GEOLOGY

Detailed explanation-1: -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.

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 Today, the theory of continental drift has been replaced by the science of plate tectonics. The theory of continental drift is most associated with the scientist Alfred Wegener.

Detailed explanation-3: -Answer and Explanation: Wegener’s idea of continental drift was not accepted by the scientific community because he was unable to explain how the continents moved. He was only able to show that at one point, the continents were all connected into one large landmass.
