1. Weather Notes and Voc. 1.voc Meteorology: the study of the weather, atmosphere, and weather forecasting. 2.voc Weather: the present condition of the atmosphere 3. voc Climate: general condition of the weather over a period of time (seasons) 4.Describe at least 3 ways that Benjamin Franklin created the process of gathering weather data. 5. Predicting the weather is still NOT a precise science. Explain what this statement means.

2. 6.What invention prompted scientists to start to collect weather data? 7.voc atmosphere: the layer of air that surrounds the earth’s surface 8.The 5 main layers of the atmosphere are: (all voc) Exosphere: the outermost layer of the atmosphere Thermosphere: above the mesosphere (contains the ionosphere) Mesosphere: Layer just above the stratosphere> Stratosphere: Layer above the troposphere Troposphere: The layer of the atmosphere closest to earth.

3. 9.Air is made of 78% __________, 21%________ and 1% ______. 10.The physical properties of air are measured by: Voc temperature- how hot or cold Voc density – the amount of matter in an object (drawing) Voc pressure –measure of force of air pressing down on Earth’ 11.Air pressure decreases as altitude increases. 12.The greenhouse effect allows living organisms to survive on Earth and provides a “heat blanket” around the Earth. (leave space to draw illustration) 13.Earth’s atmosphere is constantly changing. 14. Human Activity can change Earth’s atmosphere, for example the burning of fossil fuels and air pollution.

4. 15. Nature vs Human Pollution wildfires cars volcanoes burning materials CFC’s floods pesticides Acid Rain 16. Ozone : Good or Bad In stratosphere: ozone is natural and GOOD In troposphere: ozone is harmful and acts a greenhouse gas- also increases breathing problems- overtime temperatures increase and organisms can die (drawing from sci-tech) 17. How to Help ?? More fuel efficient cars Ban CFC’s and other chemicals Develop alternative energy sources

5. Weather Vocabulary Weather climate atmosphere thermosphere (ionosphere) Air pressure density stratosphere exosphere Altitude greenhouse effect ozone temperature evaporation condensation precipitation runoff Conduction convection global winds trade winds

6. 18.Know these voc. Words Hydrosphere- all of the liquid water in the world (lakes, oceans) Cryosphere- all of the frozen water in the world( glaciers, polar caps) Lithosphere- all of the land forms on Earth Geosphere- all of the land forms, water, atmosphere in the world Water cycle- the movement of water which involves evaporation, condensation, and precipitation- this cycle never stops 19.The Water Cycle- influences weather patterns Climate, temperatures, biomes 20. Water Drop Odyssey 19.The energy from the sun causes wind and water currents on Earth to move from place to place. 20.Land heats up and cools down more quickly than water. Example- at the beach sand is hot and water is cool This effects the temperature of the air near the land and water.

7. 21. The energy from the sun causes wind and water currents on Earth to move from place to place. 22. Land heats up and cools down more quickly than water. Example- at the beach sand is hot and water is cool This effects the temperature of the air near the land and water. 23. The Rain Man Water is always ______________________. List 3 facts from the story. 24. Voc Humidity- the amount of water vapor in the air
