The Water Cycle is always moving between the atmosphere and the surface of Earth. There is always the same amount of water on Earth. Precipitation- After condensation occurs (forming clouds), water droplets fall in various forms of precipitation rain, snow, freezing rain, sleet, or hail, depending – upon weather conditions. Evaporation/Transpiration-Water enters the atmosphere as water vapor (gas) through evaporation and transpiration, plants releasing water vapor. (Liquid to a gas) Condensation- happens in the atmosphere as water vapor (gas) changes to water Dew droplets (liquid).Clouds form because of condensation. forms when water vapor condenses directly onto a surface Run-off- If precipitation falls on land surfaces, it always attempts to move back toward sea level Weather conditions and patterns can be predicted WEATHER FORECASTING - based on weather data collected from various sources. meteorologists Basic weather conditions can be observed and/or measured by (a scientist that studies the weather) at national weather data collection sites. order to make weather predictions, the data should be collected on a regular In basis over a period of time.
