1. Global climate is determined _________.


A. completely by greenhouse gas emissions from human activities.


B. by clouds reflecting all of the Sun's energy back into space.


C. by the transfer of solar energy at and near the Earth's surface.


D. by solar energy interacting with land but not water.

2.Convection currents, resulting from uneven heating of the Earth's surface, cause _______ to form.


A. fossils


B. mountains


C. wind


D. volcanoes

3. Winds generally flow away from the equator and towards the poles. What transfer does this flow of wind cause?


A. an energy transfer, with heat energy moving away from the equator

B. a water transfer, with water moving from the atmosphere to the ocean


C. a water transfer, with water moving from the ocean to the atmosphere


D. an energy transfer, with heat energy moving toward the equator

4. Areas of the Earth near the equator receive large amounts of solar energy. How does this lead to increased rainfall?



A. The solar energy heats the air, which causes water vapor to condense.


B. The solar energy provides the energy for water to evaporate.


C. The solar energy allows plants to complete photosynthesis reactions.


D. The solar energy creates wind, which pushes clouds from the poles to the equator.
