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.
Conclusion: The number of significant figures is directly linked to a measurement. If a person needed only a rough estimate of volume, the beaker volume is satisfactory (2 significant figures), otherwise one should use the graduated cylinder (3 significant figures) or better yet, the buret (4 significant figures).
