The Earth's Structure

My name is Kim Allen and I'm a second grade teacher at Augusta Prepratory Day School and this web page lesson helps teach my second graders the layers of the earth.

The structure of the earth is made up of three layers.  The crust, mantle, and core (inner core  and outer core).  The crust is the Earth's cool outer layer of mostly solid rock, the mantle is the Earth's vast middle layer, and the core is the Earth's super-hot center-the outer core is liquid and the inner core is solid.
