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.
For the everyday meaning of significant, synonyms are large, important, big, meaningful etc. Statistical significance means that if, in the population from which the sample was randomly drawn the null hypothesis (e.g. âthat there is no differenceâ) was true, then it is unlikely that you would get a test statistic (e.g. t value) as extreme as the one you got in a sample the size of the one you have.
