Natural Resources

2. Resources are limited and are either Renewable or Non renewable

What are Nonrenewable Resources?

• A resource that is formed at a rate that is much slower than the rate at which it is being used .

NUCLEAR ENERGYNuclear fission

uses uranium to create energy.

Nuclear energy is a nonrenewable

resource because once the uranium

is used, it is gone!

• Do not confuse fission with fusion. In fission, atoms split apart. In fusion, they join together

Fusion occurs in the Sun, and makes almost no waste. We have not achieved fusion here on Earth.

COAL, PETROLEUM, AND GAS

Coal, petroleum, and natural gas are considered nonrenewable

because they can not be replenished in a short period

of time. These are called fossil fuels.

HOW IS COAL MADE ???

Coal is mined from the ground

Oil and gas are then trapped underground

The are under pressure and

must be drilled

Fossil fuels are burned to produce

electricity

HMMMM....

If nonrenewable resources are resources that

cannot be re-made at a scale

comparable to its consumption, what

are renewable resources?

Renewable Resources

• A resource that is formed at a rate that is quicker than it is being used.

WATER or HYDROELECTRIC

Energy from the flow of

water.

Why is energy of flowing

water renewable?

WIND Energy from the wind.

GEOTHERMAL

Why is energy from the heat of the Earth

renewable?

BIOMASSEnergy from

burning organic or
