PLATE TECTONICS!

    I am going to blog about plate tectonics today.This blog post will include the following: how the earth was formed,what Pangaea is,what are tectonic plates and what are six  plates.
    First things first the earth was once called Pangaea.Pangaea was made up as one continent.The continents were combined.Over time Pangaea started to break apart.North America was the first continent to break.Then came South America,Eurasia,India, and Africa.The reason they broke apart was because volcanoes.This happens because the plates move around in the earths crust and go down to the mantle.They have dead krill and other stuff from the seafloor on them.When they go to the mantle the heat burns them and produces carbon dioxide.When a volcanoe erupts the carbon dioxide is realeased.The seven main plates are the eurassian plate,indian plate,north american plate,south american plate,pacific plate,oceanic
