- B. Mountains can cause heavy rain on one side and dry conditions on the other (a rain shadow).
- C. Ocean currents only move water, not heat.
- D. Ocean currents move heat around the planet.
Question 7
What does the greenhouse effect do?
- A. It makes holes in the atmosphere
- B. It reflects all sunlight back to space

Question 12
Global climate: which statement is NOT true?
- A. The poles are cold because they are farther from the Sun.
- B. Warm air rises and cooler air sinks.
- C. Earth's rotation deflects winds (the Coriolis effect).
- D. Mountains can cause heavy rain on one side and dry conditions on the other (a rain shadow).
Question 13
Which is an effect of climate change?

- C. the Earth stopping rotating
- D. the end of all weather
Question 14
Climate change: which statement is NOT true?

Answer%
Question 16
What causes global wind patterns such as the trade winds?

- B. The Moon pulls the air
- C. Mountains blow the air
- D. Ocean waves push the air
