Answer to Question 1

Answer: During the Paleozoic, the present-day continents of Africa, Australia, Antarctica, South America, New Zealand, India, and southeastern Asia moved across the South Pole. In late Paleozoic time, these continents collided with North America and Eurasia to form Pangaea. Throughout this time the southern continents experienced cyclic episodes of glaciation. During warmer interglacial stages, Glossopteris and other plants tolerant of the cool, damp climate, flourished and provided the materials for thick seams of coal.
