18
What is the difference between constructive and
destructive forces?

• Constructive forces build up landforms, while
  destructive forces break down landforms

19
What does a seismograph measure?

• The intensity of an earthquake

20
What happens when rocks rub against each other in
running water?

• They become smooth

21
What happens when a volcano erupts?

• Magma is forced out an opening in the Earths
  crust. It then becomes lava and hardens.

22
The center of the Earth is extremely hot. Why,
then, is it solid?

• Because of pressure

23
What can happen when water freezes inside the
crack of a rock?

• It can break the rock

24
How can a dam prevent flooding?

• By holding back and regulating the flow of water

25
Where does the magma from volcanoes come from?

• Deep inside the Earth

26
What forces of nature can erode a rock?

• Wind, rain, ice

27
How does pollution speed up the erosion of rocks?

• By causing acid rain, which dissolves rock faster

28
What causes state or are to have a lot of
earthquakes?

• They are located on a fault line

29
A new island formed in Iceland in 1963. What was
most likely the cause of this island forming?

• A volcano

30
Give an example of a constructive force.

• A volcano, fault lines cause a mountain to form,
  deposition forming a delta, etc.

31
Give an example of a destructive force.

• A volcano top blowing, landslides, mudslides,
  avalanches, erosion by wind, rain, or ice, etc.

32
Why do scientists think there was originally one
supercontinent that split up into the seven
continents we now have?

• The continents seem to fit together like a puzzle
  and fossils for animals from one continent have
  been found on other continents, suggesting they
  were once one.

33
Which of the fossil layers shown is the most
recent?
34
The following pictures show the effects of wave
action on a rock. Which would be the last
picture if you put the pictures in order?
35
What type of weathering is occurring in this
picture?

1. water weathering water is causing erosion by
   moving the sand
2. wind weathering wind is causing erosion by
   moving the sand

36
What type of weathering is occurring in this
picture?

• Water is wearing away the rock by flowing over it.

37
What do glaciers form?

• Valleys (both U-shaped valleys and V-shaped
  valleys, depending on the size of the glacier.

your house to make a model of the Earth.
