GEOLOGY

Detailed explanation-1: -Wegener called this ancient continent Pangaea. Other scientists had proposed such a continent but had explained the separation of the modern world’s continents as having resulted from the subsidence, or sinking, of large portions of the supercontinent to form the Atlantic and Indian oceans.

Detailed explanation-2: -From about 300-200 million years ago (late Paleozoic Era until the very late Triassic), the continent we now know as North America was contiguous with Africa, South America, and Europe. They all existed as a single continent called Pangea.

Detailed explanation-3: -Pangea, the supercontinent For Wegener this was only possible if the current continents were once concentrated around the equator forming a supercontinent, which broke apart some 200 million years ago and which he called Pangaea.

Detailed explanation-4: -In 1912, German scientist Alfred Wegener proposed that Earth’s continents once formed a single, giant landmass, called Pangaea. Over millions of years, Pangaea slowly broke apart, eventually forming the continents as they are today.
