Answer:
The Australian Great Dividing Range creates a rain shadow on the country’s eastern coast and interior.
Explanation:
The Great Dividing Range lies in eastern Australia, in the states of Queensland, New South Wales and Victoria. The mountains are built mainly of sandstone, granite and basalt. To the east, they fall steeply towards a narrow strip of coastal lowlands, while to the west they descend gently towards the Central Australian Lowland.
Lush savannas and mainly eucalyptus forests grow on the eastern slopes, while western slopes are dry savannas. This is because the Great Dividing Range acts as a climate barrier between the humid east side of Australia and the dry west side, thus acting as a rain shadow.
The Great Dividing Range has the sources of Australia's largest rivers Murray and Darling. The main ridge is the watershed between the Pacific Ocean catchment in the east and the Indian Ocean catchment and the valley of Lake Eyre in the west (hence the name of the mountains).
