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