Plate Tectonics

Plate Tectonics. The theory that says the earth’s outer shell is not one solid piece, but instead is comprised of many moving plates. Continental Drift Theory. the world was once made up of a single super-continent, pangaea, that separated and drifted apart, forming the seven continents .

The Theory of Plate Tectonics

The Theory of Plate Tectonics. Plate Tectonics. Plate tectonics is the theory that explains why and how continents move. By the 1960s evidence supported continental drift which led to the development of plate tectonics. How Continents Move.

Theory of Plate Tectonics

Chapter 3 Lesson 3. Theory of Plate Tectonics. What Is The Theory of Plate Tectonics?. Key Answer: The theory of plate tectonics states that Earth’s plates are in slow motion driven by convection currents in the mantle. Explains the formation, movement, & subduction of Earth’s plates

Waves and Plate tectonics

Waves and Plate tectonics. Plate tectonics. How did the theory come about? The German meteorologist Alfred Wegener advocated "continental drift" in 1924. But people didn’t believe this idea. People started to think differently in the 1960’s due to evidence such as ;
