Continental drift is the gradual movement of the continents over time. The top layer of the earth’s crust is broken up into large slabs called plates that sit on a fluid level of molten rock. The movement of this lower molten layer causes the plates to shift. This movement, also called ...
But this would change, because in the same period of geologic time there was a shift in the earth's continental plates. Continental drift caused Antarctica to move apart from the landmass of South America and to drift into the Southern Polar Region. This resulted in a powerful water current ...
How do fossils provide evidence for the theory of continental drift? Which answer choice is mismatched between geologic period and event? Select one: a. Carboniferous - coal-forming forests. b. Jurassic - flowering plants appear. c. Ordovician - nonvascular plants appear on land. d. Devonian -...
The theory of plate tectonics is the foundation of modern geology that merges the concept of continental drift and seafloor extension together to explain the positions of the continents and the past similarities geologically of the continents, although they are very divergent now in their nature....
The whole idea of plate tectonics is a more advanced version of an idea developed in the early 1900s called continental drift. During that time, ascientistnamed Alfred Wegener decided to investigate some obvious facts that he found curious about the way the Earth was put together. There were ...
Pangaea or Pangea was first proposed by Alfred Wegener in 1912, using fossil evidence to back up his hypothesis of a supercontinent. The name comes from pan or whole and Gaia or Mother Earth. Continental Drift: The continents of the Earth slowly move around due to the convection currents in...
The theory of plate tectonics was developed from the 1950s to the 1970s. It is the modern update tocontinental drift, an idea first proposed by scientist Alfred Wegener in 1912, who that Earth’s continents had "drifted" across the planet over time. Wegener didn't have an explanation for...
Interestingly enough, you must not have read all the way through the article Dayton. "A forerunner of plate tectonics was the theory of continental drift, put forth in 1912 by German meteorologist, Alfred Lothar Wegener." Dietz and Hess did not "develop" the theory, they expanded upon an al...
