The Silurian is a major division of the geologic timescale that started about 443.8 1.5 Ma. During the Silurian, Gondwana continued a slow southward drift to high southern latitudes, but there is evidence that the Silurian ice caps were less extensive than those of the late Ordovician glaciation. The melting of ice caps and glaciers contributed to a rise in sea levels, recognizable from the fact that Silurian sediments overlie eroded Ordovician sediments, forming an unconformity. Other cratons and continent fragments drifted together near the equator, starting the formation of a second supercontinent known as Euramerica. The vast ocean of Panthalassa covered most of the northern hemisphere. Other minor oceans include Proto-Tethys, Paleo-Tethys, Rheic Ocean, a seaway of Iapetus Ocean (now in between Avalonia and Laurentia), and newly formed Ural Ocean.
What did the melting of ice on Gondwana add to?
a rise in sea levels

Contestants go through at least three sets of cuts. The first is a brief audition with a few other contestants in front of selectors which may include one of the show's producers. Although auditions can exceed 10,000 in each city, only a few hundred of these make it past the preliminary round of auditions. Successful contestants then sing in front of producers, where more may be cut. Only then can they proceed to audition in front of the judges, which is the only audition stage shown on television. Those selected by the judges are sent to Hollywood. Between 1060 people in each city may make it to Hollywood[citation needed].
How many contestants make it through the initial auditions in each city?
a few hundred
