2. Biomes Large-Scale Ecosystems Shaped by Global Influences

3. Radiant energy is supplied unevenly over the Earth’s surface

4. The Tropics of Cancer and Capricorn are the latitudes of the solar equator at summer and winter solstices

5. The average annual mean temperature is more variable in the Northern Hemisphere than in the Southern…Why?

6. Global map of oceans & continents

7. Relative Humidity varies with air temperature

8. Adiabatic cooling occurs as the onshore air flow is lifted over coastal mountain ranges

9. Worlds largest temperate rainforest

10. 1. Warmed air rises… …expands… …loses moisture… 2. Surface air from N & S replaces it 3. Dry air at altitude flows N or S 4. Descending air is even less likely to release moisture

11. Deserts Rainforests

12. Earth’s rotation produces different prevailing wind patterns at different latitudes

13. Winds and Earth’s rotation drive ocean currents. Continents block them

14. A variety of global influences produce similar climates in widely different places.

17. The Tropical Rainforest Biome Location: between 23.5º Nand 23.5º Slatitudes Annual Rainfall: 150-400 cm (60-160”) Mean annual temperature: 25˚-27˚C (77-80˚F) Mean annual evapotranspiration: 160 cm (63”)

18. CactaceaeEuphorbiaceae Residents of the same biome tend to resemble one another vegetational convergence

19. Among plants, natural viviparyis found only in unrelated mangrove species vegetational convergence

20. faunal convergence

21. AfricaSouth America faunal convergence

22. Biomes are large-scale ecosystems with distinctive vegetational characteristics that correspond to climate patterns
