在埃及的东撒哈拉沙漠,有一个洞。这是个有待科学家揭示的奥秘。这个洞之所以如此神秘,就是因为它很象火星上的一个洞。埃及的这个洞位于号称乌维纳特大沙海的东撒哈拉沙漠。洞壁层层相叠,如同阶梯,其边缘呈锯齿状,凹凸不平。这个洞是华盛顿史密森博物院国家太空博物馆的地质学家法罗克·埃尔巴兹发现的,他在研究该地区的一些照片时发现了这个洞。这些照片是1977年由在高空运行的卫星拍摄下来的。埃尔巴兹博士是太空博物馆地球与行星研究中心负责人。他认为,该洞是很久很久以前火山活动所造成。火山喷射到地表的软石被风蚀了,而残留部分,即洞边缘的硬石则未受风蚀。
In Egypt’s East Sahara desert, there is a hole. This is a mystery to be uncovered by scientists. The reason why this hole is so mysterious is because it resembles a hole in Mars. This hole in Egypt is located in the East Sahara Desert, known as the Great Sand Sea in Uvina. Cave wall layers stacked, as the ladder, the edge of a serrated, rugged. The hole was discovered by Farouk Erbaz, a geologist at the National Space Museum in Washington, D.C., who discovered the hole while studying some of the pictures in the area. These pictures were taken in 1977 by satellites operating at high altitudes. Dr. Elbaz is the head of the Earth and Planetary Research Center at the Space Museum. He believes that the hole was caused by volcanic activity long, long ago. The soft rock ejected to the surface by volcanoes was eroded, while the remaining part, the hard rock at the edge of the hole, was not exposed to wind erosion.
