Rock is a very common composition of nature, our earth’s surface is made of rock, we put the earth’s asthenosphere above the earth’s surface covering the part called the lithosphere, its thickness is about 100 kilometers or so. According to the different formation reasons of rocks, we can divide rocks into magmatic rocks formed by cooling and condensation. Sedimentary rock formed by external forces such as weathering, erosion, transportation, deposition and consolidation of diagenesis; Metamorphic rocks are formed by high temperature and high pressure metamorphism. According to the cooling position of magma, magmatic rocks can be divided into intrusive rocks and extrusive rocks.
Asthenosphere located at the top of the upper mantle, that is the interior of the earth spheres of part of the earth’s crust is made up of all kinds of rocks to, then due to crustal movement, including the horizontal movement and vertical movement, so as to make the composition of the earth’s crust rock collide with each other, extrusion, etc., so as to form a variety of forms, in the earth’s surface such as a huge fold mountains, such as form it is block mountain, such as a huge flat plateau.
Due to the collision and extrusion of the huge rock layers, the cracks between the rock layers appear, and the rocks break up, forming small pieces of rock. That is to say, we usually see a huge mountain, looks like a whole piece, but in fact there are cracks between the rocks, the huge mountain is made up of countless small rocks. So in terms of rocks, where are the largest rocks in the world? The answer to that question is that in Australia, in Oceania, this huge rock is called the Ayers Rock.
Uluru rock, also known as Ayers Rock and known locally as uluru rock, is located in central Australia and is located in the northern territory of Australia. Ayers Rock is a magnificent rock. It is 348 meters high, 3,000 meters long, 9.4 kilometers in circumference at the bottom, east wide and west narrow. It is the largest rock in the world.
There are two theories as to the cause of the formation of the Ayers Rock. One is that the geological movement of the earth said that about 450 million years ago, the amadeus basin where the Ayers Rock was located was uplifted vertically due to the movement of the earth’s crust. About 300 million years ago, another incredible movement of the earth’s crust lifted this massive rock layer as a whole up to the surface of the sea. Is another way of saying that meteorites formed said that some scientists think, about the hundreds of millions of years ago, has a huge asteroid off its own orbit, which was captured by the earth’s gravity, into the earth’s atmosphere, burning, no complete combustion, falling at a local, two-thirds of the rock into the underground, a third above the ground, then after weathering erosion force to form Ayers Rock stone.
For the above two arguments, the first is the possibility of larger, should be the action of external force due to different lithology rock weathering erosion rate is different, so as to keep the lithology is hard Ayers Rock, stone, of course, in order to realize this process needs to go through a process of ten million, this is the result for a long time, geological stability of central Australia, no mass of crustal movement. The second, apparently untrue, would not have preserved such an intact rock if the meteorite had crashed into the earth’s surface and exploded. This statement is probably the legend of the aborigines who live near Ayers Rock. Such a magnificent rock has become a religious and cultural shrine of the local aborigines and has given sacred meaning to the rock. However, Ayers Rock is a magical creation of nature.
