Which describes sand?

A
fine-grained
B
retains water
C
water drains quickly
D
good for growing crops
3

Which statement best describes a characteristic of deposition?

A
Sediment settles in a new place due to size, water speed, and land shape.
B
Sediment is removed from a new surface location.
C
Moving water affects where sediment travels.
D
Rocks are broken into smaller particles.
4

Which correctly lists the three processes that are affected by freeze and thaw cycles?

A
creep, landslide, and deposition
B
deposition, creep, and weathering
C
landslide, slump, and deposition
D
slump, weathering, and creep
5

How do erosion and deposition work together to create a moraine?

A
Waves cause erosion along coastlines and deposit sand away from the shore.
B
Surface water in rivers causes erosion, carrying sediment that gets deposited near an ocean.
C
Glaciers cause erosion as they melt, carrying sediment that gets deposited in a thick layer.
D
Winds cause erosion by blowing around sand that gets deposited in large piles.
6

Which process is responsible for changing the composition of rock?

A
erosion
B
abrasion
C
chemical weathering
D
mechanical weathering
8

Which particle has a high rate of deposition?

A
a low-density particle
B
a small particle falling off a cliff
C
a particle with jagged, rough ends
D
a large round particle settling on a surface
9

Which formation is one feature of karst topography?

A
caves
B
kettles
C
meanders
D
oxbow lakes
10

Which condition leads to a slower rate of weathering?

A
porous rocks
B
cold climates
C
hard minerals
D
high temperatures
12

How do erosion and deposition work together to form sand dunes?

A
Waves cause erosion along coastlines and deposit sand away from the shore.
B
Erosion occurs as surface water carries sediment and the sediment is deposited near oceans and lakes.
C
Glaciers cause erosion through the movement of large chunks of ice, which are deposited and form depressions.
D
Erosion occurs through deflation, and sand that was picked up is deposited against an obstruction.
13

Which increases the rate of soil formation?

A
mixed layers
B
more precipitation
C
cooler temperatures
D
very hard parent material
15

How are deltas formed?

A
erosion of softer rock
B
connection of channels
C
deposition from flow into a lake or an ocean
D
creation of large, flat areas by flooding deposits
16

Which describes the horizons in a soil profile?

A
Horizon A is mineral deficient.
B
Horizon O forms from organic material.
C
Horizon B undergoes the least amount of change.
D
Horizon C is most affected by the soil formation process.
17

Which describes a climate effect on the rate of weathering?

A
Cold climates favor mechanical weathering.
B
Chemical reactions occur slower at higher temperatures.
C
Lower precipitation levels lead to more chemical reactions.
D
The chemical reaction rates of minerals are not impacted by temperature.
19

Which is one place that glaciers are found?

A
in the ocean
B
in the tropics
C
at low altitudes
D
at high latitudes
