Which of the following gases is released from the structure labeled C in the diagram
Water vapor
Which of the following best describes a potential advantage of using geothermal energy instead of solar farms for power generation?
geothermal energy can be harnessed without destroying large tracts of habitat, whereas solar farms require large amounts of space.
Which of the following is required to convert geothermal energy into electricity
groundwater
Which of the following best describes a potential negative environmental effect of fossil fuel extraction?

Purity is a major factor in determining the type of coal used for energy. Which of the following types of coal are correctly paired with a description of its purity and common use?
Anthracite is considered the highest grade coal because it is almost pure carbon and it is often used for domestic heating.
Natural gas, a nonrenewable fossil fuel, is often seen as an alternative fuel in the worldwise transition to a renewable energy future. Which of the following statements best explains why natural gas is often used as a fuel when countries are transitioning from non renewable to renewable energy sources?
Natural gas burns more efficiently and cleanly than other sources of carbon based fossil fuels, thus contributing to a reduction in atmospheric carbon dioxide.
