Atmosphere 1

  1. 1. Atmosphere Presentation –Period 1 Grade 8 Taconic Hills Central Middle School Science Class June 2009
  2. 2. Weather By Nick and Sara
  3. 3. Weather is all of the events in the atmosphere at a given time. Forms of weather are precipitation cloud types and temperatures. Clouds in the Troposphere Most Weather occurs in the Troposphere, the lowest layer of the atmosphere

  6. 6. The atmosphere surrounds Earth and protects us by blocking out dangerous rays from the sun. The atmosphere is a mixture of gases that becomes thinner • Troposphere until it gradually reaches space. It is • Stratosphere composed of Nitrogen (78%), Oxygen (21%), and other gases (1%). • Mesosphere • Thermosphere • Exosphere Scientists divide the Earth’s atmosphere into four main layers, classified according to changes of temp.

  9. 9. The atmosphere explained…  The atmosphere is made up of mixture of atoms and molecules of different kinds.  Nitrogen, Oxygen, Carbon dioxide, other gases, water vapor and particles of liquids and solids make up the atmosphere.  Nitrogen is the most abundant (78%)

  11. 11. Importance of the Atmosphere
  12. 12. The importance of the atmosphere  The Earth’s atmosphere makes the conditions on Earth suitable for living things. It contains oxygen and other gases needed to survive. Many living things affect the atmosphere, constantly changing with gases moving in and out of living things, land and water.

  15. 15. Air consists of atoms called molecules which have mass. Because air has mass, it also has other properties, including density and pressure. Air pressure can change from day to day. Air pressure is the result of the weight of a column of air pushing down on an area. The force pushing down on an area or surface is known as pressure.

  17. 17. Measuring air pressure
  18. 18. Measuring air pressure  A barometer is an instrument that is used to measure air pressure. Two common kinds of barometers are mercury and aneroid barometers.  Mercury barometer-a glass tube open at the bottom end and partially filled with mercury. Greater air pressure forces the column of mercury higher.  Aneroid barometer- an airtight metal chamber without liquid. When air pressure increases, the thin walls of the chamber are pushed in.

  20. 20. BY: Brandon and Justin
  21. 21. Air pressure is measured with a barometer. There are two kinds of barometers; a aneroid barometer and mercury barometer. Air pressure decreases as density decreases as altitude increases. The higher you are, the harder it is to breathe because there are fewer air molecules.

  23. 23. Troposphere Harold & George
  24. 24. About the Troposphere The troposphere is the layer of the atmosphere that we live on. This is also where Earth’s weather occurs. It’s the smallest of all the layers @ 14km. Troposphere

  26. 26. Stratosphere
  27. 27. Stratosphere  Extend from the top of the troposphere to about 50 kilometers above the Earth’s atmosphere.  Second layer of the atmosphere and contains the ozone layer.  Lower stratosphere is cold, around -60 C and upper stratosphere is warmer than the lower stratosphere  The ozone layer protects the Earth’s living things from dangerous ultraviolet radiation from the Sun.

  29. 29. Mesosphere
  30. 30. Mesosphere  Above the stratosphere, a drop in temperature starts the beginning of the mesosphere.  “Meso” means middle  This layer protects the Earth’s surface from being hit by most meteoroids.  Begins 50 km above Earth and ends @ 80 km

  33. 33. Thermosphere The outermost layer of the atmosphere. Extends from 80 km above Earth’s surface and has no definite outer layer. “thermo” means heat. Up to 1800 Celsius and a very thin layer, due to the sunlight hitting this layer first
