1 The Earth’s Interior Crust (Lithosphere) Mantle Outer Core Inner Core

2 The deepest part of the earth (1512 miles deep) is a solid that contains both iron and nickel. It is because of this that the center of the earth is a magnet, a compass. It generates a magnetic field that protects the earth from flying out of orbit.

3 Outer Core Outside of the inner core lays the outer core (1419 miles deep). This is much like the inner core with the exception that it is a liquid that contains sulphur and oxygen (which lowers the melting point).

4 Mantle Occupying 1789 miles of the earth is the magma (iron and magnesium) that makes up the mantle. Upper and lower It is extremely hot!! goopy; very plastic-like. (upper mantle) Mostly solid (lower mantle)

5 Crust Also called lithosphere This is the top layer of the earth, which is basically hardened mantle (magma). It contains two segments, the oceanic and continental crusts. Note: this is the same crust, it just depends how thick it is to determine if it is part of the Oceanic or Continental Crust.

6 Crust… cont’d For instance, if you drained all of the water from earth, then there would be one, giant Continental Crust. Likewise, if you flooded everything, you'd have one, giant Oceanic Crust.

7 Read About Earth’s interior Our Text p. 4-6

8 The Earth’s Interior – Layer Names Outer Core Lithosphere or crust Inner Core Mantle - Lower Mantle - Upper

9 The Earth’s Interior - Composition Liquid - magma Solid – hardened mantle Solid – iron & nickel Mostly Solid Goopy, plastic-like
