Question

It is theorized that the continents on Earth were once joined together,

forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences

Answer 1

Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.

During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.

One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.

The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.

Answer 2

Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
