Which polar cap on Mars is larger and colder?
Mars Polar Cap
The southern polar cap is larger and colder. It is composed of
carbon dioxide (dry ice) while the northern is mainly water ice
(which freezes at a warmer temperature, therefore the dry ice cap
in the south is colder).

What is a polar ice cap?
A polar ice cap is the layer of ice at the polar regions of a planet. On earth this is at the North and South poles. An ice cap does not have to be on land, so our Arctic ice cap floats on water, and our Antarctic ice cap covers the continent of Antarctica. The Greenland ice cap is not a polar ice cap.
