I have learned alot about them one thing that i have learned is that when two plate are gonna collide the one that is less dense will go on the top and the one that is more dense will sink to the bottom becoming magma. The layers of the earth are the outter layer which is the crust but another name for it is (lithosphere)which are were plates and rocks are, and that is the thinest of them all. Following that is the Mantle and that is the thickest and there is were the magma is stored also known as were the convection currents happen. After that is the ineer core and that is were it is made out of liquid metal and they generate a magnetic field. Lastly is the Inner Core which is made of solid metal and is very dense. Now about Seismic Waves scientist study the way they bounce of of the inner and outter core and stuff like that they see what direction they go and how they reflect from it. They also there are two different types of waves called the "S" wave and the "P" wave.
