1 WEATHER AND WATER

2 EVAPORATION The process in which liquid water becomes water vapor

3 HUMIDITY The water vapor in the air

4 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

5 CONDENSATION The process in which water vapor becomes liquid water

6 CONDENSATION NUCLEUS A small particle on which water vapor condenses

7 CLOUD A visible accumulation of water on condensation nuclei, either as liquid or ice, usually high in the air

8 PRECIPITATION Any form of water that falls from the sky/clouds

9 RAIN Liquid form of precipitation. It stays liquid from beginning to end.

10 SLEET Precipitation that starts out as a liquid but freezes on the way down from the cloud to the Earth.

11 HAIL Precipitation in the form of balls of ice. Freezes in the clouds

12 FREEZING RAIN Liquid precipitation that freezes on contact once it has landed on surfaces on Earth (Cars, trees, grass, concrete)

25 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

26 PHOTOSYNTHESIS A process used by plants to convert water, carbon dioxide, and sunlight into carbohydrates and oxygen.

27 TRANSPIRATION The release of water from plants as a product of photosynthesis.

28 TEMPERATURE A measure of kinetic energy of the molecules of a material or substance.

29 THERMOMETER An instrument to measure temperature

30 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.

31 DEW Water that condenses on surfaces when the temperature drops below the dew point.

32 FROST Frozen dew. This occurs when the dew point is below 0 o C (32 o F)

33 WATER CYCLE PROJECT

34 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:

35 Evaporation Condensation Precipitation Condensation Nucleus Run Off Photosynthesis Transpiration At least an area of 500 miles Dew Dew Point Frost Temperature

58 What is weather?

59 WEATHER The state of the atmosphere at a given time A description of the weather includes observations and measurements of temperature, precipitation, air pressure and cloud cover. Weather changes from day to day and season to season

60 Is our weather normal for this time of year?

61

62 CLIMATE Weather conditions over a long time. Climate helps to describe a region Climates change, but over years or centuries not days

63 SEVERE WEATHER Weather that is dangerous or causes damage

64 Name some types of severe weather

65 SEVERE WEATHER Tornados Hurricanes/Cyclones Thunderstorms/floods Blizzards Dust storms

66 HURRICANES Form over oceans Water temperature of 27 degrees C (81 degrees F) Low pressure Cause damage due to wind and water

67 METEOROLOGY The study of Earths weather A person who studies weather is called a Meteorologist What do we call someone who studies the climate?

68 WEATHER TOOLS Thermometer Hygrometer Wind Vain or compass Anemometer Barometer Visibility Temperature Humidity Wind direction Wind speed Air pressure Fixed point in the distance

69 TEMPERATURE Average kinetic energy How hot/cold the air is

70 HUMIDITY The amount of water vapor in the air

71 WIND DIRECTION The direction the wind is coming from

72 WIND SPEED How fast the wind is blowing

73 AIR PRESSURE The force of air pushing in all directions

74 VISIBILITY The distance a person can see through the air.

75 OUR ATMOSPHERE Permanent Gases 78% Nitrogen 20% Oxygen And other gases Variable Gases 0 – 7% Water Vapor 0.01 – 0.1 % Carbon Dioxide And other gases

76 ATMOSPHERE Many Layers Troposphere: Closest layer Where weather occurs Stratosphere: 10-50 KM above Earth Ozone layer Jet Stream Airplanes fly here

77 ATMOSPHERE CONTINUED Thermosphere: Least understood Air is very thing Region of the atmosphere first heated by the Sun Up to 1500 degrees C or hotter Ionosphere: Large number of electrically charged ions

78 ATMOSPHERE PART 3 Exosphere: Atoms and molecules escape into space 300-600 KM above Earth

79 What causes the seasons?

80 What ways is heat transferred?

81 Conduction Convection Radiation

82 CONDUCTION Transfer of heat energy by touching

83 CONVECTION The transfer of energy/heat though a fluid, like air

84 RADIATION The transfer of heat/energy from a single source such as the Sun.

85 AIR MASS A large body of air with uniform temperature and humidity. Air masses have distinct boundaries and can extend hundreds or thousands of KM over Earths surface Can reach up into the Troposphere

86 3 TYPES OF AIR MASSES Tropical Warm air Polar Cold air Arctic Extremely cold air
