A biome is a community of plants and animals that have common characteristics for the environment they exist in.
The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic datum § Vertical datum).
A plant community (sometimes "phytocoenosis" or "phytocenosis") is a collection or association of plant species within a designated geographical unit, which forms a relatively uniform patch, distinguishable from neighboring patches of different vegetation types.
In meteorology, precipitation is any product of the condensation of atmospheric water vapor that falls under gravity.
Soil is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life.
Vegetation is an assemblage of plant species and the ground cover they provide.
