Water in the atmosphere Water is always moving between the surface of earth and the atmosphere this is water cycle Cycle it is any series of events that repeat in the same order over and over again Plants make transpiration and animal respiration The two process form water vapor in atmosphere Condensation For condensation to occur tiny particles must be present in the atmosphere Most of these particles are salt crystals, dust, bacteria or smoke Temperature is also a major factor in condensation Warm air hold more water vapor than cold air Liquid water that condenses from the air onto a cooler surface is called dew the temperature at which condensation begins is called Dew point Humidity is a measure of the amount of water vapor in the air relative Humidity It is the percent of water vapor in the air compared to the maximum amount Of water vapor the air can hold at particular temperature Relative Humidity can measuring by using psychrometer Or digital hygrometer  Water leaves the atmosphere When form cloud and condensation continue the droplets may grow heavy and fall down Precipitation it is any form of water that form from a cloud and reaches the earth surface Types pf precipitation Rain most common kind of precipitation Comes in various forms depending on the size of the water droplets Measuring precipitation If a town receive a large snowfall need to track how much snowfall to determine how safe its to travel Rain can be measured by using a rain gauge
