Oct 19, 2023 · Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics.
Jun 14, 2024 · Continental drift, large-scale horizontal movement 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.
Continental drift is the hypothesis, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time.

Mar 7, 2024 · In the early 20th century, a scientific theory called continental drift was proposed about this migration of the continents. That theory was initially ridiculed, but it paved the way for another theory called plate tectonics that scientists have now accepted to explain how Earth’s continents move.
The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent.

Continental drift. During the 20th Century, scientists developed the theory of Plate Tectonics. The theory suggests that the crust of the Earth is split up into seven large plates (see map below) and a few smaller ones, all of which can slowly move around on the Earth’s surface.
May 24, 2024 · The movement of lithospheric plates referred to as continental drift, is believed to be caused by the radioactive decay of elements in the core and mantle that produces heat. The heat in turn creates convection currents in the mantle which "drive" the plates along their path of movement.
continental drift, Large-scale movements of continents over the course of geologic time. The first complete theory of continental drift was proposed in 1912 by Alfred Wegener, who postulated that a single supercontinent, which he called Pangea , fragmented late in the Triassic Period (approximately 250–200 million years ago) and that the ...
