Look at the map that shows the continents 200 million years ago. Based on the map, which continent would be the most likely to have rock sequences and ages similar to those shown in Africa and South America? Explain why.

Answer 1

To determine which continent would have rock sequences and ages similar to those of Africa and South America based on a map from 200 million years ago, we need to consider the concept of continental drift and the configuration of continents during the late Paleozoic and early Mesozoic eras.

Around 200 million years ago, the continents were in different positions than they are today due to the process of plate tectonics. At this time, the continents were part of the supercontinent Pangaea. This configuration means that landmasses that are currently far apart would have been connected.

Africa and South America share significant geological features and rock formations, which is evidence of their connection in the past. The most apparent similarity arises from the continuity of the geological structures and fossils found in both continents. In fact, they are often referred to as reflection of a formerly continuous land area known as "Gondwana."

Given this context, the most likely continent with rock sequences and ages similar to those found in Africa and South America would be Antarctica. Around 200 million years ago, Antarctica was positioned directly south of Africa and South America, and they were all part of the Gondwana supercontinent. Therefore, the rock sequences and ages found in Antarctica would exhibit similarities due to their shared geological history.

In summary, Antarctica would likely have rock sequences and ages similar to those of Africa and South America because they were all physically connected as part of Gondwana during the time period in question.
