  3. Chapter 4 Global Climates and Biomes

  4. Interact with your notes • 1.Explain the concept of “Albedo” • OR • 2. Gives me two examples of processes that occur in the air

  5. Weather and Climate • Weather- short term conditions of the atmosphere in a local area. Includes: temperature, humidity, clouds, precipitation, wind speed and atmospheric pressure. • Climate- average weather that occurs in a given region over a long period- typically several decades.

  6. Evidence for changes in climate • Tree rings • Fossilized plants • Insect and pollen samples • Gas bubbles in glaciers • Deep ice core samples • Lake sediments • Dust analysis • Isotope ratios in fossilized remains

  7. The point is

  8. What affects an areas climate? • LAWT-O! • Latitude (distance from the equator) • Altitude (height above sea level) • Winds • Topography (shape and location of land) • Ocean Currents

  9. Goal #1Earth's Atmosphere • What are they? • What are their characteristics? • Explain reasoning behind their temperature change.

  10. Goal #2 Unequal Heating of Earth • The variation in angle at which the Sun's rays strike • Some areas of Earth reflect more solar energy than others. (Albedo)

  11. Goal #3Wind and Convection Currents • Air moves! • Why? • How does this affect regional climate?

  12. Earth's Rotation and the Coriolis Effect • As Earth rotates, its surface moves much faster at the equator than in mid-latitude and polar regions.

  13. Goal #3 continued…Global Winds!! • Coriolis Effect- the deflection of an object's path due to Earth's rotation. • The prevailing winds of the world are produced by a combination of atmospheric convection currents and the Coriolis effect.

  14. Station Learning Experience! Layers of Atmosphere Layers of Atmosphere Layers of Atmosphere Albedo Albedo Albedo Wind Wind Wind

  15. Review your handouts • Examples – explain convection and high low pressure • The type of climate associated with high low climate • Study global wind diagram • Study layers of atmosphere diagram

  16. 1. In which layer of the atmosphere does more weather occur? • A. Troposphere • B. Stratosphere • C. Mesosphere • D. Thermosphere • E. Lithosphere

  17. 3. Low pressure area is associated with • A. hot and humid weather • B. fair weather • C. tornadoes • D. cloudy and stormy weather • E. hurricanes

  18. 5. Population of predator and prey. If the numbers of prey decrease, then the some predators starve and their population numbers will decrease until it reaches the carrying capacity for food source • A. positive feedback loop • B. negative feedback loop

  19. 1. In which layer of the atmosphere does more weather occur? • A. Troposphere • B. Stratosphere • C. Mesosphere • D. Thermosphere • E. Lithosphere

  20. 3. Low pressure area is associated with • A. hot and humid weather • B. fair weather • C. tornadoes • D. cloudy and stormy weather • E. hurricanes

  21. 5. Population of predator and prey. If the numbers of prey decrease, then the some predators starve and their population numbers will decrease until it reaches the carrying capacity for food source • A. positive feedback loop • B. negative feedback loop

  22. What’s your DOT? • Do One Thing To help the environment today

  23. 2. Climate is influenced by • A. the amount of incoming solar radiation. • B. Earth's rotation. • C. the tilt of Earth's axis. • D. all of these answers.

  24. 4. Ozone • A. in the stratosphere is a pollutant. • B. is formed in the stratosphere through the interaction of infrared radiation and molecular oxygen. • C. filters out all harmful ultraviolet radiation. • D. in the stratosphere forms a thermal cap important in determining the average temperature of the troposphere.
