Why is antarctica colder then Atlantic?

Answer 1

The Antarctic region is much colder than the Atlantic region for two main reasons:

1. The Antarctic receives a lot less sunlight. The earth's axis is on a tilt, which causes seasons as the earth travels around the sun. During the antarctic winter, much of the region goes without sunlight for many months at a time.

2. The Antarctic region is at a very low angle relative to the sun's light. The equator receives the sun's light at about a 90 degree angle, or straight on. This means the full force of the light hits the surface of the earth. At the poles however, the low angle means the light hits the surface of the earth with much less intensity, so what little sunlight the Arctic gets isn't very strong.
