Question
Alfred Wegener suggested that a supercontinent he called Pangaea had existed in the past, broke up starting about 240 million years ago, and that the pieces ``drifted'' to their present positions. He cited the fit of South America and Africa, ancient climate similarities, fossil evidence, and similarity of rock structures.
b. Explain how mountain chains provided evidence for the existence of Pangaea.
c. Explain how fossils provided evidence for the existence of Pangaea.
d. Explain why India has evidence of glaciers that are >240 million years old even though it is located on the equator.
Explanation / Answer
Answer 1. They provide evidence for the existence of Pangaea because the Mountain belts along the margins of North America, Africa and Europe line up as well and have similar rock types. This indicates that the continents at one time were joined as the Pangaea. It also indicate that there was continental drift.
Answer 2. Fossils provided evidence for the existence of Pangaea as early plants and animals species were found across continents supporting the evidence of Pangaea . The Pangaea implies that at some part in the Earth's evolution, probably before the rise of mammals there was one major world continent that since has split up into the present seven. As life of intelligent type did not exist at the time, thus it is not possible that fossils can be dragged in to prove things one way or the other, though it does have a relative bearing on Atlantis and Atlantean studies.
Answer 3. India has evidence of these glaciers because of the existence of Pangea. Scientists believe that India was Connected to the South Pole ie India wasn't always near the equator. Earlier India was its own continent before crashing into Asia, creating the Himalayas. As the South pole is very cold so India also has the presence of glaciers on it.
