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 is the best definition for continental drift?
Definition of continental drift : a slow movement of the continents on a deep-seated viscous zone within the earth — compare plate tectonics.
How do you explain continental drift?
Continental drift is the hypothesis that the Earth’s continents have moved over geologic time relative to each other, thus appearing to have “drifted” across the ocean bed. The speculation that continents might have ‘drifted’ was first put forward by Abraham Ortelius in 1596.
What does continental drift mean for kids?
Continental Drift The plates have moved across Earth’s surface for hundreds of millions of years. As the plates move, the continents on them move, too. This movement is called continental drift. Pangea lay across a plate boundary. Slowly, Pangea broke apart at this boundary.
What are examples of continental drift?
The Appalachians of the eastern United States and Canada, for example, are just like mountain ranges in eastern Greenland, Ireland, Great Britain, and Norway. Wegener concluded that they formed as a single mountain range that was separated as the continents drifted.
What’s another word for continental drift?
Noun Phrase Plate tectonics is significant because it explains how continental drift can occur.
What is continental drift ks3?
Continental drift is a historical, scientific theory. The theory was first proposed by Abraham Ortelius in 1596. It was fully developed by the German geologist and meteorologist Alfred Wegener in 1915. The theory said that parts of the Earth’s crust move slowly on top of a liquid mantle of higher density.
Why did scientists reject Wegener’s theory?
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.
Who is the father of continental drift?
Alfred Wegener
Alfred Wegener: The Father of Continental Drift.
What is the main idea of continental drift?
Continental drift. The idea of continental drift has been subsumed by the theory of plate tectonics, which explains that the continents move by riding on plates of the Earth’s crust.
What does continental drift indicate about the Earth?
(Image credit: USGS) 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 is meant by continental drift?
Continental drift. Continental drift is the movement of the Earth’s continents relative to each other by appearing to drift across the ocean bed.
Which terms describes continental drift?
Continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time. This concept was an important precursor to the development of the theory of plate tectonics, which incorporates it.
