6

Which describes sand?

A
fine-grained
B
retains water

8

Which feature is created by deposition from rivers?

A
rills
B

9

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.
10

Which condition leads to a slower rate of weathering?

A
porous rocks
B
cold climates
C
hard minerals
D
high temperatures
11

Which substance would most likely form sedimentary rock?

A
cooled lava
B
melted rock
C
changed igneous rock
D
small pebbles
12

A mineral forms in water heated by magma inside Earth.Which statement best describes this mineral?

A
The mineral formed through evaporation.
B
The mineral crystallized from molten material.
C
The mineral formed when a hot water solution cooled.
D
The mineral likely has all the same properties as the surrounding rock.
13

Some consumers, like lions, do not eat plants or any other producers. They only eat other animals.How do lions obtain the carbon they need?

A
by eating animals that have carbon-based molecules stored in their bodies
B
by breathing it in from the atmosphere in the form of carbon dioxide
C
by absorbing carbon-based molecules through their skin from the soil
D
by drinking water that contains carbon dioxide
15

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.

size, weight, luster
D
streak, luster, magnetism
18

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.

Rocks are broken into smaller particles.
19

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
