Why is australia so flat and dry
Year 10 GeographyInvestigating Australia’s Physical Environments
Population of 22.8 million Australia 6th largest country on Earth by area.Approximately 7682 millionsquare kilometres.
Australia is the Flattest and Driest inhabited Continent on Earth
Australia’s size and shape contribute considerably to its dryness.
TopographyNo significant landforms/mountains results in limited Orographic rainfall.
ContinentalityGenerally, rainfall decreases as you move away from large bodies of water (i.e Oceans) Rain bearing winds from the coast can’t make it to the interior.
Prevailing Winds and Ocean Currents Prevailing winds come from the South West.These pass over cold ocean currents, which do not allow for evaporation. Low precipitation
What does all this mean?The physical geography has a monumentaleffect on the natural and humanenvironment. Provide some examples?- The environments that exist- Flora and fauna- Inhabitability, distribution of people, location of cities- Land use and agriculture
