  1. Weather Unit Foldable • In the upper right hand corner write Your name Today's date Core

  2. What is the atmosphere? What is the function of the atmosphere? The atmosphere is layers of gasses that surround the Earth. Earth’s atmosphere has two main functions: 1st it contains gas like O2 that we need to live and 2nd it traps heat so the water on the planet remains liquid. Yellow Paper Title The Atmosphere

  3. What gases are in the atmosphere? There are 2 main gases in the atmosphere 1st Nitrogen 78% 2nd Oxygen 21%. All other gases make up the other 1%. The Atmosphere

  4. What is air Pressure? What is Barometric pressure? The result of the weight of a column of air pushing down on an area. Changes in the atmospheric pressure as shown by a barometer Green Air Pressure

  5. What are the Properties of air? Altitude/Elevation How does altitude affect air pressure and density? Air has mass, density, and pressure. The distance above sea level. (the surface of the ocean) The higher the altitude the lower the air pressure and denisty The lower the altitude the greater the air pressure and density. Air Pressure

  6. How many layers are there in the atmosphere? There are 5 layers, the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, Blue TitleLayers of the Atmosphere

  7. Layers of the Atmosphere • Troposphere: - This is the layer we live in and the smallest layer • Temperature decreases as altitude increases 140 to - 76 degrees F • All weather happens here • This is the ONLY layer living things can live in • 16 km above sea level

  8. Layers of the Atmosphere Stratosphere: Temperature increases as altitude increases from -76 to 32 degrees F - Ozone layer found here, and weather Balloons • 50 km above the earth

  9. Layers of the Atmosphere • Mesosphere: - Temperature decreases to coldest point 32 to -130 degrees F. - Meteor Showers -50 to 90 km

  10. Layers of the Atmosphere Thermosphere: - Temperature increases 2700 degrees F - Aurora borealis (Northern lights), International Space Station, Space Shuttle stay in this layer. - 90 to 500 km from sea level

  11. Layers of the Atmosphere Exosphere: - Temperature Increases to 5000 degrees F - Satellites orbit here - 500 km + from sea level

  12. Air Mass: There are 4 types of air masses classified by temperature, and humidity. A huge body of air that has similar temperature, humidity, and air Pressure. Tropical: warm Polar: cooled Continental: dry Maritime: wet White titleAir Masses and air Fronts

  13. What is a Front? There are three main types of Fronts An area where air masses meet and don’t mix. Cold Front Warm Front Stationary Front White TitleAir Masses and Fronts

  14. Air Masses and Fronts • Cold Front: Cold air moves underneath warm air, forcing warm air to rise.

  15. Air Masses and Fronts • Warm Front: Forms when warm air moves over cold air.

  16. Air Masses and Fronts • Stationary Front: happens when a cold and warm air mass meet and don’t move.

  17. White Title

  18. White TitleWeather Factors • Radiation: the transfer of energy by electromagnetic waves • Conduction: heat transferred through a substance by the direct contact of molecules. • Convection Currents: the transfer of heat by the movement of a heated fluid.

  19. White TitleWeather Factors • Weather is caused by heat energy, moister, wind, air pressure. • The ozone layer absorbs powerful ultraviolet radiation from the sun. • Green house effect: process by which gases hold heat in the air. CO2

  20. White TitleWeather Factors • Temperature: the average amount of energy of motion of the molecules of a substance. • Heat: the transfer of energy from a hotter substance to a cooler one.

  21. Blue TitleWind • Wind: the horizontal Movement for air from an area of high pressure to an area of low pressure. • All wind is caused by differences in air pressure. • Wind is named by the direction from which it comes from.

  22. Blue TitleWind • Jet Stream bands of high-speed winds about 10km above earth’s surface. • Prevailing Westerlies: mid-latitude, wind that blow from West to East.

  23. Green TitlePrecipitation • Precipitation: any form of water that falls from the clouds and reaches Earth’s surface. (liquid or solid) • There are 5 common types of precipitation • Water • Sleet • Freezing Rain • Hail • snow

  24. Green TitlePrecipitation • Humidity: measure of the amount of water vapor in the air • Water vapor: water in the form of a gas • Moist air is more dense then dry air • Liquid water in more dense then water vapor • Warm air holds more water vapor then cold air
