G10 natural regions Presentation Transcript

  • 1. NATURAL REGIONS What are natural regions? www.StudsPlanet.com
  • 2. Definition Natural region is an area of earths surface which is essentially homogenous with respect to the conditions that effect human life -Prof. Herbertson www.StudsPlanet.com
  • 3. Natural Regions • Countries along the equator share a similar kind of climate • Hence certain areas in different parts of the world have almost identical climate, vegetation, animal life and human occupation. • Climate is the most important factor influencing vegetation, soil, animals and mode of human life www.StudsPlanet.com
  • 4. Natural Regions • It is possible to divide the world into a number of regions on the basis of climate- areas grouped in each region have similarities of climate, vegetation, animal life, human occupation and products. www.StudsPlanet.com
  • 5. Advantages of studying natural regions • Studying fewer climatic regions is far easier and far more interesting than studying numerous political units • A study of this nature is more logical • Study of natural regions helps in understanding differences in industrial and commercial development • Appreciates the natural pattern of trade www.StudsPlanet.com
  • 6. Disadvantages of studying natural regions • Physical conditions are never fully identical in two widely separated areas • Places belonging to a particular natural region need not have all the conditions in common • Natural regions are not water tight compartments • There is no sharp line which divides one region from another www.StudsPlanet.com
  • 7. Disadvantages of studying natural regions • Changes from one natural region to another is often gradual and not abrupt • Classification based on climate is an approximation-they have more resemblances than differences • Inclusion of an area in one natural region or another is sometimes debatable Ex-Sri Lanka is equatorial but can be included in monsoon region due to high rainfall www.StudsPlanet.com
  • 8. Major Natural Regions There are 5 major regions: 1. Equatorial Region (within 5 degrees) a) Equatorial Low Land Region or Amazon Type b) Equatorial High Land Region or Ecuador Type www.StudsPlanet.com
  • 9. 2. Tropical Region (within 5-30) 1. Tropical Monsoon – Monsoon Type 2. Tropical Grassland – Sudan Type 3. Tropical Dessert – Sahara Type 4. Tropical Rain Forest – Caribbean Type www.StudsPlanet.com
  • 10. 3. Warm Temperate Region (between 30-45) a) Warm Temperate West Marginal Region-Mediterranean Type b) Warm Temperate East Marginal Region-China Type c) Warm Temperate Desert Region www.StudsPlanet.com
  • 11. 4. Cool Temperate Regions (45-60) a) Cool Temperate Oceanic Region – West European Type b) Cool Temperate East Marginal Region – St Lawrence Type c) Cool Temperate Grassland Region – Prairie Type www.StudsPlanet.com
  • 12. 5. Cool Temperate and Polar Regions (> 70 degrees) a) Coniferous Forests Taiga Type b) Cold Desserts or Tundra Type www.StudsPlanet.com
