Activity c

While working on activity c it became clear that dew point is a big part of the water cycle. Dew point is the amount of water vapor in the air, and at times this dew condenses into clouds that then produce precipitation after becoming dense enough. Areas with the most atmospheric moisture include places like Mexico and its warm waters (the Gulf of Mexico has a high surface temperature). When rising air begins to cool it can become saturated. very humid air requires little cooling to become saturated which increases the chance of precipitation. It is evident that greenhouse gas emissions can alter the way dew point effects weather patturnes and average temperatures. At a certain level i belive this can have an effect on a global scale.
