<u>Explanation</u>: The source for the water flow observed is an artesian aquifer. This type of aquifer contains groundwater under positive pressure. In order to reach hydrostatic equilibrium, a spring will form through a crack/weak spot in the bedrock. For this type of geological formation, water will exit at a level lower than that of the water table.
The answer is the second one. Deforestation of rain and forests and other parts of the world volcanic eruptions and widespread forest fires. This activity has contributed greatest amount of carbon dioxide into the atmosphere over the past 100 years.
