What was Wegener's dramatic paleoclimatic evidence linking all of the southern hemisphere continents between 300 and 220 million years ago?
A)massive crossbedded red sandstones suggesting former tropical deserts
B)massive reef limestones in Alberta and the Eastern Arctic
C)tropical Carboniferous coal swamps across the Northern Hemisphere, particularly the Eastern U.S.and central Europe, where the fossil trees lacked annual growth rings
D)striated and grooved bedrock overlain by Paleozoic tillites in South American and African areas now within 30° of the equator

Question

Quizplus · Accepted Answer

Wegener pointed out that the distribution of Paleozoic glacial deposits, tillites, and striated bedrock in South America and Africa indicates that they were joined as a single continent during the Permian period, around 300-220 million years ago. These cold-climate rocks are now found in areas close to the equator, implying that the continents were together in high southern latitudes during this period.
