How can floods in one place and droughts in another be connected, such as in Kenya in 2003? 2. What is the difference between weather and climate? 3. What two factors primarily determine which organisms can live in an area? There are 7 major components to the distribution of heat and precipitation (and thus climates) on Earth: I. Earth’s Atmosphere 4. Explain why atmospheric pressure decreases as altitude increases. 5. Identify which of the 5 layers of Earth’s atmosphere fit each description in the table: Troposphere Exosphere Aurora Borealis (northern lights) occurs here Atmospheric pressure is highest here All weather occurs here Atmospheric pressure is lowest here Atmospheric temperatures are highest here Contains the ozone layer Layer closest to the surface Densest layer of the atmosphere Outermost layer of the atmosphere Temperature is around 20° at this layer’s lowest point The lowest pressure is found in this layer 6. The chemical formula for ozone is _______ and its function is to ______________________ II. Unequal Heating of Earth 7. Explain how each of the following factors creates unequal heating of Earth’s surfaces: a. Angle of sun to surface: b. Solar rays per unit area: c. Albedo: 8. How will the melting of polar ice from global warming alter Earth’s albedo? 9. Generally speaking, the _________ regions of Earth receive the most light/heat in a year and the _________ regions receive the least light/heat in a year. III. Atmospheric Convection Currents 10. Explain why warm air rises and cool air sinks. 11. Why is rising air associated with precipitation? 12. What types of atmospheric conditions are found where air sinks back to the surface? 13. Draw each of the following on the diagram below: Earth’s atmospheric convection cells, with direction of air movement The general level of precipitation found at each latitude belt: 0/30/60/90) 14. Why does the ITCZ move throughout the year in a regular pattern? IV. Earth’s Rotation and the Coriolis Effect 15. The Coriolis Effect deflects moving objects (such as wind) in a ________ direction in the northern hemisphere and a _____________ direction in the southern hemisphere 16. Draw arrows indicating the general direction of wind movement between latitudes : V. Earth’s Tilt and Seasons 17. In Los Angeles, the longest day of the year occurs in the month of ___________ because __________________________________________________________________ 18. Why does the northern hemisphere’s summer come during the southern hemisphere’s winter, and vice versa? VI. Ocean Currents 19. What are gyers, and how are they created? 20. Explain how oceanic gyers and atmospheric convection currents redistribute heat around Earth. 21. Upwelling is a process in which _________________________ water is brought to the surface along a coast. It is caused by ____________________________ and is important to humans because _______________________________________________________. 22. Describe what thermohaline circulation is, and how it transports heat. 23. The ENSO is a disruption to _________________________________ in which warm water and increased precipitation build up in the region of _________________________ while drought and cold water occur in the region of _______________________________ VII. Rain Shadows 24. What is the difference between the windward and the leeward sides of a mountain range? VIII. Summary 25. The Earth’s atmosphere and oceans can be thought of as a single “heat engine” system that transfers heat around the globe. Explain how the atmospheric/oceanic system circulates heat, including where heat is distributed from and to. 26. Summarize why latitude is so important in determining climate: Variations in climate determine the dominant plant growth forms of terrestrial biomes. Aquatic biomes are characterized by salinity, depth, and water flow Working Toward Sustainability: Is Your Coffee Made in the Shade? 1. What are climatograms and what do they show? 2. What are the main constraints for the growing season for plants in a given biome? Complete the following biome chart for terrestrial biomes: Terrestrial Biomes: Tundra Boreal Forest Temperate Rainforest Temperate Seasonal Forest Shrubland (Chaparral) Temperate Grassland Tropical Rainforest Tropical Season Forest Subtropical Desert General Global Location Annual Weather Patterns Notable Soil Characteristics Distinguishing Species Complete the following biome chart for aquatic biomes: Aquatic Biomes: Defining characteristics Ecological importance: Streams & Rivers Lakes & Ponds Freshwater Wetlands Salt Marshes Mangrove Swamps Intertidal Zone Coral Reefs Open Ocean Is Your Coffee Made in the Shade? 3. Why is shade-grown coffee better for the environment? 4. How has coffee production changed to help minimize the problems with pest control?
