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 guess about how the continents got where they be today. He cerebration that they had started as one supercontinent named Pangaea, and whence d severinged to their current position. His theory wasnt believed during his condemnation because he had no mood to prove it. in that respect were roughly things that back his theory up like the analogous fossils beingness found on different continents with different climates and the way the edges of the continents operate together like a puzzle. Today, we know he was adjust in thinking that. The proof we have is because of the denudation of architectonic plates. They ar giant plates that carry the continents. They flow because they atomic number 18 on the asthenosphere, a plastic-like layer of the mantle. They move because of something called a convection current. In these currents in the asthenosphere, the cold plastic-like mantle is denser so it goes down impending to the a mount of money of the Earth and pushes the warmer mantle up. The squeeze and temperature there are higher in the lower area, so the once cooler mantle becomes hot, and the hot mantle becomes cool. They then switch, and keep switching, and thrust the plates. These plates are the cause of earthquakes, tsunamis, the creation of mountains, rift valleys, and volcanoes. Different things adventure at different types of boundaries.

On convergent boundaries, twain or more plates move towards each other and collide, causing earthquakes. This is also how tsunamis are caused. An earthquake at sea occurs, and sends a w ave of weewee that travels at great speeds,! and crashes when it gets to the shore. Also, when two plates collide, they may hit and go up and form mountains. On a divergent boundary, two or more plates move away from each other. On these boundaries, rift...
