  1. Continental drift is the theory, originating in the early 20th century, that Earth's continents move or drift relative to each other over geologic time. [1] The theory of continental drift has since been validated and incorporated into the science of plate tectonics , which studies the movement of the continents as they ride on plates of the ...

  2. Sep 16, 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.

    According to plate tectonic theory, the Earth’s surface is made up of slabs of rock that are slowly shifting right under our feet. Because of this constant movement, today’s Earth looks a lot different from what it did millions of years ago. Today’s animation looks at the Earth’s tectonic plate movement from 1 ga (geological time for 1 billion year...

    Plate tectonics is a relatively new theory—in fact, according to National Geographic, it hadn’t become popular until the 1960s. However, the concept of continental movement was brewing long before it became widely accepted. In 1912, German scientist Alfred Wegener proposed a theory he called continental drift. According to Wegener’s theory, Earth’s...

    Nowadays, it’s believed that Pangea was just one of several supercontinents to mass together (and break apart) over the course of geological history. The exact number of supercontinents is largely debated, but according to the Encylopedia of Geology, here are five (including Pangea) that are widely recognized: 1. Kenorland: 2.7-2.5 billion years ag...

    Plate tectonics has been a game-changer for geologists. The theory has helped to explain tons of unanswered geological questions, assisting scientists in understanding how volcanoes, mountains, and ocean ridges are formed. It’s also valuable for the oil and gas industry since it explains how sedimentary basins were created, allowing geologists and ...

  3. Dec 14, 2021 · Continental drift was a revolutionary theory explaining that continents shift position on Earth's surface. The theory was proposed by geophysicist and meteorologist Alfred Wegener in 1912, but...

  4. Jul 24, 2019 · Continental drift was a revolutionary scientific theory developed in the years 1908-1912 by Alfred Wegener (1880-1930), a German meteorologist, climatologist, and geophysicist, that put forth the hypothesis that the continents had all originally been a part of one enormous landmass or supercontinent about 240 million years ago before breaking ...

  5. Aug 30, 2024 · By the 1960s, scientists had amassed enough evidence to support the missing mechanism—namely, seafloor spreading—for Wegener’s hypothesis of continental drift to be accepted as the theory of plate tectonics. Ongoing GPS and earthquake data analyses continue to support this theory.

  7. 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. The theory of continental drift is most associated with the scientist Alfred Wegener.
