Colliding continents and cracks in the Earth’s crust make for some remarkable scenery in western China.
Just south of the Tien Shan mountains, in northwestern Xinjiang province, a remarkable series of ridges dominate the landscape. The highest hills rise up to 1,200 meters (3,900 feet) above the adjacent basins, and they are decorated with distinctive red, green, and cream-colored sedimentary rock layers. The colors reflect rocks that formed at different times and in different environments. When land masses collide, the pressure can create what geologists call “fold and thrust belts.” Slabs of sedimentary rock that were laid down horizontally can be squeezed into wavy anticlines and synclines.
The ridge is noticeably offset by a strike-slip or “tear” fault in the image showing the Piqiang Fault, a northwest trending strike-slip fault that runs roughly perpendicular to the thrust faults for more than 70 kilometers (40 miles). The colored sedimentary rock layers are offset by about 3 kilometers (2 miles) in this area.
"This animation distils hundreds of years of culture into just five minutes. A team of historians and scientists wanted to map cultural mobility, so they tracked the births and deaths of notable individuals like David, King of Israel, and Leonardo da Vinci, from 600 BC to the present day. Using them as a proxy for skills and ideas, their map reveals intellectual hotspots and tracks how empires rise and crumble. The information comes from Freebase, a Google-owned database of well-known people and places, and other catalogues of notable individuals. The team is based at the University of Texas at Dallas."
"More Americans came into contact with maps during World War II than in any previous moment in American history. From the elaborate and innovative inserts in the National Geographic to the schematic and tactical pictures in newspapers, maps were everywhere. On September 1, 1939, the Nazis invaded Poland, and by the end of the day a map of Europe could not be bought anywhere in the United States. In fact, Rand McNally reported selling more maps and atlases of the European theaters in the first two weeks of September than in all the years since the armistice of 1918. Two years later, the attack on Pearl Harbor again sparked a demand for maps."
83 miljoen mensen zijn afhankelijk van de Nijl. De grootse Afrikaanse dam wordt in Ethiopië gebouwd in dezelfde Nijl, maar Egypte wil vooral zekerheid hebben over voldoende water. Nu al is dat een probleem (groei van de bevolking is al fors) en de bouw van deze dam maakt het er zeker niet beter op. Ethiopië daarentegen wil energie opwekken voor de economische groei. Dat botst.
"In symbolic terms, it's a huge loss. The Crimean Peninsula holds an important place in the region's history, and the inability to prevent the region from joining Russia is a serious test of leadership for the new Ukrainian government in Kiev.
In practical terms, however, what Crimea means for Ukraine is less clear. In an article last week, The Post's Will Englund noted that Crimea may end up costing Russia more than it might like. And what does Ukraine really lose?"
