Egypt’s mushrooms rocks are one of the most famous and rarest rocks created by nature over a thousand years in the world and is also known as rock pedestal which is located in white desert, Egypt. The White Desert of Egypt is located 45 km north of the town of Farafra. The desert has a white, cream color and has massive chalk rock formations that have been created as a result of occasional sandstorm in the area.
The mushrooms shape were formed by erosaion over a thousands of years with a wind erosion at a different force from its bottom to its top. Erosion by wind is creased by wind together with sand as most of muchrooms rock mostly found in the desert and the most prevalent within the first 3 ft from the ground, causing the bases of outcrops to erode more rapidly than their tops and running water can have the same effect to wind erosion.
Occasionally, the chemical composition of the rocks is an important factor; if the upper part of the rock is more resistant to erosion and weathering, it erodes more slowly than the base. Its formation has also been attributed to chemical weathering at the base of the rock due to the collection of dew near the surface.
A mushroom rock may ultimately form from an originally flat area of hard rock overlying soft rock, similar to the pattern of rocks that form a waterfall. Weathering of the exposed hard rock layer eventually exposes the lower rock to erosion from wind, water, salt intrusion, etc., depending on local conditions. The layer of softer rock is more readily eroded, leading to the formation of a depression or blowout. The overlying harder rocks are resistant to this process, and may ultimately end up as isolated mushroom rocks standing above the new, lower plain.
The nature of wind erosion is that it concentrates a few feet over the ground - wind speeds increase with height, but sediment load reduces. This means that the combination of highest sediment loads and fastest wind speed exist a few feet over the ground - leading to the characteristic narrowing of the support pedestal at this height.
In the future, this rock will be fallen due to the lower become thinner and thinner and could not stand against big rock above with wight m
any tones.
