The Cycle of Water on Earth :
The Cycle of Water on Earth Water cycle – continual movement of water from one place to another and from one state of matter to another

Surface Water Moves into Earth’s Atmosphere :
Surface Water Moves into Earth’s Atmosphere Evaporation – liquid water changes to water vapor
The sun is the driving force in the water cycle
Humidity – measure of amount of water vapor in the air
The more water vapor in the air, the more humid the air is
Why might places like Miami, Florida have more humidity than places like desert areas like Las Vegas, Nevada?
Water Moves from the Air to Earth’s Surface :
Water Moves from the Air to Earth’s Surface Condensation – process of gas changing to a liquid
Clouds
Fog
Water condenses close to the ground
Advection fog – moist air passes over a cool surface by advection (wind) and is cooled
Radiation fog - cooling of land after sunset by thermal radiation in calm conditions with clear sky.
Evaporation fog - created by cold air passing over warmer water or moist land
Slide 6:
Precipitation – larger droplets of water that fall to Earth’s surface in form of rain, snow, sleet, or hail
Runoff – water that flows across the surface of the ground
The Day in the Life of a Water Droplet :
The Day in the Life of a Water Droplet Pretend you are a drop of water. Describe your water cycle journey.
Should be 4 paragraphs
One paragraph for each stage of water cycle
Evaporation
Condensation
Precipitation
runoff
Slide 8:
Relative humidity – amount of water vapor in the air to the amount of water it could hold at its present temperature
Dew point – temperature at which condensation occurs
