Definitions:

Biogeochemical Cycles

Processes that recycle essential elements and compounds between the biological (living) and geochemical (non-living) components of the Earth.

Stable Ecosystems

Ecosystems that remain relatively constant in terms of their species composition, structure, and function despite disturbances.

Greenhouse Effect

The trapping of the sun's warmth in the planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.

Ozone Layer

A stratospheric layer of ozone molecules that absorbs and reduces the amount of ultraviolet radiation reaching the Earth's surface.
