Biosphere - ANSWERSThe totality of life on Earth; the parts of the solid Earth,
hydrosphere, and atmosphere in which living organisms can be found
Closed systems - ANSWERSA system that is self-contained w/ regard to matter. That
is, no matter enters or leaves
Earth science - ANSWERSThe name for all the sciences that collectively seek to
understand Earth. It includes geology, oceanography, meteorology, and astronomy
Earth system science - ANSWERSAn interdisciplinary study that seeks to examine
Earth as a system composed of numerous interacting parts or subsystems
Environment - ANSWERSEverything that surrounds and influences an organism
Geology - ANSWERSThe science that examines Earth, its form and composition, and
the changes it has undergone and is undergoing
Geosphere - ANSWERSThe solid Earth, the largest of Earth's four major spheres
