This term in we have been learning about the structure of the Earth and its layers. There are five layers of the Earth. The crust which in fact is over one hundred kilometres thick. The upper mantle which out of the five is the thickest of all the layers, which reaches a high temperature of over five hundred degrees celsius! Next we have the mantle which is a insanely hot layer of thick molten lava. After that then we are really starting to heat up in the outer core at thousands of degrees celsius. Finally we have the last layer of the Earth the inner core which reaches the surface of the Sun!!!
Tectonic Plates have three boundaries convergent,divergent and transform. The tectonic plates are like a ginormous jigsaw puzzle that will never ever will be able to be lifted. They sit on the lithosphere a minor layer in between the Crust and Upper Mantle. Our tectonic plates are made up of oxygen,silicon,aluminum,iron,calcium,,sodium,potassium and magnesium. Millions of years ago two hundred and fifty to be precise all the landmass on Earth was all one continent called Pangea. One hundred million year later caused by the tectonic plates broke up into two called Laurasia and Gondwanaland. Then we have the two Jurassic and Cretaceous Periods. Finally then we start to see the land masses we see today.
