ESS205H1 Lecture 5: Lecture 5
Document Summary
If you add heat, it becomes gas and if you extract heat it becomes solid. Everytime you extract or add heat, there is an energy change. There are different water reservoirs on the earth (rivers, oceans, groundwater, atmosphere) Residence time is the average amount of time that water stays in a reservoir. Water constantly moves from one reservoir to another. There is a heat and matter exchange: the heating of the sunlight of the water in the equator warms it up so it rises, around equator, there is a region of very low pressure. This is important because lower pressure means higher temperature and higher greenhouse gases and water vapor in the air. Therefore, there is heavy precipitation: air moves from lower air pressure to higher air pressure in the poles and equator. Bigger heat transfer so air moves from lower to higher pressure. In the upwelling case, it"s not supposed to rise up but it happens.
