Planet fantastic: Stunning images of the world's most breathtaking landscapes

They look like scenes straight out of the latest sci-fi blockbuster, futuristic landscapes from a distant alien world.
But this is planet Earth at its most magnificent, the spectacular quirks of mother nature that continue to astound and delight in equal measure.
From the vivid colours of a beautiful hot spring to a random rock formation that looks just like an elephant, the incredible landscapes have formed over millions of years.

The Wave: (Utah, USA) Carved rock eroded into a wave-like formation made of jurrasic-age Navajo sandstone that is approximately 190 million years old

The Beauty Pool: (Yellowstone National Park, USA) The hot spring allows luminous algae and bacteria to flourish creating a vivid array of colours

Another view of Beauty Pool in Yellowstone National Park. It is connected to a nearby pool called Chromatic Spring and when the water level in one rises, the water level in the other decreases

Take Beauty Pool, a much visited site in the Yellowstone National Park in Wyoming, where the hot spring has allowed algae and bacteria to flourish creating a staggeringly beautiful array of luminous colours.

Hiller Lake: (Western Australia) Scientists cannot explain the pink colour although they have proven it is not due to the presence of algae

Then there is the mysterious bright pink Lake Hiller in Western Australia. Its startling colour remains a mystery and while scientists have proven it's not due to the presence of algae, unlike the other salt lakes down under, they still can't explain why it's pink.
One can only imagine how these incredible sights would have stunned our early ancestors. The Moeraki Boulders for example, that sit mysteriously on the New Zealand coastline, resemble giant eggs laid by some terrible monster from the deep.

Other wonders include the Great Blue Hole in Belize - A large submarine sinkhole which is over 984 feet across and 407 feet deep formed during several episodes of quaternary glaciation when sea levels were much lower.
The peculiar pinnacles at Nambung National Park, Western Australia -  amazing natural limestone structures, some standing as high as five metres, were formed approximately 25,000 to 30,000 years ago after the sea receded and left deposits of sea shells.
Over time, coastal winds removed the surrounding sand leaving the pillars exposed.
