3. Chapter 4 Global Climates and Biomes

4. 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.

5. 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

6. The point is

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

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

9. Goal #3 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)

10. 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.

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

12. 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.
