Which statements accurately compare the environmental impact of acquiring natural gas and oil? what are the two correct answers.
1. Both involve drilling deep into the earth.
2. Both can be surface mined.
3. Both can impact groundwater supply.
4. Neither produces wastewater when processed.
5. Neither produces atmospheric contaminants when processed.
1. Both involve drilling deep into the earth.
3. Both can impact groundwater supply.
The correct statements that accurately compare the environmental impact of acquiring natural gas and oil are:
1. Both involve drilling deep into the earth.
3. Both can impact groundwater supply.
To determine the two correct answers that accurately compare the environmental impact of acquiring natural gas and oil, we need to analyze each statement.
1. Both involve drilling deep into the earth: This statement is true. Both natural gas and oil extraction involve drilling deep into the earth to reach the respective reserves.
2. Both can be surface mined: This statement is not accurate. Oil can be extracted through surface mining using techniques like open-pit mining, but natural gas is not typically surface mined. Natural gas is usually obtained through drilling techniques like hydraulic fracturing (fracking) or underground mining called coalbed methane extraction.
3. Both can impact groundwater supply: This statement is true. Both natural gas and oil extraction can potentially impact groundwater supply. Drilling and extraction processes may pose a risk of contaminating groundwater sources with chemicals or by damaging underground water reservoirs.
4. Neither produces wastewater when processed: This statement is not correct. Both natural gas and oil processing can produce wastewater. During extraction and production, large volumes of water are often used, which can become contaminated and require treatment or proper disposal.
5. Neither produces atmospheric contaminants when processed: This statement is not accurate. Both natural gas and oil processing can release atmospheric contaminants. Combustion of natural gas and oil for energy production releases greenhouse gases (such as carbon dioxide) and other air pollutants that contribute to air pollution and climate change.
Therefore, the two statements that accurately compare the environmental impact of acquiring natural gas and oil are:
1. Both involve drilling deep into the earth.
3. Both can impact groundwater supply.
