Geosphere
All living organisms on Earth and their environments.
Biosphere
All the water on Earth, including oceans, rivers, lakes, and groundwater.
Hydrosphere
The layer of gases surrounding the Earth.
Atmosphere
Science that studies the different Earth subsystems.
Earth Systems Science
The outermost layer of the Earth, composed of rock and soil.
Crust
The physical location where an organism lives.
Habitat
The process by which water vapor changes into liquid water.
Condensation
The most abundant gas in the atmosphere.
Nitrogen
The system where all living organisms belong.
Biosphere
The process of breaking down rocks into smaller pieces.
Weathering
The role of an organism in its ecosystem.
The movement of water from the Earth's surface into the atmosphere and back.

An underground layer of rock or soil that holds water.
Aquifer
The highest layer of the atmosphere.
Exosphere
System involved in the formation of a natural climate.
The process by which molten rock from the Earth's interior reaches the surface.
Volcanism
The process by which the cell converts glucose into usable energy in the form of adenosine triphosphate (ATP).
