The geosphere includes the rocks and minerals on Earth â from the molten rock and heavy metals in the deep interior of the planet to the sand on beaches and peaks of mountains. The geosphere also includes the abiotic (non-living) parts of soils, and the skeletons of animals that may become fossilized over geologic time.
Four types of vaccines are currently available: 1  Live virus vaccines use the weakened (attenuated) form of the virus. 2  Killed (inactivated) vaccines are made from a protein or other small pieces taken from a virus or bacteria.
