It is generally warmer near the equator than it is near the poles because

• near the poles, sunlight hits at an angle where it spreads over a

  large area.

• sunlight hits Earth’s surface most directly near the poles.

• when sunlight hits the equator, it is spread out over a greater area and cools.

• eclipses most often occur over the poles, preventing sunlight from hitting the polar areas.
