Question

Which is the best evidence that Earth's continents were once in different parts?

A. Asia has a wet and warm climate.
B. Africa and South America have rainforests.
C. Volcanoes are located around the Pacific Ocean.
D. Australia and Antarctica have similar dinosaur fossils.
E. Penguins are found only in the Southern Hemisphere.

Answer 1

The presence of similar dinosaur fossils in Australia and Antarctica is the best evidence that Earth's continents were once connected, supporting the theory of continental drift.

Step-by-step explanation:

The best evidence that Earth's continents were once in various parts is D. Australia and Antarctica have similar dinosaur fossils. This suggests that these two continents were once joined, enabling dinosaurs to inhabit both regions before they were separated by tectonic movements. The matching fossil evidence supports the theory of continental drift, which posits that the continents were once united in a supercontinent called Pangea and have since drifted to their current positions. It's part of a larger field of study known as plate tectonics, explaining the movement of Earth's lithospheric plates and the changes in geographical configurations over geological time.
