GEOLOGY

Detailed explanation-1: -He called this movement continental drift. Pangaea Wegener was convinced that all of Earth’s continents were once part of an enormous, single landmass called Pangaea. Wegener, trained as an astronomer, used biology, botany, and geology describe Pangaea and continental drift.

Detailed explanation-2: -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 Today, the theory of continental drift has been replaced by the science of plate tectonics.

Detailed explanation-3: -Continental drift is the hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations.

Detailed explanation-4: -Wegener’s continental drift theory introduced the idea of moving continents to geoscience. He proposed that Earth (opens in new tab) must have once been a single supercontinent before breaking up to form several different continents.

Detailed explanation-5: -Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift.
