Colour changing Hill ?

Ever wonder how it would seem to be when a hill could change it’s colour ? There’s one such hill known as the Ayer’s Rock. It changes its colour everyday and every season. It is 440 km south west in Australia. It is 338m high and 10km wide in base.


Normally it is red in colour, and the colour changes occur during the sunrise and sunset. During sunrise, it looks deep red in colour and during sunset it looks orangish yellow and at times looks black.



This spectacular phenomenon is possible because the Ayer’s rock is made up of sandstone. During sunreise and sunset, it looks orangish and redish because the lower wavelengths are scattered by the dust particles. It has been converted into a National Park to attract tourists.
