1. Renewability (Determined by replacement rate and quantity)

1.1. Renewable Resources

1.1.1. Definition

1.1.1.1. A renewable resource is a resource which is replaced naturally and can be used again

1.1.2. Examples

1.1.2.1. Oxygen, fresh water, solar energy, wind energy, timber, and biomass. Renewable resources may also include goods commodities such as wood, paper and leather.

1.1.3. Infinite (Unlimited)

1.2. Non-Renewable Resources

1.2.1. Definition

1.2.1.1. A resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption.

1.2.2. Example

1.2.2.1. Most fossil fuels, such as oil, natural gas and coal are considered nonrenewable resources in that their use is not sustainable because their formation takes billions of years.

1.2.3. Finite (Limited)

1.3. Is replacement/replenishment rate quick enough to suffice for depletion rate? Time of formation rate?

2. Biosphere

2.1. Sun (Solar Energy)

2.2. Ecosphere

2.2.1. Atmosphere

2.2.1.1. Air (Wind Energy)

2.2.2. Hydrosphere

2.2.2.1. Water (Wave Energy)

2.2.3. Lithosphere

2.2.3.1. Coal, fossil fuels

3. Definition

3.1. Anything that people can use which comes from nature. Gathered from the earth. Naturally occurring. Wide known usage and application, widely used. Has economic value.
