Question | Answer |
---|---|
Which of the following groups are renewable resources? | Water, plants and animals, sunlight, and wind. |
What would be the best place to construct a series of turbines to generate electrical energy? | Near an ocean coast where the wind blows consistently. |
What are some of the advantages of using solar energy? | Sunlight reaches the Earth’s surface quickly. |
Use of hydroelectric energy depends upon - | Availability and power of moving water. |
Alternative Energy Resource | Energy generated by natural processes that is renewable |
Wind Energy | Energy that comes from changing the power of moving air into a useful form |
Solar Energy | Energy that comes from the Sun |
Biofuel/Biomass | Fuel made from plants, animal wastes, and decomposing plant and animal tissue |
Geothermal | Energy that comes from the natural heat inside the Earth |
Hydroelectricity | Electricity made from the energy of moving or falling water |
Renewable resource | Materials from the Earth that can be replaced by nature within a relatively short period of time; example: trees |
Nonrenewable resource | Materials from the Earth that cannot be replaced within a reasonable amount of time; for example: oil, coal, and natural gas |
Fossil Fuel | A flammable material made from the waste and remains of plants and animals in the Earth's crust that is used to produce heat and power |
Pollution | Materials introduced into an environement that cause damage, discomfort, or instability |
Hot water is pumped up from deep inside the Earth and is used to heat homes or to generate electricity | Geothermal Energy |
As water flows through a dam, a generator is turned and creates enough electricity for thousands of homes | Hydroelectric |
Plants and manure are burned. The heat that is created is used to turn a generator. The generator creates electricity that will provide power to many homes | Biofuels |
