Which of the following best describes the use of a renewable resource? Question 1 options: Natural gas is extracted from deep in the Earth and piped to customers to use for cooking. Water falls through openings in a dam turning turbine blades that generate electricity. We use gasoline to power our cars to get to work and school each day. Most power plants burn fossil fuels to generate electricity for use in homes and offices. Question 2 (2 points) (03.05 LC) Which of the following best describes the use of a non-renewable resource? Question 2 options: Wind turbines gather energy from the wind and convert it into electrical energy. Water falls through openings in a dam turning turbine blades that generate electricity. The electronic signs along the highway are run by solar power. Nuclear energy heats water into steam that turns the turbines of a power plant. Question 3 (2 points) (03.05 LC) Which statement is true? Question 3 options: Solar energy is a non-renewable resource that is used by many countries all over the world. The combustion of biomass can replace fossil fuels in conventional power plants. Oil is a non-renewable resource that is hardly ever used, so there is not a concern of depleting the Earth's supply. Hydroelectric energy uses the energy from the sun, which is a renewable resource. Question 4 (2 points) (03.05 LC) Which statement is true? Question 4 options: Oil, a renewable resource, is processed to make jet fuel. Hydroelectric power is generated from moving water. Geothermal energy can be converted to electricity in solar cells. Propane, a renewable resource, is used in some heating systems. Question 5 (2 points) (03.05 LC) Which statement best describes the long-term effects of using renewable resources? Question 5 options: As populations decrease, renewable resources will also decrease. Melting glacier ice will supple more fresh water. As demand for renewable energy increase, fossil fuel use will decrease. There is an unlimited supply of fresh water on the Earth.
