Geologist working for the environmental Protection Agency monitor surface waters at sites across the country to determine the effects of acid rain on aquatic ecosystems. What type of information would the geologists most likely track?
Possible answers:
Gas emissions
Human activity
pH Levels
Climate patterns
The geologists would most likely track pH levels. Acid rain is known to have a lower pH due to the presence of pollutants like sulfur dioxide and nitrogen oxides. By monitoring pH levels in surface waters, the geologists can determine the extent of acidification and evaluate its effects on aquatic ecosystems. Gas emissions, human activity, and climate patterns may also be monitored to understand the sources and patterns of acid rain, but pH levels would be the most direct indicator of the effects of acid rain on aquatic ecosystems.
