deposition
erosion
grooving
weathering
Notice the ice splitting the rock. Which process does the ice contribute to?
deposition
erosion
polishing
weathering
There is a relationship between landforms and wind. Given this relationship, which landform is the result of deposition?
a canyon
a desert
a forest
a mountain
Earth consists of the crust, the mantle, the outer core, and the inner core. Which label do scientists use when they refer to the four parts of Earth shown in the image?
faults
layers
plates
rings
Different types of plate motion produce boundaries that shape different landforms and cause different natural events. Which event will most likely occur where two plates move in different directions and slide against each other?
an earthquake
a fault
a flood
a volcano
Wind, water, and ice are involved in both weathering and erosion. However, weathering and erosion are two different processes. Which sentence states a different between weathering and erosion?
Erosion moves rocks without breaking them down.
Weathering and erosion move rocks to new locations.
Erosion breaks down rocks but doesn't move them.
Weathering moves rocks without breaking them down.
Many rocks contain gaps or cracks. In the diagram, notice the relationship between the rock and the plant. Which statement describes what will happen to the rock and the plant over time?
The rock will crush the plant.
The plant will be buried in the rock.
The plant will grow, and the crack will get bigger.
The rock will stop the plant from growing bigger.
The movement of wind, water, and ice may have the effect of leaving a solid material behind. Which of the following descriptions is an example of such a deposition?
sand in a river delta
space in a sinkhole
sunshine after a storm
a breeze after a hurricane
The flow of water can cause soil erosion. This diagram shows soil erosion caused by rain. If the homeowner wants to stop the process of erosion, what can he or she do?
plant grass
install a sprinkler
fill the hole with dirt
install a chain link fence
During an experiment, Shawn found a cube of sugar dissolves more quickly in a cup of hot water than in a cup of cool water. What might Shawn infer about water temperature and erosion rates?
Water temperature has no effect on erosion.
Colder water will cause rocks to erode more quickly.
Warmer water will cause rock to erode more quickly.
Warmer water will flow down a sloper more forcefully.
Daniel observes that erosion occurs along the banks of two streams where he lives. He takes pictures of the same bends in the two streams every week during the spring season. He notices that there are more changes along the bank of the mountain stream than there are along the bends of the stream that runs through a meadow. What is the likely explanation for this?
The water in the mountain stream is colder.
The water in the meadow stream is moving downhill faster.
The water in the mountain stream is moving downhill faster.
The water in the meadow stream is carrying more sediment.
Earth's crust is made up of plates that rest on the mantle. Which of the following best estimates the distance across one of the plates that make up Earth's crust?
25 miles wide
250 miles wide
2,500 miles wide
25,000 miles wide
This image shows the readings of a seismograph. Which point on the seismograph reading shows an earthquake?
Point A
Point B
Point C
Point D
As two continental plates move together, their edges fold and bend, pushing up mountain ranges. Which statement about a young mountain range would be true?
It will be more snow-covered than the older mountain ranges.
Its mountains will be taller than those of older mountain ranges.
It will be less weathered than older mountain ranges.
Its mountains will be less volcanic than those of older mountain ranges.
Earth's surface is constantly changing. Which process begins in Earth's mantle below Earth's crust?
an earthquake
the forming of a mountain range
the sinking of a fault line
a volcanic eruption
Glossopteris is a fossil of which of the following?
a living plant
an extinct plant
a living animal
an extinct animal
Sometimes, magma forces plates to push apart. Which statement best explains how magma reaches Earth's surface?
Gravity pulls the magma to the surface.
Plate movement forces the magma upward.
Heat and pressure cause the magma to rise.
Magnetism attracts the magma to the surface.
What is the theory proposed by Alfred Wegener called?
continental drift
continental shelf
continental stability
continental fossils
How can fossils be used to prove the theory of continental drift?
An earthquake can occur where ever a fault exists in Earth's crust. Suppose an earthquake occurred under an ocean. Explain why such an event would generally be considered less destructive than an earthquake on land.
