Example Questions
Example Question #51 : Understanding Eco Chemical Cycles
Which of the following best describes the cause of acid precipitation?
None of these
Addition of hydrochloric acid to reserves of water
Sulfur dioxide and nitrogen oxide reacting with water in the atmosphere
Sulfur dioxide and nitrogen oxide reacting with water in the atmosphere
Sulfur dioxide and nitrogen oxide reacting with water in the atmosphere
Acid precipitation is a type of precipitation that is acidic, meaning that it has a pH of less that 7. Acid precipitation is caused by the reaction of sulfur dioxide and nitrogen oxide with water in the atmosphere, which produces acids. The production of sulfur dioxide and nitrogen oxide is directly linked with human industrialization.
Example Question #52 : Understanding Eco Chemical Cycles
Which of the following is not a carbon reservoir?
Peat bogs
Glaciers
Atmospheric
Forests
Coal
Glaciers
Atmospheric , fossil fuels (including coal), peat, and organic material in a durable form (such as the cellulose of trees) are the reservoirs of the carbon cycle. Glaciers, on the other hand, are primarily water and are one of the reservoirs of the hydrologic (water) cycle.
