GEOLOGY

Detailed explanation-1: -In fact, plate tectonics actually combine two other theories, continental drift and seafloor spreading into a comprehensive global theory. It’s curious that the continents on opposite sides of the Atlantic Ocean fit together so well, almost like a jigsaw puzzle.

Detailed explanation-2: -Seafloor spreading disproves an early part of the theory of continental drift. Supporters of continental drift originally theorized that the continents moved (drifted) through unmoving oceans. Seafloor spreading proves that the ocean itself is a site of tectonic activity.

Detailed explanation-3: -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-4: -Note:Plate tectonics refers to the theory which deals with the dynamics of the Earth’s outer shell which is the lithosphere. Seafloor spreading refers to the geological process in which the tectonic plates of the earth split apart from each other.

Detailed explanation-5: -The theory of continental drift suggests that all the land masses on earth were once part of one supercontinent. Plate tectonics is the ability to measure the movement of land masses.
