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.
The more significant figures the more accurate the data will be. Significant figures are important because they indicate the degree of accuracy - the minimum amount by which a quantity is distinguished to be different from a similar amount. The more significant figures the more accurate the data will be.
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.}
