What have you learned in class? Well in science class Iv'e learned about the different parts of earth. The crust,mantle,and the core. The crust is the outermost layer of earth. The mantle is the middle layer of earth. The mantle is made of molten rock which shoots out of volcanoes. The last layer of earth is called the core. The core is actually made of many metals(mostly magnetic to be exact).It is made of iron,nickle,alloy,and some other unidentified metals. That is why the earth has a magnetic pull. Like a magnet it has north and south poles. This is what I have learned in class.
