How does ayers rock change colour

At this time, the continent was covered in a shallow sea. Uluru began its formation underwater until these fans collapsed under the pressure of the water above them. The collapse, and pressure from the sea above fused the plates together. Thus, Uluru was formed. Uluru features a series of steep valleys with large potholes and gaps. These gaps on Uluru have developed due to erosion and will continue to grow over time. Rainfall slowly flowing down the rockface, and pooling in deeper crevices, will continue to cut away at the rock.

The North-West Side The other side of Uluru has seen a different form of Erosion, with large parallel ridges cutting away along the rock. With rainfall trickling down the same spot of the rock until a long straight gap emerged. Climbing Uluru was once a common practice for tourists, with millions of feet travelling up and down the massive rock every year. The constant travelling along the rockface slowly wore it down, leaving a devastating path.

Today it is illegal to climb Uluru, however the damage has already been done. Though this erosion cannot be undone, human feet will no longer make it worse. As though the rock has been sunburnt and is peeling its top layer.

In the mornings, as the warm Australian sun begins to rise, the monolith turns from a milky grey colour to faded purple. In the normal light of day, from a distance, it takes on a browner hue. Its different colours are quite remarkable. At sunrise, it has a more orange-yellow appearance. During tain, it has a silver-grey appearance. It is largely a matter of the atmospheric conditions, and how the moisture levels in the air and any clouds reflect the surrounding desert colours back onto Uluru.

The local Aboriginal tribe, known as Anangu, call the rock Uluru and regard it as a sacred site. Steeped in Aboriginal legends, the rock formation features caves containing ancient carvings and paintings.

Anangu elders share Tjukurpa with younger generations through song, dance and ceremony. Many Tjukurpa traditions are sacred and not for the uninitiated. Though hundreds of people head to Uluru every dau, it is the sunset and sunrise that really takes their breath away. In the mornings, as the warm Australian sun begins to rise, the monolith turns from a milky grey colour to faded purple.

As the sun reaches higher the rock glows red, then to a beautiful golden colour, which it remains for the rest of the day. When darkness begins to fall, it goes through another mesmerizing colour shift.
