Geologist working for the environmental protection agency monitors surface water at sites across the country to determine the effects of acid rain on aquatic ecosystems. What type of information would a geologist most likely track

Climate patterns

Gas emissions

pH levels

Human activity

The geologist in this scenario would most likely track pH levels in the surface water to determine the effects of acid rain on aquatic ecosystems. Tracking pH levels would provide valuable information on the acidity of the water and how it may be impacting the health of aquatic plants and animals. They may also track gas emissions, such as sulfur dioxide and nitrogen oxide, which are precursors to acid rain. Additionally, they may monitor climate patterns and human activity in the area to better understand the sources and impacts of acid rain.
