What causes volcanoes?

magma moves to the top of Earth's crust at fault lines

Why are rocks at the bottom of a river smoother than rocks on a hillside?

Running water has weathered the rocks.

What is the main difference between a dam and a levee?

dams cross a river; levees are along sides

Sea grass can grow on a sand dune. How is the sea grass MOST likely to affect the sand dune?

The dune will erode more slowly and may even grow.

Which is true of a canyon?

The are made by rivers cutting through land.

Which of the following is NOT a cause of weathering?

a river carries sand and sediment downstream

Why is terracing of farmland beneficial?

It slows down water erosion of topsoil.

How do dams help to control flooding?

Dams can be opened when needed and they can form lakes.

Which of these is an example of storm drain management?

removing debris and trash from drains

What kind of information is NOT recorded on a seismograph?

information about when the next earthquake will occur

What happens to a hillside when it rains?

Water carries sediment down its sides.

How do humans cause weathering?

walking across grass so much that a dirt path forms

How does a seismograph help humans?

We can use them to predict tsunamis.

How can a levee help prevent flooding?

It keeps rising water inside stream channels.

Why are barrier islands good for the coast of Georgia?

protect mainland from weathering and erosion

Answers

1
What type of human intervention is pictured to control flooding?
levee
beach reclamation
dam
jetty
2
What causes volcanoes?
magma moves to the top of Earth's crust at fault lines
chemical weathering produces holes in Earth's crust
strong hurricanes break up Earth's crust
living organisms shake the Earth's crust
3
Which process is NOT destructive?
weathering
erosion
deposition
plate tectonics pulling apart
4
Why are rocks at the bottom of a river smoother than rocks on a hillside?
Tectonic plates have carved out the rocks.
The force of gravity has sanded down the rocks.
Wind erosion has worn away at the rocks.
Running water has weathered the rocks.
5
Which of the following does NOT cause erosion?
temperature
rivers
rain
wind
6
What is the main difference between a dam and a levee?
dams are temporary; levees are permanent
dams are along sides of river; levees cross a river
dams cross a river; levees are along sides
levees provide electricity; dams cause weathering
7
Sea grass can grow on a sand dune. How is the sea grass MOST likely to affect the sand dune?
The dune will move toward the land.
The dune will erode more slowly and may even grow.
The dune will move toward the ocean.
The dune will erode more quickly.
8
A delta forms by which process?
condensation
deposition
faulting
flooding
9
Which is true of a canyon?
They are built up by ocean waves.
They are built by water depositing sediment.
The are made by rivers cutting through land.
They are built up by wind deposition.
10
Which of the following is NOT a cause of weathering?
waves constantly crash into a cliff
a plant grows in a crack in a rock
a river carries sand and sediment downstream
sand blows against a rocky surface
11
Where in Georgia could beach nourishment take place?
downtown Atlanta
piedmont
Buford Dam
barrier islands
12
Which is an example of a landform made from destructive forces?
mountain
delta
canyon
glacier
13
Why is terracing of farmland beneficial?
It slows down water erosion of topsoil.
It allows scientists to record different types of soil on different farms.
It allows farmers to plant many different types of crops.
It slows down wind erosion of topsoil.
14
Which process is NOT constructive?
erosion
wind deposition
plate tectonics colliding
water deposition
15
This beach has been eroded. What can be done to build up the beach again?
beach weathering
beach friction
beach nourishment
contour plowing
16
A city builds levees on the banks of a river. What is the city MOST likely trying to reduce?
earthquakes
landslides
flooding
hurricanes
17
Which of the following is NOT a means of flood control?
levee
seismograph
dams
storm drain
18
How do dams help to control flooding?
Dams pull water downstream before it can flood
Dams keep rising water inside stream channels.
Dams act as a drain and collect water runoff.
Dams can be opened when needed and they can form lakes.
19
What is the purpose of contour plowing?
to prevent water erosion
to increase safety during harvest
to prevent deposition
to prevent wind erosion
20
Which model best shows erosion?
shaking a sugar cube in a jar
putting a rock in the freezer
putting salt in a big pile
blowing sugar with a straw
21
Which process forms underground caves in limestone?
terracing
physical weathering
tectonic plates
chemical weathering
22
Which of these is an example of storm drain management?
training ocean animals to clear drains
increasing the use of recycled materials
removing debris and trash from drains
clearing pollution from the air
23
What kind of information is NOT recorded on a seismograph?
location of the focus point or the epicenter
strength of an earthquake
information about when the next earthquake will occur
when an earthquake already occurred
24
What happens to a hillside when it rains?
Water carries sediment down its sides.
Rain water deposits sediment on the top.
Wind carries sediment away from it.
Wind deposits sediment on top of it.
25
How do humans cause weathering?
walking across grass so much that a dirt path forms
water freezing in a crack in a rock
acid rain wearing away at limestone
a chipmunk digs a hole near the base of a rock
26
How does a seismograph help humans?
We can use them to predict earthquakes.
We can use them to control flooding of rivers.
We can use them to weaken volcanic eruptions.
We can use them to predict tsunamis.
27
How can a levee help prevent flooding?
It keeps rising water inside stream channels.
It pulls water downstream before it can flood.
It acts as a drain when water gets too high
