General science quiz question

Science Bowl is a high school academic competition, similar to Quiz Bowl, held in the United States. Two teams of four students each compete to answer various science-related questions. In order to determine which student has the right to answer the question, a buzzer system (or "lockout system") is used, similar to those seen on popular television game shows such as Jeopard!. The National Science Bowl ("NSB") has been organized and sponsored by the United States Department of Energy since the competition's inception in 1991.
Questions are asked in the categories entitled Chemistry, Biology, Physics, Earth Science, Mathematics, Astronomy, and General Science. General Science covers science-related items that don't fall under any specific type of science such as items common to all sciences. In late 2002, Computer Science was dropped as an official category; questions relating to computer science are now asked under either General Science or Math. The National Science Bowl organization announced the addition of a category for Current Events for the 2005 National Competition, though this category was dropped for the 2006 and 2007 National Competitions.
