Answer :
Final answer:
Coal plants were largely responsible for the acidification of over 7000 lakes in Ontario, Canada due to the release of sulfur dioxide and nitrogen oxide gases. The gases combine with water vapor in the air to form sulfuric acid and nitric acid, which lowers the pH level of the lakes.
Explanation:
The acidification of over 7000 lakes in Ontario, Canada was largely due to coal plants. When coal is burned, it releases sulfur dioxide and nitrogen oxide gases into the atmosphere. These gases combine with water vapor in the air to form sulfuric acid and nitric acid, which can then be deposited in lakes through rainfall or snowfall. The acids lower the pH level of the lakes, making them more acidic.
