1. bv 1.Turn in the webquest (if didn’t last class) 2.Quiz: Basics of Atmosphere 3.Finish lab graph and questions & turn it in. 4.Land vs. Sea Breezes Learning Goal: Describe the factors that cause the unequal heating of the Earth’s surface and how that affects the atmosphere Agenda 11/21/13

2. bv 1.Unequal Heating of the Atmosphere 2.What causes that? 1.Topography (different surfaces) 2.Latitude 3.Elevation 4.Distance from large body of water 5.Tilt of Earth’s axis (seasons) 6.Pollution * These can affect density of air masses and that causes wind to blow from high pressure to low pressure. What Causes Wind?

3. Sea and Land Breezes L H H L

4. Video: History of Wind Power Link to video Fill out the worksheet as you watch the video.

5. A surface that is VERY reflective…. Ice, snow What type of surface has a high albedo?

6. What is weather? the process by which energy in the atmosphere is being balanced out. As long as more energy keeps coming into the atmosphere, it never gets completely balanced, so we continuously have weather. What is necessary for weather? 1.An atmosphere 2.A source of energy to the atmosphere 3.An unequal distribution of energy in the atmosphere

7. bv 1.Type of surface, and albedo 2.Elevation 3.Latitude 4.Seasons 5.Urbanization 6.Pollution What Factors Influence Atmospheric Temperature?

8. 23.5° (tilt) 0° Equator 70° Latitude 30° Latitude 60° Latitude Reason for the Seasons 90 o Latitude Because the surface of the Earth is curved, certain portions receive direct rays and other portions receive indirect rays

9. Reason for the Seasons As the angle increases, the amount of land that is receiving solar radiance also increases. The area increases, but the amount of solar radiance is the same This means that the energy becomes less concentrated as the ray becomes less direct.

10. because the predominant ray is …. Winter Solstice December 21 Summer Solstice June 21 Fall (Autumnal) Equinox September 21 Spring (Vernal) Equinox March 21 SUN In-direct on the… Direct on the… Equal on the… In the northern hemisphere… the season is…. Winter Fall Summer Spring
