Question

Quizplus · Accepted Answer

All three options are correct. The Martian polar ice caps are made up of a combination of water ice and frozen carbon dioxide, unlike the Antarctic ice cap, which is made up of only water ice. The Martian ice caps also have a unique spiral fracture pattern not found in Antarctica. Additionally, the ablation (melting) of the Martian ice caps is caused by sublimation (transformation from solid to gas) only, as there is currently no liquid water on the surface of Mars.
