Presentation Transcript

  1. Do Now • At your table, share some good things that have happened this week. • You do not need to write this down. • Make sure you have turned everything in (syllabus, 5 themes photos, paragraph, quiz corrections).

  2. Climate and Vegetation Regions September 7, 2012

  3. The Köppen Climate Classification • 3 letter system • First letter = temperature • Second letter = precipitation • Third letter = finer shades of temperature • Csa = Mediterranean • C = middle latitude temperature • s = summer dry • a = hot summers (as opposed to warm)

  4. The Köppen Climate Classification • A= Tropical (equatorial regions) • B= Deserts (arid, semiarid) • C= Mesothermal (mild winter) • D= Microthermal (cold winter) • E= Polar (always cold) • H= Highland (mountains, plateaus)

  5. Climate Regions

  6. Vegetation Regions

  7. Tropical Humid Climates (A) • 36% of Earth’s total surface • Consistently warm • Subcategories based on rainfall • Tropical rainforest • Tropical monsoon • Tropical savanna

  8. Climate: Tropical Rainforest • High rainfall all year • Surrounds Equator

  9. Vegetation: Tropical Rainforest • Region: surrounds Equator • Vegetation: tall trees, ferns, vines • Highest density of plant species • Animals: insects, amphibians, reptiles, birds • More animal species than all other biomes combined • Among most threatened biomes

  10. Climate: Savanna • Surround tropical rainforests • Rainfall: 35-70”/year • Desertification

  11. Vegetation: Savanna • Region: around tropical rainforests • Vegetation: grasses, scattered trees and shrubs • Animals: large grazing animals and predators

  12. Dry Arid / Semiarid Climates (B) • 33% of Earth’s total surface • Water deficits • Subcategories • Desert • Steppe

  13. Climate: Desert • Wide range in temperature • Hot at low latitudes • Variation at high latitudes • Variation in rainfall • < 10 inches/year • Desertification

  14. Vegetation: Desert • Vegetation: Cacti, small flowers, shrubs • Animals: birds, small predators, reptiles

  15. Climate: Steppe • More precipitation than deserts • Narrower range in temperatures • Grasslands • Transitions between deserts and humid climates

  16. Vegetation: Grasslands • Region: Central North America, parts of Africa, Australia, SE South America (Pampas) • Best soil on Earth • Vegetation: grasses, some trees and bushes • Animals: large grazing animals, burrowing animals, a few predators

  17. Mesothermal Climates (C) • 20 % of Earth’s surface • “Middle temperatures” • True seasons • Subcategories based on precipitation • Humid subtropical • Marine west coast • Mediterranean

  18. Climate: Humid Subtropical • Hot summer • Cold spells • Year-round precipitation

  19. Vegetation: Temperate Forest (Deciduous) • Region: Western Europe, East Asia, Eastern U.S. • Good soil for agriculture • Broad leafed deciduous trees: oaks, hickories, maples • Animals hibernate and migrate

  20. Climate: Mediterranean • Surrounds Mediterranean Sea • Dry summers • Parts of Australia, South Africa, and Chile

  21. Vegetation: Mediterranean • Region: west coast and central California, SW. Australia, tip of South Africa, West Peru, Chile, Mediterranean • Vegetation: grassland, scattered trees, shrubs • Valuable for agriculture • At risk for fires, erosion, and desertification

  22. Microthermal Climates (D) • Almost entirely in the Northern Hemisphere • Humid continental

  23. Climate: Humid Continental • Long, cold winters • Moderate precipitation • Large temperature range

  24. Vegetation: Coniferous Forest • Region: northern parts of North America, Europe, Asia, South America, New Zealand, southern Australia • Vegetation: coniferous trees (needle-leaved) • Animals: large herbivores, predators • Problems: acid rain, logging, oil drilling

  25. Polar Climates (E) • < 50°F all year • High winds • Surround North and South Poles • Subcategories • Tundra • Ice caps

  26. Climate: Tundra • Very low precipitation • 32-50°F

  27. Vegetation: Tundra • Region: North of the coniferous forest, high latitudes of northern hemisphere in a belt around the Arctic Ocean, near the coast • Permafrost • Vegetation: mosses, low grasses, small plants • Animals: small burrowing, migratory, some predators

  28. Climate: Ice Caps • < 32°F • Very little precipitation • North and South Poles

  29. Highland Climates (H) • Lower temperatures • More moisture • High winds
