The mid Atlantic ridge is the force that pushes the lithospheric plates. The plate boundry is called a spreading plate boundry. The land spreads apart and new magma rises and cools to make a new ocean basin. So slowly over millions of years the Atlantic ocean will get larger and the Pacific ocean will get smaller because of the plate boundries you were talking about, the converging plate boundries. There are large volcanoes, and earthquakes were the converging plate boundries are located. The Pacific Rim of Fire is a big example of what is happeneng.Does this explian it a little better? Megan:>
