1. Speed
Ans: how fast an object is moving
2. Which of the following statements BEST describes the
locations of volcanoes?
Ans: Most volcanoes are located along the edges of some
continents or in chains off the coast of continents.
3. Some plate boundaries have
Ans: active volcanoes but some don't, and almost all volcanoes
are at boundaries.
4. The typical speed of a plate is Ans: a few centimeters
per year.
5. An atmospheric instability causes a column of air to
rotate. Ans: Tornado
6. A moist mass of air over warm ocean water condenses
as it rises, forming a massive spinning storm. Ans:
hurricane
7. This type of storm is common at cold fronts and often
produces lightning.
Ans: Thunderstorms
8. This is the most violent storm on Earth. Ans:
tornadoes.
9. A hurricane has an Ans: eye in the center that is very
calm.
10. Lightning is an Ans: electric glow that can be seen
during a storm.
,11. Differences in temperature within Earth and within the
plates result in
Ans: -processes that move plates.
12. A low-lying cloud of small water droplets that reduces
visibility to less than 1 km (0.62 mi) is called Ans: fog
13. Which radiation can greenhouse gases absorb that
nitrogen and oxygen cannot?
Ans: Greenhouse gases can absorb infrared radiation, which
nitrogen and oxygen cannot.
14. Which of the following are considered greenhouse
gases?
Ans: carbon dioxide and methane
15. Which kind of plate boundary produced the Himalayas?
Ans: Two plates pushed into each other to push the land upward
and generate a mountain range.
16. Greenhouse gases in Earth's atmosphere
Ans: absorb infrared radiation emitted by the ground.
17. After absorbing incoming solar radiation, Earth emits
mostly __________, which is the radiation associated with
heat. Ans: infrared radiation
18. The greenhouse effect __________.
Ans: helps keep Earth's surface sufficiently warm for life to exist
19. The greenhouse effect occurs because greenhouse
gases __________.
Ans: - absorb infrared radiation emitted by the surface
, 20. If more water vapor was present in Earth's
atmosphere, what would happen to Earth's temperature?
Ans: The temperature would increase.
21. The most abundant greenhouse gas in volcanic
eruptions is __________.
Ans: water vapor
22. Solar radiation __________.
Ans: has been increasing over the past several billion years
23. Which of the following is a natural process that adds
carbon dioxide to the atmosphere? Ans: respiration
24. Plants remove carbon dioxide from the atmosphere
and cutting down forests
Ans: increases the rate of global warming.
25. If the mass of the box increases, but the force remains
the same, the box's acceleration will Ans: decrease
26. Why does San Francisco have earthquakes?
Ans: San Francisco lies along the boundary between the North
American plate and the Pacific plate. At this location, they are
grinding past each other, occasionally slipping suddenly along a
transform fault.
27. If the mass of an object increases,
Ans: a given force will produce less acceleration.
28. When force increases Ans: acceleration also increases,
according to Newton's second law.
29. The net force acting on an object moving in a straight
line at a constant speed Ans: is zero
30. Friction is the force that Ans: opposes motion of an
object
