Question

Quizplus · Accepted Answer

The atmospheric gas on Mars, primarily carbon dioxide, solidifies on one of the polar caps during certain seasons, leading to a drop in barometric pressure. This is a seasonal phenomenon related to the extreme temperature variations on Mars, where carbon dioxide can freeze out of the atmosphere onto the polar caps, especially during the Martian winter.
