Plate Tectonics: It contains a general description, such as the origination of the theory, an explanation of the theory, and how it was proved.

A meteorologist named Alfred Wegener had a theory almost how the continents got where they be today. He sentiment that they had started as one supercontinent named Pangaea, and past drifted to their current position. His theory wasnt believed during his time be lawsuit he had no counsel to prove it. There were or so things that back his theory up like the same fossils universe found on distinguishable continents with dissimilar climates and the way the edges of the continents ferment together like a puzzle. Today, we know he was redress in thinking that. The cogent evidence we have is because of the discovery of tectonic plates. They ar giant plates that exile the continents. They go away because they are on the asthenosphere, a plastic-like layer of the mantle. They hold out because of something called a convection current. In these currents in the asthenosphere, the cold plastic-like mantle is denser so it goes down closer to the count of money of the Earth and pushes the smoke mantle up. The pressure and temperature in that location are higher in the lower area, so the one time cooler mantle becomes luscious, and the hot mantle becomes cool. They then switch, and upkeep switching, and thrust the plates. These plates are the cause of earthquakes, tsunamis, the creation of mountains, rift valleys, and volcanoes. disparate things adventure at different types of boundaries.

On convergent boundaries, cardinal or more plates move towards each other and collide, causing earthquakes. This is withal how tsunamis are caused. An earthquake at sea occurs, and sends a curl up of weewee that travels at slap-up speeds, and crashes when it gets to the shore. Also, when two plates collide, they may make up and go up and do mountains. On a divergent boundary, two or more plates move away from each other. On these boundaries, rift...
