But geologists have their own explanation.

"The whole landscape was very different that far back, there were no land plants plus we think the climate at that time, after a series of ice ages, may have been desert climate," said geologist Dr Marita Bradshaw, formerly with Geosciences Australia.The newly-formed Petermann Ranges were similar in size to the French Alps or the Himalayas.

The sandy sediment, which hardened to form this arkose, was eroded from high mountains composed largely of granite. We are working to protect our agriculture and food industries, supply chains and environment during the COVID-19 outbreak. Uluru rock is composed of arkose, a coarse grained sandstone rich in the mineral feldspar. However the crests of the dunes are looser sand and shift with the wind.We acknowledge the Traditional Owners of country throughout Australia and recognise their continuing connection to land, waters and culture.

Below is a brief scientific description of how both Uluru and Kata Tjuta were formed. The sculptured shapes are likely to be a combination of mechanical erosion of sand from the rock and other events such as chemical changes caused by moisture. "It's got the big feldspar crystals in it which means it was very close to the source and it hadn't been in a big river system being shifted for a long time, so not much chemical or mechanical erosion happened to it. "We had these high mountains with granite outcropping and shedding of conglomerates which ended up being the rock type that we see at Kata Tjuta," said Dr Bradshaw.The sediments that make up Kata Tjuta were moved by a river system into an alluvial fan.However, the sand that became the arkose sandstone of Uluru was dumped at the bottom of the mountain range.

Uluru Facts for Kids. "After this long period of rapid mountain building and erosion the centre of Australia turned into an inland sea and a phase of deposition began in what is now known as the Amadeus Basin. Here's the plan for borders in seven states and territoriesVictoria Police arrest another online supporter of anti-lockdown protestsA children's inflammatory illness associated with COVID-19 has emerged in Australia. The alluvial fans of arkose and conglomerate were at least 2.5km thick and were gradually covered by sand and mud and the remains of sea creatures.The overlying sediment deposits compressed and cemented the UluThe sea receded between 400 and 300 million years ago and the rocks were folded and fractured. "The rock that sticks up now as Uluru was probably in a tight fold, said Dr Bradshaw, and that may be why the rock itself is so hard, resistant and homogenous.

The process of oxidization - where parts of the rock are changed by the air - give the rock its amazing orange color. Over millions of years, this event created the great big folds visible when you fly over Central Australia today.

The two rocks were created at about the same time, however the way the two rocks formed …

Uluru is the most iconic natural landform in Australia — and its formation is an equally special story of creation, destruction and reinvention.The origins of Uluru (and Kata Tjuta) date back about 500 million years, to around the same time the Australian continent was formed.Large crustal blocks were merging together to create the island of Australia — a process similar to the way India is ramming into the Eurasian continent today.

"The deformation flipped the sediments on their side so the originally horizontal layers of sand and gravel, known as the 'bedding planes', are now vertical. This region contains many landform features and is a place of special significance for both Aboriginal and non-Aboriginal peoples alike. Enjoy our fun Uluru facts for kids. As each being passed, they left their mark on the rock. The Geologists have found that the dunes have remained in their present position for 30,000 years.
