What evidence was missing from continental drift?

What evidence was missing from continental drift?

Portrayal of thermal convection as a mechanism. The main issue with Wegener’s Continental Drift Theory was he did not have a mechanism behind the drifting of continents.

Why was continental drift not accepted?

The main reason that Wegener’s hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth’s spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

What is the evidence for the continental drift theory?

Another important piece of evidence in the Continental Drift theory is the fossil relevance. There are various examples of fossils found on separate continents and in no other regions.

What did Wegener’s continental drift theory say about Pangaea?

According to Wegener’s Continental Drift Theory, there existed one big landmass which he called Pangaea which was covered by one big ocean called Panthalassa. A sea called Tethys divided the Pangaea into two huge landmasses: Laurentia (Laurasia) to the north and Gondwanaland to the south of Tethys.

How is the equator ward related to continental drift?

Force for Continental Drift. equator wards due to the interaction of forces of gravity, pole-fleeing force and buoyancy (ship floats in water due to buoyant force offered by water), and westwards due to tidal currents because of the earth’s motion (earth rotates form west to east, so tidal currents act from east to west.

When did the continents begin to drift away from one another?

Drift started around 200 million years ago (Mesozoic Era, Triassic Period, Late Triassic Epoch), and the continents began to break up and drift away from one another. Watch the video for quick and better understanding If playback doesn’t begin shortly, try restarting your device.
