  • Soils develop in response to climate and vegetation.
  • Glaciers and a sub-arctic ecosystem are found in Denali National Park and Preserve.
  • The soil is well-drained (unlike the Arctic tundra).
  • Winter storms from the Pacific nourish many West Coast annuals, while well-developed summer monsoons host both annuals and woody plants originating from the south.
  • These coastal regions have cold ocean currents offshore.
  • North america

    1. 1. North America  Made By :Kausar Shaikh
    2. 2. Where is North America?    North America is to the north of South America. North America has the Pacific Ocean on the western side and the Atlantic Ocean on the eastern side. The cold Arctic Ocean is to the north of North America
    3. 3. Countries in North America     USA (our country) Canada Mexico Many other small countries
    4. 4. People in North America      There are many different kinds of people living in North America The first people in North America were called Native Americans or American Indians. There are still Indians living in North America today. All other people living in North America once came from other continents People in North America have many different skin and hair colors Most people in North America speak English, Spanish, or French
    5. 5. Weather in North America   The weather or climate in North America is very cold in the North like Canada, Alaska, and Greenland The southern parts of North America like Florida and Mexico are much warmer because they are closer to the equator
    6. 6. Animals in North America  One very special animal that lives in North America is the buffalo or bison. It lives on the flat prairie in the middle of North America.
    7. 7. Climate map Temperature and precipitation are its most important expressions and vegetation is its most visible expression. Animal life adapts to both climate and vegetation.
    8. 8. climate average condition of the weather based upon statistics collected over a period of 30 years. A climograph that combines monthly precipitation and temperature statistics on a single graph. Precipitation is shown using a bar graph and temperature is shown using a line graph. Climate influences vegetation, soils, landforms, and water resources, and many human activities as well. A climate region is a portion of the earth's surface over which the climate characteristics are similar.
    9. 9. Precipitation Rainfall amounts in North America range from over 150 cm in the rain forests to less than 50 cm in the mountainous areas of the West.
    10. 10. Population Map Which part of the United States is the most heavily populated?
    11. 11. Night lights Based upon satellite measurements of city lights, this image is a map of the urban population density of North America. Black – sea level, Light Gray – over 10,000 ‘ Most major cities are in level areas along an ocean, bay, large lake, or navigable river.
    12. 12. Land cover Vegetation types that cover the United States in different colors. Each land cover type plays a different role in carbon, climate, and water cycles. Land cover maps help scientists understand how human and natural activities affect the Earth system.
    13. 13. Snow Cover
    14. 14. Tundra The earth’s coldest biome The Arctic tundra is a cold, vast, treeless area of low, swampy plains in the far north around the Arctic Ocean. It includes the northern lands of Alaska and Canada. Since the sun does not rise for nearly six months of the year, it is not unusual for the temperature to be below -30°F in winter.
    15. 15. Alaska’s denali The Alaskan denali is a treeless tundra with only mosses and lichen vegetation in the summer, and covered with snow the rest of the year.
    16. 16. Alaska wildlife The Brown Bear (right) lives throughout the North American continent, particularly in the colder climes. Arctic birds converge along the islands
    17. 17. The southern part of the denali tundra gives way to the hardy trees of the taiga
    18. 18. Taiga Taiga (or Boreal Forests) represent the largest terrestrial biome. Occurring between 50° and 60° north latitudes, boreal forests can be found in the broad belt of Eurasia and North America. At left is the hardy jack pine species common in the poor, sandy soils, mostly in Canada.
    19. 19. Moose Moose
    20. 20. N Lake Effect L. Huron L. Ontario L. Superior L. Erie Detroit Milwaukee L. Michigan Chicago Convection
    21. 21. Marine West Coast The marine or humid west coast climate is found on the west coast of midlatitude climates and is very humid through most of the year. Westerly winds from the ocean bring cloudy skies, much precipitation, and mild temperatures.
    22. 22. Orographic Rain
    23. 23. West Coast rain forest The abundant rainfall of the Pacific Northwest allows for the growth of huge pine trees.
    24. 24. Olympia National Park Rivers carry nutrients to the forests by way of fish, insects and other animals that live in this aqueous world.
    25. 25. Alpine tundra Rocky Mountain high This biome exists at the tops of high mountains, above the tree line. The growing season is about 180 days, and nighttime temperatures are usually below freezing.
    26. 26. Deciduous Forest Deciduous forests can be found in the eastern half of North America, and the middle of Europe.
    27. 27. Great Plains grasslands Mid-grass prairie near Manhattan, Kansas Temperate grasslands are characterized by hot summers and cold winters. Evaporation rate is high, so little rain makes it into the rich soil.
    28. 28. Great Plains In the Prairies ecozone, rivers and streams are slow moving, usually with muddy bottoms. There are few lakes, but many marshes and small shallow ponds.
    29. 29. Desert Although most deserts occur at low latitudes, cold deserts occur in the basin and range area of Utah and Nevada. sparse vegetation, very low plant diversity
    30. 30. Sonoran Desert This is the hottest of our North American deserts, its rainfall pattern produces a high biological diversity. The Sonoran Desert is an arid region covering 120,000 square miles in southwestern Arizona and southeastern California, Baja California and the western half of the state of Sonora, Mexico.
    31. 31. Californian chaparral A chaparral is a shrubby coastal area that has hot dry summers and mild, cool, rainy winters. Annual rainfall in a chaparral ranges from 15– 40” per year. The word chaparral comes from "chaparro," which means scrub oak in Spanish.
    32. 32. Rain forest Tropical rain forests are mainly the product of climatic interactions, particularly temperature and rainfall. They occur where monthly temperature of 20 - 28°C combines with an annual rainfall of 1.5 -10m, evenly distributed throughout the year.
    33. 33. Central American Rain Forest The tropical rain forest is a forest of tall trees in a region of year-round warmth with an annual average of 50- 260” of rain. These forests belong to the tropical wet climate group.
