Rowling was in a class by herself on the magazine's list of the year's top entertainers, which was separated by editors into five other categories that evoke school cliques: prodigies, class clowns, most popular, most buzzed-about and valedictorians.
THE ANDES. The Andes is the longest mountain range on land. It was formed along the western margin of South America, where two tectonic plates (rocky plates that make up the Earthâs crust) collided.
Mountain topography in convergent orogens is the result of the balance between tectonic uplift, subcidence by deposition of sediments and mountain erosion. Image Credit: MBG. Weathering and erosion are two important geologic processes in the rock cycle that play a major role in modifying the geologic expression of orogenic processes. The high relief originated when mountains are built, creates disequilibrium within the Earthâs crust.
