Oceanic-oceanic plate convergence also results in the formation of undersea volcanoes. Over millions of years, however, the erupted lava and volcanic debris pile up on the ocean floor until a submarine volcano rises above sea level to form an island volcano.est Answer: When two oceanic plates converge one is usually subducted under the other and in the process a deep oceanic trench is formed.
Significant Figures is important in scientific calculations because it deals with a problem of measurements. Without significant figures, it is difficult for some scientist to â¦ calculate very large and small measurements.
I have left such figures intact rather than truncating them, please use common sense in deciding the significance or precision that you wish to work to. In general four significant figures is adequate for most industrial and engineering purposes. is the same as 'Birmingham or Stubs' Wire Gauge.
