Explanation: … … As the asthenosphere is plastic, the lithosphere … This provides much of the energy for the processes that move the plates, resulting in continental drift. Continental drift was a revolutionary scientific theory developed in the years 1908-1912 by Alfred Wegener (1880-1930), a German meteorologist, climatologist, and geophysicist, that put forth the hypothesis that the continents had all originally been a part of one enormous landmass or supercontinent about 240 million years ago before breaking apart and drifting to … What countries were once "together"?

In this map depicting a portion of Gondwana (an ancient supercontinent that once contained South America, Africa, Australia, India, and Antarctica), the discovery of fossil plants and animals whose geographic home ranges cut across the greater landmass is supporting evidence for continental drift.
