Study Guide
1. Surface currents are controlled by global winds, the Coriolis Effect, and continental
deflections.
2. The wind is caused by differences in air pressure.
3. What happens to most of the solar energy that reaches Earth’s atmosphere? It is
absorbed by the land and ocean
4. The density of the ocean water increases when its temperature decreases
5. What happens to a surface current when it deflects a continent? It changes directions
6. Convection is the transfer of energy by the circulation of gases or liquids.
7. What causes differences in air pressure around the Earth? Warm air rises at the
equator, and cold air sinks at the poles.
8. What causes water from deep currents to rise to the surface to replace warm currents?
the flow of warm currents from the equator toward the poles
9. The Earth’s Rotation causes the curved paths of global winds and surface currents.
10. Wind occurs because of differences in air pressure.
11. Why does warm air rise and cold air sink? Warm air is less dense than cold air which
makes it rise. Cold air is more dense which makes it sink
12. Convection is the method by which most thermal circulates in the atmosphere.
13. Ocean currents flow from east to west near the equator.
14. Wind formation occurs when solar energy-warm air rises, then air cools in the upper
atmosphere and sinks=air currents.
15. What best describes the wind? Moving air-caused by differences in air pressure when
the atmosphere is warmed by the sun. The greater the pressure difference the faster
the wind moves.
16. What is a renewable resource of energy that drives the wind? Sun
17. Air is warmer and less dense than surrounding air at the equator because the equator
receives more solar energy.
