Question

which of the following best describes how ice once covered warm places such as australia a
a) their climates changed over time.
b) their elevations used to be higher.
c) they were once closer to the south pole.
d) they were once all connected to each oth

Explanation:

Ice sheets form in cold, polar or near-polar regions. The theory of continental drift (plate tectonics) explains that continents move over geological time. Australia, now in a warm, temperate/subtropical zone, was part of the supercontinent Gondwana and was positioned much closer to the South Pole in the past, leading to glaciation there. Climate change alone does not fully explain the presence of ancient ice in currently warm continental interiors, higher elevation would not create widespread continental glaciation across Australia, and continental connection does not directly cause glaciation unless the land is in a cold polar region.

Answer:

C. They were once closer to the South Pole.
