2. Weather The condition of Earth’s atmosphere at a particular time and place. By: Zoe & Jasmine

3. Weather occurs in the Troposphere. Rain, snow, and most clouds occur here. The first weather satellite was launched in 1960. The burning of fossil fuels creates smog and acid rain. Weather Information

11. IMPORTANCE OF THE ATMOSPHERE By: Christian

12. Atmosphere The Earth's atmosphere (or air )- is a layer of gases surrounding the planet Earth that is retained by the Earth's gravity 78.08% nitrogen , 20.95% oxygen , 0.93% argon , 0.038% carbon dioxide The atmosphere protects life on Earth by absorbing ultraviolet solar radiation , warming the surface through heat retention

14. Properties of Air Introduction to By: Nathan

15. Explanation Air has mass because it has atoms and molecules, which have mass. Density= mass of a substance in a given volume Pressure is the force pushing in an area or on a certain substance. Air pressure is when weight of a column of air pushes down on an area. Air pushes in all directions. Density volume = Mass

17. MEASURING AIR PRESSURE by: Chris

18. A barometer is how you measure air pressure by mercury, which contains vacuum mercury. The aneroid barometer which contains vacuum chamber, lever, spindle and pointer.

20. Altitude and Properties of Air

23. Troposphere

26. Introduction into the Stratosphere The Stratosphere supports bacteria life, making it part of the biosphere. The Stratosphere is the second layer of Earth’s atmosphere. The temperature increases as altitude increases. The region of the atmosphere above the troposphere and below the mesosphere. The stratosphere is almost always free of clouds and all other forms weather. Karlee and Nicole:]<33

27. Explanation of the Stratosphere In the Stratosphere, the air doesn’t flow up and down, but it flows parallel to the earth in very fast moving air streams. This is the layer where most jet planes fly. The stratosphere starts at around 10 kilometers and goes to about 50 kilometers high. The top edge of the stratosphere is abundant with ozone. Ozone is the by-product of sun radiation and oxygen; by capturing the ultraviolet rays of the sun and deploying it, ozone takes out the harmful effects. This is very important to all living things on earth, since unfiltered radiation from the sun can destroy all animal tissue.

29. The Mesos phere Pat/Garret

30. In the Earth's mesosphere, the air is relatively mixed together and the temperature decreases with altitude. The atmosphere reaches its coldest temperature of around -90°C in the mesosphere. This is also the layer in which a lot of meteors burn up while entering the Earth's atmosphere. The mesosphere is on top of the stratosphere The upper parts of the atmosphere, such as the mesosphere, can sometimes be seen by looking at the very edge of a planet

32. Thermosphere

35. IONOSPHERE the part of the earth's atmosphere beginning at an altitude of about 50 kilometers (31 miles) and extending outward 500 kilometers (310 miles) or more Casey & Robert

36. Ionosphere: The ionosphere is part of the thermosphere. It is made of electrically charged gas particles (ionised). The particles get this electric charge by ultraviolet rays of the sun. The ionosphere has the important quality of bouncing radio signals, transmitted from the earth. That’s why places all over the world can be reached via radio.

47. Acid Rain and Smog By. Jessica and Lizzie

48. Acid rain is a mixture of wet and dry composition. Occurs when SO2 and NOx when they mix together with water and oxygen and other chemicals to form different compounds. Acidification can cause trees or others on high elevations to become damaged. Acid Rain Smog Classic smog: is the most basic form and is the result of burning of fossil fuels. The weather that comes with smog is stagnant winds and when the hot air presses with the cold air below. The term smog was founded in 1905 by when Harold Antoine des Voeux wanted to name the heavy fog in London.
