What did the theory of continental drift suggest?

What did the theory of continental drift suggest?

Continental drift describes one of the earliest ways geologists thought continents moved over time. In the early 20th century, Wegener published a paper explaining his theory that the continental landmasses were “drifting” across the Earth, sometimes plowing through oceans and into each other.

When the continental drift theory was suggested?

The first truly detailed and comprehensive theory of continental drift was proposed in 1912 by Alfred Wegener, a German meteorologist. Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea.

What did Alfred Wegener suggest about the theory of continental drift in 1915?

Alfred Wegener suggested that continental drift occurred as continents cut through the ocean floor, in the same way as this icebreaker plows through sea ice. Wegener put his idea and his evidence together in his book The Origin of Continents and Oceans, first published in 1915.

What theory was developed in the 1960s that explain his ideas?

The fact that in the 1960s the tectonic plate theory was accepted and, having this theory, similar ideas to those stated by Wegener in 1912, made scientific community consider him the father of the continental drift theory.

When did continental drift happen?

1912
Continental drift was a theory that explained how continents shift position on Earth’s surface. Set forth in 1912 by Alfred Wegener, a geophysicist and meteorologist, continental drift also explained why look-alike animal and plant fossils, and similar rock formations, are found on different continents.

What did Wegener use to support the continental drift hypothesis?

Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator.

What observation led Alfred Wegener’s theory of continental drift hypothesis?

Wegener also noticed that if you could shove western Europe and Africa together with North and South America, their coastlines would fit together very neatly. All this evidence led Wegener to believe that the continents were once connected but had separated and drifted apart.

What is continental drift theory and what are the evidences that support it?

In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.

Which theory supports the idea of continental drift?

The continental drift theory is the theory that once all the continents were joined in a super-continent, which scientists call Pangaea. Over a vast period of time, the continents drifted apart to their current locations. Alfred Wegener first supported continental drift.

What is the evidence that support continental drift theory?

Continental Drift – Evidence. The evidence which gave rise to the theory of continental drift — more correctly called plate tectonics — includes the following: The coasts of the continents surrounding the Atlantic ocean could, if the continents were moved closer, fit together like a jigsaw puzzle.

What were problems with the theory of continental drift?

The theory of continental drift was not accepted for many years. One problem was that a plausible driving force was missing. A second problem was that Wegener’s estimate of the speed of continental motion, 250 cm/year, was implausibly high.

Why was the theory of continental drift not accepted first?

The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities.
