What is the evidence of continental drift theory?

By Ritesh|Updated : September 1st, 2022

The evidence of continental drift theory is - the matching of continents, rocks of the same age across oceans, tillite, placer deposits, and fossil distribution. The fossil record is one sort of evidence that has been used to support the Theory of Continental Drift.

Evidence of Continental Drift Theory

On the coastlines of continents, fossils of similar plants and animals have been discovered, indicating they were connected. The following provides support for the notion of continental drift:

The Matching of Continents:

The shorelines of South America and Africa are perfectly aligned with one another.

Boulders of the Same Age Across the Oceans:

A belt of 2,000 million-year-old rocks off the coast of Brazil matches those in western Africa.

Tillite:

  • There are known equivalents of the Indian Gondwana system of deposits in six distinct Southern Hemisphere landmasses.
  • Along with India, the Falkland Islands, Madagascar, Antarctica, and Australia also have counterparts in this succession.

Placer deposits:

  • Rich gold placer deposits can be found along Ghana's coast.
  • However, the area lacks a source rock.
  • When the two continents are placed side by side, it is evident that the gold reserves in Ghana are derived from the Brazil plateau due to the gold-bearing veins there.

Distribution of Fossils:

On either side of the marine barriers, identical species of plants and animals that can live on land or in freshwater can be found.

Summary:

What is the evidence of continental drift theory?

The evidence of continental drift theory is - rocks of the same age across oceans, matching continents, placer deposits, tillite, and fossil distribution.
