A natural resource that is used up once it is extracted fro example coal or metallic minerals.
A resource that is replaced by natural by natural processes at a rate that is faster than its usage.
Material present in the natural enviornment and recognized by humans as of practical worth minerals, siols, water, building stones and timber
Dry or wet acidic deposition of acidic material from the atmosphere, often resluting from sulfur and mitrate gases and particles emitted into the air from coal combustion in power plants.

The natural process of heating Earth's atmoshphere. Solar rays short wavelengths reach Earth's surface and are absorbed by and heats the lower atmosphere, which contains water vapor and carbon gases. When humans add 2 the carbon gases, they enhave this process raising tempeatures abour "natural levels"
The long erm atmospheric conditions of a place.

The environments of living organisms where weather, mineral nutrients and solar energy combine.
Where atmosphere ocean environments interact with solid earth environments to produce relief features such as river or glacial valleys and coastal cliffs and beaches.
