Why Is the Energy of the Sun Less Intense at the Poles

question 70

Multiple Choice

Why is the energy of the sun less intense at the poles as compared to the equator?

• A) The tilt of the earth moves the poles farther away from the most intense sunlight.
• B) Because the earth is spherical and the sun shines toward the equator the sunlight is more spread out at the poles and therefore less intense.
• C) The movement of wind across the face of the earth pulls cooler air from over the oceans and blows it toward the poles. This cools the poles while leaving the region around the equator hot.
• D) The movement of cool waters in ocean currents flows away from the equator and cools the air farther from the equator causing the polar regions to be cooler than the equatorial region.
• E) The earth shifts in its orbit periodically and at times it moves farther from the sun. This movement coincides with times that the earth is tilted toward the sun so the poles never receive as much sunlight as the equator.
