7. 6. The deflection of an object's path due to Earth's rotation is called a) Hadley cells b) El Niño–Southern Oscillation c) the albedo effect d) the Coriolis effect e) The rainshadow effect

8. 7. Which of the following statements of cause and effect is false?
a)differential in solar energy striking the equator versus the poles sets up general global air circulation patterns.
b) The earth's rotation is faster under air at the poles causes the prevailing winds.
The earth's rotational tilt and revolution around the sun cause seasonal variations in temperature.
The earth's rotation, the inclination of the earth's axis, prevailing winds, and differences in water density cause ocean currents.
e) Heat from the sun evaporates ocean water and transfers heat from the oceans to the atmosphere.

9. 8. The most probable chain of cause and effect contributing to patterns of earth's biomes is
a) Incoming solar energy and the earth's geometry create climate patterns which create air and ocean currents that create biome patterns.
b) Incoming solar energy and the earth's geometry create air and ocean currents that create climate patterns that create biome patterns.
c) Incoming solar energy and the earth's geometry create climate patterns that create biome patterns that create air and ocean currents.
d) Air and ocean currents determine incoming solar energy and the earth's geometry which create climate patterns that create biome patterns.
e) Air and ocean currents determine incoming solar energy that create climate patterns which create biome patterns.
