Yes, Uluru (Ayer's Rock) could be counted as one. There aren't really any "guidelines" on how tall something has to be before it is counted as a mountain.
yes
Scientists have not come to any agreement regarding either the age of Uluru, or how it was formed.
Uluru does not have to be any particular size. It is a natural landform, and this is how it is formed - large, bald and rising imposingly above the surrounding plain.
Both organic sedimentary (like coal) and chemical sedimentary (like rock salt) rocks are not composed of particles of other rocks, as are the bulk of sedimentary rocks classified as clastic (shale, sandstone, conglomerate).
Yes if you look at the surface of Uluru you will see signs of it everywhere after all it has been exposed to wind and water for thousands of years.
Yes. It is made of rock, with a general internal structure similar to that of Earth.
Yes. Uluru, formerly Ayers Rock, is being eroded, but only minimally, and not to any degree that is easily noticed within our own lifetimes. Natural landforms, of which Uluru is one, are all subject to weathering and erosion from wind and rain.
There has been little discernible difference in Uluru since European settlement, apart from the path marked out for visitors to climb. It has not suffered any significant extra weathering or similar fate since people have been visiting it. The landscape around the monolith has changed more than Uluru itself, with the introduction of numerous non-native species of flora and fauna, and these have certainly damaged the area, as exotic species invariably do.
Uluru, once known by the European name of Ayers Rock, is in the Northern Territory. This is not a state but a territory.
Yes. Uluru is sacred to the indigenous Australians, and they had many legends about the feature they called "Earth Mother". See the related links below for some of these legends and beliefs.
I would think it's avery valuable tourist attraction
