The Lithosphere The Lithosphere is the upper surface of the earth composed of the SOLID upper mantle which is made up of the earth’s crust including both Oceanic Crust and Continental Crust. Press to continue

The Lithosphere The various Continental Plates link together to make up the Lithosphere. Press to continue

The Earth’s Mantle The earth’s mantle actually exists in two distinct layers. The upper Mantle is composed of rock with the consistency of plastic (like silly putty) called The Asthenosphere The lower layer of the Mantle is rigid and solid. Press to continue

The Earth’s Mantle The Asthenosphere The continental plates drift over the soft asthenosphere as the heat of the earth’s core rises creating currents that Result in Continental Drift. Press to continue

The Outer Core The Outer Core of the Earth consists of liquid rock composed of Iron with 12% sulphur silicon, oxygen, nickel and potassium Press to continue

The Inner Core The Inner Core of the Earth consists of SOLID rock composed of Iron with 10-20% nickel. Some physicists believe that the movement of electrical charges between the inner and outer core produce the earth’s magnetic field. Press to continue

How do we KNOW these levels exist? Seismologists study Earthquakes. Earthquakes produce shock waves that travel through the earth and can be measured on the other side of the earth. P waves (primary waves) go through solid and liquid. The vibrate differently passing through solids than when they pass in liquid. S waves (secondary waves) only go through solids. Press to continue
