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
