EVERYDAY SCIENCE

Detailed explanation-1: -Renewable resources include timber, wind, and solar while nonrenewable resources include coal and natural gas.

Detailed explanation-2: -Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us. Fossil fuels-coal, oil and gas-on the other hand, are non-renewable resources that take hundreds of millions of years to form.

Detailed explanation-3: -Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.

Detailed explanation-4: -Renewable resources include solar energy, wind, falling water, the heat of the earth (geothermal), plant materials (biomass), waves, ocean currents, temperature differences in the oceans and the energy of the tides.

Detailed explanation-5: -Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy.
