  •  
  • Clouds are created from warm air forced upward, expands and cools. As the air cools the amount of humidity increases. When the humidity reaches 100 percent the air is saturated. The water soon condenses and makes little water droplets. The droplets fall from the sky called Rain.
  • Clouds are classified by height or shape. They also have different distances from earth’s surface. The shape and height of clouds vary with temperature, pressure, water vapor, and atmosphere
  • Clouds associated with Rain or Snow have the word Nimbus attached to them. Cumulonimbus: When a cloud turns into a Thunderstorm
  • Nimbus: Dark Rain Clouds(Latin) Little Sunlight can pass through them Clouds are 18Km Nimbostratus layered Bring Rain or Snow
  • Precipitation is water falling from clouds Cloud droplets form around small particles such as salt and dust Size depends on -strength of updrafts -rate of evaporation -air temp (rain, snow, sleet, hail)
  • Hail is precipitation in the form of lumps of ice. Hail is formed when nimbus clouds thunder water freezes to form Hail. Most Hail stones are smaller than 2.5cm but can grow as large as softballs.
