Just took the test and figured out the answer was A. Hoped I helped you and everyone else reading this.
Answer:
The Earth rotates about an imaginary axis that passes two different poles. ... So, the equator experience more angular speed that tries to pull off the part of the Earth from the rotational axis. Hence the equator of the Earth is wider and bulge. The rotation of the Earth about its own axis affects the shape of the Earth.
It would be letter A which is energy. The other three are used in weather forecasting due to the fact that the atmosphere is fluid and weather and climate is caused by uneven heat from the star in our solar system which is the Sun to the Earth in which heat transfer occurs
Incoming solar radiation is almost double at the equator then at the poles, causing the water closer to the equator to be warmer. The heat difference also causes the oceans to swirl so the water that is around the equator will eventually end up at the poles and keep circulating around.
Probably right on the equator. Tropical or whatever is on the equator.
