2. Oceans Exam data

3. The Atmosphere It’s time to move up in the world! Update your table of contents!!

4. The Atmosphere As you view this time-lapse video write down 3 things that occur in the Earth’s atmosphere. http://www.youtube.com/watch?v=O3L6p1zDs6k

5. Atmosphere: the layer of gases that surrounds Earth. The Atmosphere

6. Air is a combination of gases and solid particles. Atmospheric Composition

7. Earth’s atmosphere consists mainly of nitrogen (78%) and oxygen (21%). The amounts of nitrogen and oxygen in the atmosphere are fairly constant over time. Atmospheric Composition

8. The concentrations of some atmospheric gases are not as constant over time as the concentrations of N and O. Water vapor Carbon Dioxide Atmospheric Composition

9. During the past 150 years, the concentration of atmospheric carbon dioxide has increased. Carbon dioxide traps warm air in our atmosphere and leads to ….Global warming! Atmospheric Composition

10. What about the Ozone layer?? The ozone layer blocks harmful ultraviolet rays from reaching Earth’s surface. Molecules of ozone are formed by the addition of an oxygen atom to an oxygen molecule. O3 Atmospheric Composition

11. Earth’s atmosphere also contains solids in the form of tiny particles, such as dust, salt, and ice. Atmospheric Composition Very important to the water cycle!!

12. Atmospheric Layers The atmosphere is classified into five different layers: Troposphere Stratosphere Mesosphere Thermosphere Exosphere Inosphere

24. Bell Work 2/13/14 24 On your desk: 1. I.N. 2.Pencil/Pen 3.PRIDE Cards 4.iPad 1. What happens to the temperature in the Mesosphere as the altitude increases? The temperature in the mesosphere decreases. 2. What happens to the temperature in the stratosphere as the altitude increases? The temperature in the stratosphere increases.

25. Bell Work 2/14/14 25 On your desk: 1. I.N. 2.Pencil/Pen 3.PRIDE Cards 1.Write down one amazing fact about: Troposphere- Stratosphere- Mesosphere- Thermosphere-

26. Troposphere Tropo= “turning” or “change” As you increase in altitude, temperature decreases. As you increase in altitude, pressure decreases. Facts: 90% of the atmosphere’s total mass. Weather occurs here. Gases are constantly mixing.

27. Stratosphere Strato– “layers” As you increase in altitude, temperature increases. As you increase in altitude, pressure decreases. Facts: Gases are layered and don’t mix Ozone layer Air is thin and contains very little moisture.

28. Mesosphere Meso– “middle” As you increase in altitude, temperature decreases. As you increase in altitude, pressure decreases. Facts: Middle layer Coldest layer (-93 degrees C)

29. Thermosphere Thermo– “heat” As you increase in altitude, temperature increases. As you increase in altitude, pressure decreases. Facts: Atoms of N and O absorb high-energy solar radiation and release thermal energy. 1,000 degrees C or higher But… it does not feel hot! (temp is different from heat) Charged particles cause shimmering lights called auroras!

30. Exosphere Exo – “outside” or “beyond” As you increase in altitude, temperature decreases. As you increase in altitude, pressure decreases. Facts: The transitional region between Earth’s atmosphere and outer space Most satellites orbit in this layer.

39. You are lying in a park. Your eyes are closed, and you feel the warmth of the sun on your face…. Have you ever stopped to think that it takes a little more than 8 minutes for the energy that warms your face to travel from a star that is 149,000,000 km away?!

40. Where do we get our energy?? Yes…. The SUN!

41. How is energy transferred (moved) in the atmosphere?? Radiation Convection Conduction

42. Energy Transfer in the Atmosphere The Earth receives energy from the sun by radiation. Radiation is the transfer energy as electromagnetic waves.

43. Energy Transfer in the Atmosphere Only 2 billionths of the sun’s energy makes it to Earth! What happens to solar energy once it enters the atmosphere??? 25% is reflected by clouds and air 20% is absorbed by ozone, clouds and atmospheric gases. 5% is reflected by the Earth’s surface 50% is absorbed by the Earth

44. Energy Transfer in the Atmosphere Have you ever touched anything hot?? Conduction is the transfer of thermal energy between objects when their atoms or molecules collide.

45. When air molecules come into direct contact with the warm surface of Earth, thermal energy is transferred to the atmosphere. Energy Transfer in the Atmosphere

46. Convection is the transfer of thermal energy by the movement of heated material from one place to another.

47. Fill in the blanks!!! As air is heated, it becomes less __________and rises. Cool air is denser, so it ______________. As the cool air __________________, it pushes the warm air up. The cool air is eventually _______________ by the Earth’s surface and begins to ________again. This cycle of warm air _________and cool air ________________causes a circular movement of air, called a convection current

48. As air is heated, it becomes less dense and rises. Cool air is denser, so it sinks. As the cool air sinks, it pushes the warm air up. The cool air is eventually heated by the Earth’s surface and begins to rise again. This cycle of warm air rising and cool air sinking causes a circular movement of air, called a convection current Energy Transfer in the Atmosphere

51. It is time to Practice Use the text book (or online text) to complete the worksheet provided! Weather and Climate Chapter 1 Section 2

52. Warm-up 2/21/14 What are the three ways energy is transferred in the atmosphere? Radiation, conduction, and convection Where is the energy source during the process of conduction? The Earth’s crust

53. Demo: Cloud in a Bottle Materials: Plastic Bottle Warm Water Match Clouds and Precipitation Section 11.3

54. Demo: Cloud in a Bottle Clouds are formed when water droplets in the air cool and then collect on dust particles. In this demonstration, the dust particles were provided by the smoke from the match. The air inside the bottle was cooled by releasing the pressure after the bottle was squeezed. The temperature is changed by squeezing the bottle: the amount of air within the bottle is constant, but squeezing the plastic bottle changes the volume of the gas. Expanding the bottle causes a lowering of the air temperature – in this case, enough to cause the water gas to form a liquid – the cloud.

55. Cloud Formation Clouds in the atmosphere are formed the same way! Clouds are formed when air containing water vapor is cooled and moisture condenses into droplets on microscopic dust particles (condensation nuclei) in the atmosphere. The air is cooled by expansion during its upward movement.

56. Cloud Formation A condensation nucleus is a small particle in the atmosphere around which water droplets can form. When the number of these droplets is large enough, a cloud is visible. Clouds and Precipitation Section 11.3

57. Types of Clouds Clouds are generally classified by the altitudes at which they form and by their shapes. Latin RootMeaning Cumulus Stratus Cirrus nimbus Heap Layer Curl of hair rain

58. Types of Clouds Low clouds- Low clouds are of mostly composed of water droplets since their bases generally lie below 6,500 feet. Clouds and Precipitation Section 11.3 Middle clouds- they are composed primarily of water droplets,sometimes ice. The bases of mid-level clouds typically appear between 6,500 to 20,000 feet High clouds- High-level clouds form above 20,000 feet and since the temperatures are so cold at such high elevations, these clouds are primarily composed of ice crystals.

60. Precipitation The water cycle Water moves from Earth to the atmosphere and back to Earth in the water cycle.

61. Precipitation All forms of water that fall from clouds to the ground are precipitation. Rain, snow, sleet, and hail are the four main types of precipitation.
