• Continental drift theory, given by Alfred Wegner in 1912, suggests that all the continents are formed from a single continental mass ‘namely PANGAEA’ surrounded by mega ocean ‘namely PANTHALASSA’.
• He argued that around 200 million years ago PANGAEA broke into various continents.

Evidences in support of the continental drift theory:-

The Jig-Saw-Fit (matching of continents):-

The shorelines of South America and Africa facing each other have remarkable and unmistakable match.

The rocks of same age across the oceans:-

radiometric dating methods have correlated the rock formation in different continents.

eg- marine deposits along the coastline of south america and africa are of the Jurassic age.

Tillite: 

The glacial tillite found in Gondwana system of sediments has its resemblance to six different landmasses of the Southern Hemisphere.

Placer Deposits: 

The placer deposits of gold in the Ghana coast do not have source rock in the region.

Distribution of Fossils: 

identical species of plants and animals adapted to living on land or in freshwater are found on either side of the marine barriers.

END:-

The Continental Drift Theory had some limitations they are mentioned below:

• Wegener was unable to clarify why the drift started.
• the forces described by wegner that propelled the movement of continents were, too weak to move continents.
