The Water Cycle • Clouds and Water Vapor
What’s Up With Water? • Water is everywhere. • Water can be found in 3 different states, solid, liquid, and gas. • Water falling from the sky is called Precipitation. • There are four types of precipitation: rain, snow, sleet, and hail.
Types of Precipitation • Precipitation is determined by air temperature • Rain- in warm air, water vapor forms rain • Snow- cold air causes water vapor to form snowflakes • Sleet- small ice pellets • Hail- lumps of ice
What is a Cloud? • Clouds are formed by warm air being forced upward. ( moist air is lighter than dry air) • Warm air expands then cools • Water vapor condenses into water droplets • Droplets are so small they remain suspended in air and form around dust particles and other particles in the air. • Billions of these droplets form a cloud
Types of Clouds • Clouds are classified by shape and height • Shape and height vary because of temperature, pressure, and amt. of water vapor • Three main types- Cirrus, Stratus, and Cumulus • Three main heights- Cirro (high), Alto (middle), Strato (low)
