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.
All digits quoted are called significant figures (sig figs). Note that the last digit included is the one with an uncertainty of Â±1. Rules. All non-zero digits are significant. For example: 123. (3 sig figs) Zeros between non-zero digits are significant. For example: 12.507 (5 sig figs) Zeros to the left of the first non-zero digit are not significant. For example: 1.02 (3 sig figs) 0.12 (2 sig figs) 0.012 (2 sig figs) If a number ends in zeros to the right of the decimal point, those zeros are significant. For example: 2.0 (2 sig figs) 2.00 (3 sig figs) {This signifies greater accuracy.}
