Figure 1.3 A chemically differentiated Earth. The core consists mostly of iron; the outer part is molten. The mantle, the largest zone, is made up primarily of ferromagnesian silicates (see chapter 2) and, at great depths, of oxides of iron, magnesium, and silicon. The crust (not drawn to scale, but exaggerated vertically in order to be visible at this scale) forms a thin skin around the earth. Oceanic crust, which forms the sea floor, has a composition somewhat like that of the mantle, but is richer in silicon. Continental crust is both thicker and less dense. It rises above the oceans and contains more light minerals rich in calcium, sodium, potassium, and aluminum. The "plates" of plate tectonics (the lithosphere) comprise the crust and uppermost mantle. (100 km = 60 miles) downward According to this Figure, the Earth can be divided up into layers by chemistry or by function. The biggest part of this diagram is showing the Earth divided up by nonsense, the Earth can't be divided up; it is just the Earth. function, like the lithosphere and asthenosphere. chemistry, like the crust and mantle.
