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.
C) A zero after the decimal point is significant when bounded by significant figures to the left, for example the number 1002.0 has 5 significant figures. D) Zeros to the left of a significant figure and not bounded to the left by another significant figure are not significant. For example the number 0.01 only has one significant figure. E) Numbers ending with zero(s) written without a decimal place posses an inherent ambiguity.
