What Is Crust?

The crust is the top layer of the earth where we are standing right now. It includes both the lands surface and the ocean bed. The crust of the earth sits on top of the lower layer called the mantle, which is molten rock (lava). The crust floats around on top of this mantle, hence the movement of the continents and oceans.
