Question

What was the climate like in Antarctica before humans arrived on the global scene?

Answer 1

The climate in Antarctica before humans arrived was much warmer, and it hosted a wide variety of flora and fauna, as indicated in the passage. The description highlights that the environment was significantly different from today’s cold conditions, emphasizing a richer and more diverse ecosystem.

Answer 2

Gondwana existed nearly 500 million years ago, according to the passage. The text explicitly mentions that Gondwana thrived for 500 million years before the landmass separated into distinct continents.

Answer 3

The correct answer is (A) complexity of geological processes. The passage describes the significant changes Gondwana underwent, separating into multiple countries. This suggests complex geological processes at play, particularly the shifting and dividing of landmasses over time.

Answer 4

The author highlights that the main difference between then and now is the arrival of humans and the subsequent cooling of the climate. The passage contrasts the warmer climate and diverse flora and fauna of Gondwana with the present-day condition of Antarctica, which is cold and largely devoid of life.
