Natural resources

Types of natural resources:Renewable resources.Non-renewable resources.

The first kind of resources

RENEWABLE RESOURCES

Renewable resources are natural resources that can be replenished in a short period of time.

Examples of Renewable Resources

Oxygen.Wood.Water.

oxygen As we all know human being

and animals use oxygen for breathing , and plants

release oxygen, hence according to definition of renewable resources oxygen is being replenished so it is a renewable resource.

wood Wood grows naturally and is

renewable. we use wood for various purposes and it can grow

again for re-use and hence it is kind of a renewable resource.

Example: timber.

water Water continually moves

throughout the planet, with each climate receiving its own

kind and volume of precipitation. If a community overuses water, the source can temporarily run out, but it will come back eventually, followed by the definition it is a renewable resource.

The other kind of

resources

Non-Renewable ResourcesA non renewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

Examples of Non-Renewable Resources

Coal.Petroleum.Natural gas.

Coal coal is used as a fuel, it takes

millions of years to regenerate it, so once we dig it all up, and, burn it, then it's finished. it

doesn't renew itself every day. if somehow, a community uses, coal at a large scale comparable to its consumption. it will run out, and will have to wait for a long time, so that it will regenerate for use, which is practically impossible, so it is considered as non-renewable resource.

petroleum This type of resources are

resources for which there is a limited supply. So, The

supply of petroleum comes from the Earth itself and, as it typically takes millions of years to develop and is finite. 

Natural Gas Natural gas is the result of

decomposing plants and animals that were trapped beneath rock millions of years ago. So once its used it takes a millions of time to regenerate, so it is a non-renewable resource.

For example: Liquefied Petroleum Gas(LPG).

Misconceptions Many people have the

misconception that a resource's status of renewability means that it is an endless source. A renewable resource is not endless; rather, the Energy Information Administration (EIA) defines a renewable resources as "Fuels that can be easily made or 'renewed'."
