The number of times heads comes up when you toss a coin, number of students present in class, number of times a person has attended therapy sessions-these are all discrete variables. To help see the difference between continuous and discrete variables, imagine a really tall mountain with a trail leading up to the top.
Climate changes resulting from greenhouse gas increases could also significantly affect water supply and demand. For example, a local increase in temperature of several degrees Celsius could decrease runoff in the Colorado River Basin by tens of percent (25, 48).
  A: The greenhouse effect is the cause of global warming. Global warming, in theory, is one of the outcomes of the Greenhouse Effect. Well, the relationship between global warming and the greenhouse effect is that the greenhouse effect is part of the cause or you could say that it is a contributor to global warming.The greenhouse effect is when radiation from the sun gets trapped in Earth's atmosphere.lobal warming, in theory, is one of the outcomes of the Greenhouse Effect.
