On the basis of all these factors, it may be assumed that the Americas were joined with Europe and Africa until approximately 190 million years ago, when a rift split them apart along what is now the crest of the Mid-Atlantic Ridge. Wegener supported his theory by demonstrating the biological and geological similarities between continents. Indications of widespread glaciation from 380 to 250 million years ago are evident in Antarctica, southern South America, southern Africa, India, and Australia. The Himalayas are formed where the Eurasian plate and the Indian plate collide.

They based their idea of continental drift on several lines of evidence: fit of the continents paleoclimate indicators truncated geologic features and fossils. However, further work showed that the polar wandering curves are different for the various continents. This is called Ridge Push. As we travel further from the mid Atlantic ridge we can see the alignment changing which proves the continents have been moving away from each other. 3.

The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. The present continents appear to fit together as pieces of a larger landmass. The continents shapes fit well together and some continents have the same fossils. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea. Temperature and pressure both increase with depth. Fossils tell us when and where plants and animals once existed. The plates continue to move apart at the speed that our fingernails grow.
