Question

using vocabulary
for each pair of terms, explain the difference in their meanings.

1. natural resource/energy resource
2. acid precipitation/smog
3. biomass/gasohol
4. hydroelectric energy/geothermal energy

Explanation:

1. A natural resource is any substance or material that occurs in nature and has some value, such as minerals, water, and air. An energy resource is a natural resource that can be used to produce energy, like coal, oil, and wind.
2. Acid precipitation is rain, snow, or fog that contains high levels of acids formed from pollutants in the air. Smog is a type of air - pollution that is a mixture of smoke and fog, often containing harmful pollutants like ozone and particulate matter.
3. Biomass is organic matter, such as plants and wood, that can be used as a fuel source. Gasohol is a mixture of gasoline and ethanol (which can be produced from biomass), used as a fuel for vehicles.
4. Hydroelectric energy is produced by the force of flowing or falling water, typically from dams. Geothermal energy is heat energy that comes from the Earth's interior, used for heating, electricity generation, etc.

Answer:

1. Natural resource is a general nature - occurring material, energy resource is for energy production.
2. Acid precipitation is acidic weather, smog is a type of air - pollution mixture.
3. Biomass is organic fuel material, gasohol is a fuel mixture with biomass - derived ethanol.
4. Hydroelectric from water flow, geothermal from Earth's internal heat.
