What Best Describes the Theory of Plate Tectonics
The theory of plate tectonics state that the pieces of Earths lithosphere are in slow constant motion. The plates act like a hard and rigid shell compared to Earths mantle. Plate Tectonics Ppt Download Sections of Earth s continents are in slow constant movement. . Plate tectonics is the modern version of continental drift. Sections of Earth that shift are part of Earth s asthenosphere. Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of continental drift Wegener proposed that the continents plowed through crust of ocean basins which would explain why the outlines of many coastlines like South America and Africa look like they fit together like a puzzle. They are also driven by molten material. Seafloor and continents move around on Earths surface but what is actually moving. These pieces are called tectonic plates and they come in various shapes and sizes. The plate...
