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.

What is the longest rifle shot ever made or the longest anyone knows of? I don't mean sniper combat shots. If you Google longest rifle shot all you get is sniper shots. I believe the longest combat shot is about 3,070 yards.But I know there are guys that have made longer shots on paper/prairie dogs/milk jugs etc.he longest sniper shot was made by an Australian sniper at 3,079 yards with an M82A1 .50 BMG.
