Why is most of Australia desert?

The main reason for the formation of the Australian deserts is their location. Like most major deserts across the world the Australian deserts can be found around a certain latitude (roughly 30° north/south of the equator) where the weather phenomena create a dry climate: Hot moist air rises at the equator.

Does anyone live in the middle of Australia?

What makes Australia a dry country?

Australia is the second-driest continent in the world, with mean annual rainfall less than 600mm for more than 80 per cent of Australia. Australia is so dry because we sit under the subtropical high-pressure belt, which encourages the air to push down, preventing the lift required for rain.

Why is Australian desert red?

In warmer climates, like Australia, chemical weathering is more common. Chemical weathering occurs when conditions change the materials that make up the rock and soil. As the rust expands, it weakens the rock and helps break it apart. The oxides produced through this process give the ground its reddish hue.
