11. What is the difference between constructive and destructive forces?
Constructive forces build up landforms, while destructive forces break down landforms

12. What does a seismograph measure?
The intensity of an earthquake

13. What happens when rocks rub against each other in running water?
They become smooth

14. What happens when a volcano erupts?
Magma is forced out an opening in the Earth’s crust. It then becomes lava and hardens.

15. The center of the Earth is extremely hot. Why, then, is it solid?
Because of pressure

16. What can happen when water freezes inside the crack of a rock?
It can break the rock

17. How can a dam prevent flooding?
By holding back and regulating the flow of water

18. What forces of nature can erode a rock?
Wind, rain, ice

19. How does pollution speed up the erosion of rocks?
By causing acid rain, which dissolves rock faster

20. What causes states to have a lot of earthquakes?
They are located on a fault line

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

22. Give an example of a constructive force.
A volcano, fault lines cause a mountain to form, deposition forming a delta, etc.

23. Give an example of a destructive force.
A volcano top blowing, landslides, mudslides, avalanches, erosion by wind, rain, or ice, etc.

24. 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.

25. The following pictures show the effects of wave action on a rock
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?

26. What type of weathering is occurring in this picture?
water weathering – water is causing erosion by moving the sand
wind weathering – wind is causing erosion by moving the sand

27. What type of weathering is occurring in this picture?
Water is wearing away the rock by flowing over it.
