WebbPlate-Tectonics Theory. According to the now generally accepted "plate-tectonics" theory, scientists believe that the Earth's surface is broken into a number of shifting slabs or plates, which average about 50 miles in … Webb20 maj 2024 · 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. He is shown here in Greenland. We don’t perceive that the continents we live on are moving.

WebbThe theory of plate tectonics. Is the theory that the earths lithosphere is divided into tectonic plates that move around on top of the asthenosphere. Layers of the earth: *Lithosphere. -the outer most, rigid layer of the earth. -composed of the crust and the rigid upper part of the mantle. -divided into pieces called tectonic plates. WebbTo explain how this change happened, scientists developed the theory of plate tectonics. Plate Tectonics Scientists have studied the theory of plate tectonics for many years. This theory states that the Earth's crust is made of several plates, each moving independently of the others. Studies by NASA and radio astronomy sites around the world ...
