2.1 revision #1 2013

  1. 1. 2.1 – Amazonia Revision
  2. 2. Aspects are selected from: • • the characteristics of a large natural environment • • how the elements and processes of the large natural environment interact • • how a large natural environment is formed and changes over time • • how people interact with a large natural environment • • how people's perceptions of a large natural environment change over time.
  3. 3. 3000km
  4. 4. Maps • Draw 4 maps • On each map draw – frame, outline of South America and Amazonia. – North arrow – Scale (3000km from mouth to Andes) • Maps to draw are – – – – – Soils Vegetation Climate landforms
  5. 5. Specifics • Iquitos, Manaus, Belem • Guiana Highlands, Brazilian Highlands, Amazon Basin, Andes mountains • Alluvial Soils, Latosols • Savannah, Evergreen, Seasonal • Convectional rainfall, Orographic rainfall, Coastal Rainfall • 3000km from mouth of River (Belem) to Andes • ITCZ
  6. 6. Describe the characteristics • • • • For each map – Say what the map shows you Do Not use the word ‘because’ Each description should say what the pattern is. Eg around the river is found an area of alluvial soils this area is known as the varzea or floodplain. These soils are fertile and well drained they are high in nutrients.
  7. 7. Explain the characteristics • You now need to give reasons (processes and elements) WHY the patterns exist. • This question asks to show the marker that you know why the landscape is like it is now. • Elements = soils,rainfall, wind, trees, rock type • Processes = volcanism, orographic rainfall, fluvial erosion
  8. 8. Reasons for Landforms • Gondwanaland broke up 250mya • Continents drifted on Subduction currents to current location • Subduction occurs to form Andes (Nazca and Sth American) 90mya • Andes make river flow to the East and erodes the central area to form the Amazon River basin • The Areas of the Brazilian and Guiana highlands are hard rock so not eroded by the river. • River slows at the mouth so deposits material to form a delta 300 km wide.
