ANSWER:
Burning of fossil fuels has contributed most to the 'acidification of lakes' in Adirondack region.
Step-by-step explanation:
- When 'fossil fuels are burnt', they release air pollutants that contain nitrogen and sulphur.
- These elements form nitrogen dioxide and sulphur dioxide when they are released into the air.
- Further, these gases react with water to form acids. This acid then falls along with precipitation when it rains and that is why rain is called acid rain.
- This acid rain results in the deposition of acids on the surface of water bodies as well as other landforms on the earth.
