Australia in Asia and the PacificPhysical Geography
Definitions
Relief
Landform
Topography
Plains Areas of lowlands with gentle slopes and
low hills Sometimes associated with river
systems Alluvial soil deposited during flooding of
rivers over centuries produces rich, fertile soil
Majority of people live here Support intensive agriculture
ExamplesIndo-Gangetic Plain Kanto Plain
Structural PlainsExample: Inner China No deposits of alluvial soil Severe climate No potential for agriculture
Hill Lands/Uplands Moderate elevation India and China hill lands are plateaus Most productive agricultural land
consists of pockets of alluvium along the valley floors
China south of Yangtze River mainly hill lands
ExampleIndia
Mountains and Plateaus Main areas are around Pakistan and
India Ranges radiate from Pamir Mountains in
northern Pakistan and Afghanistan Continue south easterly direction
through SE Asia, Indonesia and PNG World’s highest mountain: Everest
8848m, 93 other mountains over 7300m
Mountains and Plateaus Soil is shallow and will not grow enough
crops to support a lot of people Scattered, isolated villages Broken by deep river valleys Mountains act as a barrier to movement
and communication, divide countries from each other and form a natural line of defence
Examples
Rivers Focus of human settlement Deposits of alluvium created favourable
conditions for intensive agriculture Outside of main rivers catchments are
generally too small to create extensive flood plains
Rivers act as international boundaries, transport routes, irrigation water
ExamplesMekong Cambodia
Deltas Triangular shaped area of land at the
mouth of a river with large deposits of alluvium
ExamplesGanges River Delta - Bangladesh
Islands Many countries that consist solely of
islands, eg: Indonesia, Japan, Philippines, New Zealand, Pacific islands
Travelling between islands difficult Goods and people transported by boat Isolation
Examples
Pacific IslandsMelanesiao Islands lie along edge of Australian
tectonic plateo Made from fragments of land that were
once part of GondwanaPolynesiao Islands are result of volcanoes that have
risen from a hot spot on the sea flooro Surrounded by coral reefs
