1 Natural ResourcesSomething found in nature that can be used to benefit us.Examples:Air, water, soilBiological resources (plants and animals)Raw materials (minerals)Space and landWind, geothermal, tidal and solar energyAre often classified into renewable or nonrenewable resources.
2 Nonrenewable Resources A natural resource that exist in a fixed amount.They are renewed very slowly or not at all.Consumption is faster than the rate it can be replaced.
3 Nonrenewable Resources CoalOilNatural GasPetroleumNuclear Energy
4 Nuclear fission uses uranium to create energy. Nuclear EnergyNuclear fission uses uranium to create energy.Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!
5 Coal, Petroleum and Natural 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.
6 HMMMM....If nonrenewable resources are resources that cannot be re-made at a scale comparable to its consumption, what are renewable resources?
7 Renewable ResourcesNatural resources that can be replaced by nature at a rate close to the rate at which they are used.● Solar ● Geothermal● Wind ● Biomass● Water
8 Explain why energy from the sun is renewable SOLAREnergy from the sun.Explain why energy from the sun is renewable
9 GEOTHERMAL Energy from Earth’s heat. Explain why energy from the Earth’s heat is renewable.
