The class goes down into the depths of the Earth, what will they find?
Hello Class, today we will be exploring the center of the Earth.
This class is the outer core, its the layer between the Mantle and the Inner Core, The outer core is what creates the magnetic field around our planet. Come out Carlos!
Here we are in the crust, this is the thinnest layer and goes down very deep, the crust of the Earth is composed of a great variety of igneous, metamorphic, and sedimentary rocks. The tectonic plates are part of the crust, they are moved by the convection currents created by the mantle. Now onto the mantle.
This is the Mantle, it is not solid or liquid it is both. This is the largest layer and goes down to the core. The mantle is heated by the outer core through convection currents, which causes plate tectonics, we will talk about this later. We should get out of here quick, where is Carlos?!
This is the inner core this is the very center of the earth. The inner core is the very center of the Earth and the hottest part of the planet. It is mainly a solid ball with a radius of about 1,220 km Oh, there you are, Carlos!
Here I am!
That was very fun! Now class what have you learned?
