Solutions to Physical Science Question
1. Explain how the temperature difference between the poles and the equator drives the motion of the oceans and atmosphere.
Solution
Since cold air is denser than warm air, temperature differences give rise to atmospheric motions, and those motions work to eliminate the differences. Winds move warm, moist air upward and poleward from the tropical surface and move cold, dry air downward and toward the equator from higher altitudes and latitudes. The contrasts in heating, together with the winds, also drive ocean currents (as a result of differences in density), which help reduce temperature differences between the equator and the poles even more.
2. What are the differences between ice caps and glaciers?
Solution
Ice caps are thick layers of ice and snow that cover large areas of land. They are stagnant in nature (they do not move). Glaciers on the other hand are huge mass of ice slowly flowing over a land mass. Thus the difference between the two is that the bodies of ice in ice caps are stagnant while that of glaciers are in motion (they move).
3. How do ocean currents affect local climate?
Solution
Ocean currents affect local climate through energy heat transfer. Through heat transfer the cold currents cool off the warm ...
