At the time, there was no way to prove that a massive supercontinent had ever existed, and the idea that continents could move through the ocean floor seemed preposterous.
He was a heavy smoker and died of heart failure. Ocean floor exploration continued, and by the s other researchers had found that a huge rift ran along the top of the Mid-Atlantic Ridge.
As well, he had always dreamed of polar exploration. It was discovered that earthquakes were abundant along the ridges that let magma flow from them. An earlier version of this article misstated the length of the Mid-Atlantic Ridge.
Scientists can only guess when the first plates formed and how they behaved further back than that. That enabled Hess to understand his ocean floor profiles in the Pacific. If we come to a better understanding of plate tectonics, the evolution of different species of animals will become clearer to us.
Six years later he led another expedition to Greenland, this time with government backing, where he would set up yearlong weather-monitoring equipment at three stations on the glacier.
Article shared by Numerous studies, even in recent years, confirm the theory that the great continental mass pushed out of the sea in the earlier periods and then split apart into several pieces which drifted about the Earth for hundreds of millions of years.
These fossils were also found on the coast of South America and Africa suggesting they had been joined together at these edges. Continental drift explains how the rocks in one area of the worldcould be the same as the rocks in another separate area, and whywidely-separated areas shared the same biological histories.
The Triassic period, - million years ago The Jurassic Period, million years ago The Cretaceous Period, million years ago. Geology term papers Disclaimer: The mantle is solid in the short term, but flows very slowly over geologic timescales.
Today similar species inhabit these once connected continents such as certain marsupial and monotreme species in Australia, Antarctica and South America. But all these ideas were mostly ignored and soon forgotten since virtually everyone believed the continents were firmly fixed throughout geological time.
Share your thoughts in the Questions Area below!Alfred Wegener, being a meteorologist, had proposed tidal forces and centrifugal forces as the main driving mechanisms behind continental drift; however, these forces were considered far too small to cause continental motion as the concept was of continents plowing through oceanic crust.
Inthe German geologist and meteorologist Alfred Wegener first proposed the theory of continental drift, which states that parts of the Earth's crust slowly drift atop a liquid core. The fossil record supports and gives credence to the theories of continental drift and plate tectonics.
