Question

predicting human impact on freshwater sources
page 1 page 2
acid rain is rain that contains acids. the acids in this type of rain eventually end up in lakes, rivers, and groundwater. acids decrease the ph of freshwater sources. changes in ph may affect the organisms that live in lakes and rivers and the quality of groundwater, a source of drinking water. sulfur oxides, including sulfur dioxide, are chemicals that contribute to the formation of acid rain. sulfur dioxide is released into the atmosphere when fossil fuels like coal, petroleum, and natural gas are burned to produce electricity.
what can people do to lessen the effect of energy production on the ph of freshwater sources? check all that apply.
stop producing electricity
produce energy using water power
use electricity or energy - saving products
create technology to capture sulfur dioxide
use petroleum instead of coal to produce electricity
increase the use of coal in the production of electricity

Explanation:

1. Water power is a renewable, non-fossil fuel energy source, so it does not release sulfur oxides that cause acid rain and lower freshwater pH.
2. Energy-saving products reduce overall energy demand, which decreases the burning of fossil fuels that emit sulfur oxides.
3. Capturing sulfur dioxide prevents this acid-rain-forming chemical from entering the atmosphere and lowering freshwater pH.

The other options are ineffective or harmful: stopping electricity production is impractical; petroleum still releases acid-rain-causing emissions; increasing coal use would raise sulfur oxide emissions and worsen pH reduction.

Answer:

• produce energy using water power
• use electricity or energy-saving products
• create technology to capture sulfur dioxide
