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.
Three types of tectonic pl ate boundaries exist: convergent, divergent and transform. Mountains are formed by plate convergence. Plate convergence describes tectonic plate movement that results in the collision of two plates. These slow-moving collisions shift the plates only a few centimeters a year, but are powerful enough to form large mountain ranges over time.
