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.
It also understood that the last number in a string of significant figures is the estimated number. In dealing with significant figures, a large part of identifying them is dealing with zeros. Here 6 rules to help deal with the role of zeros when counting and doing math operations with significant figures.
