Question

What causes the seasonal change in size of the Martian polar caps? During what season would the largest amount of dry ice be present at the polar cap?

Answer 1

Answer:

"

Martian atmosphere exists on Mars. It has bright polar caps where there are dramatic climatic changes. During the winter season, the cap becomes larger because the carbon dioxide freezes on the surface. It happens because the temperature plummets up to 150K.

In the summer season, the caps recede but don’t disappear. The permanent cap at the Martian north pole is formed of ordinary water. Unlike earth, the CO2 on Mars is not in the gaseous state, rather it condenses.

Mars rotates around a tilted axis, which brings more warmth from the Sun to the northern hemisphere than the Southern hemisphere. The polar CO2 caps grow and shrink accordingly.
