Question

The presence of Late Paleozoic-age glacier-formed sedimentary rocks in southern Africa, southern South America, India, and Australia suggest that

1. these landmasses existed at significantly higher overall elevations during the Late Paleozoic
2. these landmasses existed closer to the south pole during the Late Paleozoic
3. water froze at higher temperatures during the Late Paleozoic
4. these landmasses experienced an intensive period of comet bombardment during the Late Paleozoic that cooled the Earth's crust there
5. cloud cover over these landmasses must have been much heavier during the Late Paleozoic, cooling the temperatures there

Answer 1

The presence of glacier-formed sedimentary rocks in southern Africa, southern South America, India, and Australia suggests that these landmasses were closer to the south pole during the Late Paleozoic.

Step-by-step explanation:

The presence of late Paleozoic-age glacier-formed sedimentary rocks in southern Africa, southern South America, India, and Australia suggests that these landmasses existed closer to the south pole during the Late Paleozoic.

During the Paleozoic Era, the distribution of landmasses on Earth was very different. At that time, there were two large supercontinents near the equator: Laurentia and Gondwana. As the Paleozoic progressed, the landmasses began moving together and eventually formed the supercontinent called Pangaea. Glaciations then affected Pangaea's climate and the distribution of vertebrate life.

The presence of glacier-formed sedimentary rocks in these regions provides evidence of past glaciations and suggests that they were closer to the south pole during the Late Paleozoic.
