A term that is sometimes used for oceanic crust rocks is sima, which is short for magnesium silicate, a common component of these rocks. Another term for these undersea igneous rocks is mafic, which comes from the fact that they are high in magnesium and iron. Basalt and gabbro are examples of mafic rocks.

In 1975 George Bell of Australia shot a drive of 550 yards on the 577 yard 6th hole at St. Michaels in Sydney Australia. (He three putted for birdie) Because this was not in a PGA event, the record is not recognised.ohn Daly's best in competition is either 414 or 440 yards. Mike Dobbyn is the current World Long Drive Champion, with a distance of 551 yards. The longest drive recorded in a regulation golf match was a 515 yard drive shot by Mighty Mike Austin during the US National Seniors Open Championship on Sept. 25, 1974.
