Erosion and Deposition
Test Review
Question 1
• What is the process where sediment is dropped off in a new location?
• deposition
Question 2
• What force causes mass movement?
• gravity
Question 3
• Where does water above ground deposit sediment?
• Where the water slows down
Question 4
• What is the name of the cave formation that hangs from the ceiling?
• stalactite
Question 5
• What is the name for the particles that are picked up and moved by wind and water?
• sediment
Question 6
• What are the natural forces that move weathered rock particles and soil from one place to another?
• Erosion
Question 7
• How to glaciers cause erosion?
• They move over land and pick up rocks and boulders
Question 8
• What is a stream that flows into a larger stream?
• Tributary
Question 9
• What is the name for all of the land area that drains into a river?
• Drainage basin or watershed
Question 10
• Where does wind deposit sediment?
• Where it slows down – sand dunes
Question 11
• How do caves form?
• Chemical weathering by carbonic acid then sediments erode into groundwater and form stalactites and stalagmites as the sediments are deposited
Question 12
• What is groundwater?
• The term geologists give for water that is underground
Question 13
• What is creep?
• A type of mass movement where sediment slowly moves downhill because of gravity
Question 14
• How does wind move sediment?
• By deflation
Question 15
• Where does mass movement deposit sediment?
• Nearby – not far away
Question 16
• What is the term for how a glacier picks up sediment?
• Plucking
Question 17
• How does water above ground cause erosion?
• Moving water picks up and moves sediments
Question 18
• What is run-off?
• All the water that flows off the land
Question 19
• What are stalagmites?
• A cave formation that grows from the cave floor
Question 20
• What is a glacier?
• A large mass of ice that moves slowly
Question 21
• What is the difference between a continental glacier and a valley glacier?
• A continental glacier is larger and covers large parts of continents or islands; valley glaciers are long and narrow and cover small areas
Question 22
• How do glaciers form?
• When more snow falls in a year than melts, a glacier is formed
Question 23
• Where does water below ground deposit sediment?
• In cave formations
Question 24
• Where do glaciers deposit sediment?
• Where they begin to melt
Question 25
• What is sediment?
• The particles of rock and soil that are moved by erosion
