Geologists 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

Climate patterns

Gas emissions

Ph levels

Human activity

The geologists would most likely track pH levels in the surface waters. Acid rain, caused by the interaction of sulfur dioxide and nitrogen oxides with the atmosphere, can decrease the pH of surface waters, making them more acidic. This increased acidity can have detrimental effects on aquatic ecosystems, such as harming fish, algae, and other aquatic organisms. By monitoring the pH levels in surface waters, geologists can assess the impact of acid rain on these ecosystems.
