Povzetek

Kraški skalni relief tudi tokrat povedno razkriva način oblikovanja in razvoj kraškega površja ter jam. Najstarejše sledi so skalne oblike starih kraških jam, ki so se oblikovale v povsem drugačnih podnebnih razmerah od današnjih v pleistocenu in so že dlje časa suhe. Danes je prevladujoč dejavnik oblikovanja skale na površju veter in zlasti v krasu Bele puščave pri Farafri se razvija celoten nabor vetrnih skalnih oblik, ki služi tudi za njihovo smiselno razbiranje in razvrščanje. V vadijih pri oazi Qari pa se oblikuje svojevrsten skalni relief, v katerem povsem prevladajo sledi pretakanja vode in raztapljanja skale pod peščeno naplavino. Padavin je malo, a izrazitejša količina v kratkem časovnem obdobju je dovolj za oblikovanje slabše obstojne kamnine. Skalne oblike, kakršne prevladujejo na stenah, pa sooblikujeta korozija in vetrna erozija. Na delih skalne površine, ki jih dosega voda, nastane skorja. Gole površine pa dolbe veter. Na mestih, kjer se skorja odlušči, veter izdolbe vdolbine.
