CONTINENTAL DRIFT


CONTINENTAL DRIFT

According to Alfred Wegener, the entire landmass of the globe was together about 280 million years ago.

It was termed as Pangea, a super continent.

The huge water body surrounding the Pangea was known as Panthalasa.

From 280 to 150 million years ago, Pangea was broken latitudinally into northern and southern parts known as Laurasia (Angaraland) and Gondwanaland, respectively.

Both of them drifted away and in between a shallow sea emerged by filling up the water from Panthalasa. It was known as Tethys Sea.

Later on Laurasia and Gondwanaland rifted and finally drifted to form the present day distribution of land and water on the earth.
