which glaciers covered large parts of the surface.
Ice Age
Observe as the glacier with pebbles move till at the bottom of the glacier. What does the glacial till form at the bottom of the glacier?
Moraine
The process by which a glacier picks up rocks as it flows over the land.
Plucking
The sediments deposited directly by a glacier.
Till
The movement of water and sediment down a beach caused by waves coming in to shore at a angle.
Longshore Drift
Is a loop-like bend in the course of a river.
Meander
