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: -Based on the fit of the coastlines, fossil evidence, rock types, and mountain ranges found on separate continents, Alfred Wegener developed a new theory he called ‘continental drift’.

Detailed explanation-3: -The continents are embedded in the plates and drift passively with them, which over millions of years results in significant changes in Earth’s geography. The theory of plate tectonics is based on a broad synthesis of geologic and geophysical data.

Detailed explanation-4: -Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes.

Detailed explanation-5: -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.
