We can view the spectra of celestial objects to identify the elements and compounds that are present.

Spaceship Earth: The Materials

Manifest

Erath is divided into three main regions: the core, the mantle and the crust.

• The core is thought to consist largely of iron with some nickel.

The crust is the outer solid shell of earth often called the lithosphere.

The Lithosphere: Organic and

Inorganic

The lithosphere is compose of the following rocks:

• Silicate minerals• Carbonate minerals• Oxide minerals• Sulfide minerals

Thousands of mineral compounds make up the

inorganic portion of the solid crust and organic portion

makes up all living creatures.
