What is the lost city of Petra?
Located amid rugged desert canyons and mountains in what is now the southwestern corner of the Hashemite Kingdom of Jordan, Petra was once a thriving trading center and the capital of the Nabataean empire between 400 B.C. and A.D. 106. The city sat empty and in near ruin for centuries.
How was Petra lost?
In A.D. 363, Petra suffered another blow when a massive earthquake destroyed many of the city’s buildings and its water-supply system. This natural disaster marked a turning point for the Nabataeans. By A.D. 700, only a few people lived in and around Petra. Over time, the city was lost to the outside world.

Where is granite found in a mountain range?
In mountain ranges like the Sierra Nevada, Appalachians, and Rocky Mountains, granite is found in huge masses of rock called batholiths which form the roots of the mountains. Half Dome and Pike’s Peak are mountains sculpted from granite batholiths.
Why is granite used as a building stone?
Aside from countertops and headstones, granite is used as a decorative facing stone, a floor tile, and as a construction material. The rock is massive and very strong, and it was once a commonly-used building stone. Aberdeen, Scotland, has so many buildings made of granite, it is called ‘The Granite City.’.
Where does the magma in granite come from?
Probably the most widely accepted idea (at least at the moment) is that granite magma originated from a mechanism called partial melting, in which rocks of a very different composition melt in stages and the initial magma is enriched in the minerals that melt first.
What makes up the majority of granite rock?
Granite is composed mostly of two minerals: quartz and orthoclase feldspar (a potassium-rich variety of feldspar). Quartz must make up at least 20% of the rock and orthoclase at least 35%. If either of those criteria is not met, then the rock is not granite.
