Which of the following paleoclimatic evidence supports the idea of the late Paleozoic supercontinent in the Southern Hemisphere?
A) lithified loess (wind-blown) deposits in the deserts of Chile, Australia, and Africa
B) tillites (rocks formed by glaciers) in South Africa and South America
C) thick sediments in the Amazon and Congo deltas of South America and Africa
D) cold water fossils in the deep-water sediments of the South Atlantic abyssal plain

Question

Quizplus · Accepted Answer

Tillites are rocks formed from glacial deposits, indicating that these regions were once covered in glaciers, which supports the idea of a supercontinent because such conditions are more likely to occur in a landmass at high latitudes. Lithified loess deposits indicate wind activity, but they do not necessarily support the idea of a supercontinent. Thick sediments in the Amazon and Congo deltas indicate large river systems, which could exist on any continent. Cold water fossils in deep-water sediments do not indicate the presence of a supercontinent, only that the water in the region was cold at that time.
