Weather and Water. Evaporation. The process in which liquid water becomes water vapor. Humidity . The water vapor in the air. Relative Humidity.
E N D
Evaporation • The process in which liquid water becomes water vapor
Humidity • The water vapor in the air
Relative Humidity • The amount of water vapor in the air compared to the amount of water vapor needed to saturate the air at a give temperature; expressed as a percentage
Condensation • The process in which water vapor becomes liquid water
Condensation nucleus • A small particle on which water vapor condenses
Cloud • A visible accumulation of water on condensation nuclei, either as liquid or ice, usually high in the air
Precipitation • Any form of water that falls from the sky/clouds
Rain • Liquid form of precipitation. It stays liquid from beginning to end.
Sleet • Precipitation that starts out as a liquid but freezes on the way down from the cloud to the Earth.
Hail • Precipitation in the form of balls of ice. Freezes in the clouds
Freezing Rain • Liquid precipitation that freezes on contact once it has landed on surfaces on Earth (Cars, trees, grass, concrete)

Run Off • When rain lands or snow melts and the water flows, it carries with it anything it touches.For example: • -Oil from shingles on the house -Fertilizers -Dirt/sand
Photosynthesis • A process used by plants to convert water, carbon dioxide, and sunlight into carbohydrates and oxygen.
Transpiration • The release of water from plants as a product of photosynthesis.
Temperature • A measure of kinetic energy of the molecules of a material or substance.
Thermometer • An instrument to measure temperature
Dew Point • The temperature at which a volume of air is saturated with water vapor; condensation occurs when the temperature drops below the dew point.
Dew • Water that condenses on surfaces when the temperature drops below the dew point.
Frost • Frozen dew. This occurs when the dew point is below 0oC (32oF)
Criteria • In any means you deem school appropriate, • i.e.: Song, Comic, Video, Rap, creative story, etc. NOT AN ESSAY!!! • tell the story of a drop of water as it goes through the water cycle. The story must start and end in a toilet. The story must include:
Evaporation • Condensation • Precipitation • Condensation Nucleus • Run Off • Photosynthesis • Transpiration • At least an area of 500 miles • Dew • Dew Point • Frost • Temperature

Question 5 • What falls from the sky as water and freezes before it reaches Earth? • Hail • Rain • Sleet • Freezing Rain
Question 6 • What happens when the temperature falls below the dew point? The air absorbs more water vapor and it condenses into clouds The air absorbs more water vapor and it condenses onto any surface The air releases water vapor and it condenses into clouds The air releases water vapor and it condenses onto any surface.
Question 7 Which statement is true? • The higher the temperature the less water vapor the air can hold before it is saturated • The lower the temperature the less water vapor the air can hold before it is saturated • Temperature does not affect how much water vapor the air can hold
Question 8 • What is relative humidity? The amount of water vapor needed to saturate the air half way The amount of water vapor in the air compared to how much is needed to saturate the air The amount of condensation on surfaces compared to the amount of water vapor in the air.
Question 9 • What is true about convection? Air rises from an area of extreme heating until it cools then falls back to Earth. Air rises from an area of extreme cooling until it heats up and then falls back to Earth Convection is a process that is not understood by scientists.
