ANALYZE the map. The white areas show the location of glacial grooves.Explain The discovery of glacial grooves in Africa is surprising because much of Africa is warm today. How does the hypothesis of continental drift help to explain these glacial features?
a)Africa is too warm to have glaciers today. The glacial grooves pattern suggest that either the South pole had moved sometime in the geologic past, or that Africa had once been closer to the South pole.
b)Africa is reliable to have glaciers today. The glacial grooves pattern suggest that either the South pole had moved in the geologic past, or that Africa had once been away from the South pole.
c)Africa is too warm to have glaciers today. The glacial grooves pattern suggest that either the north pole had moved sometime in the geologic past, or that Africa had once been closer to the north pole.
