Document Summary
Precipitation can be snow, rain, hail, and sleet. At the surface, precipitation can become: surface water runoff (if infiltration rate is low), surface water storage, glacial ice, water for plants, groundwater or evaporated. Oceans account for 90% of total evaporation. Ninety percent of water evaporated from the ocean falls back on ocean as rain and the remaining 10% is carried by prevailing winds over continents. Evaporation is highest near the equator as direct sunlight produces the greatest heat budgets. Air at the equator rises, cools, and falls as rain, forming rainforests at the equator. Cooler, drier air descends along tropics of cancer and capricorn. At the other end of the scale, some parts of sub-himalayan india have. In some parts of the chilean desert, no rain has fallen in recorded history. received up to 22 m of rainfall in a single year. Living near the ocean doesn"t mean access to lots of precipitation.
