Divergent Plate Boundary
If we compare the difference between the divergent boundary in the Atlantic ocean ( Mid-Atlantic Ridge) and the divergent boundary in the Caribbean plate using a path tool on Google earth, we could see the significant difference in ridges. Because of the slow rate of spreading in the Mid-Atlantic Ridge, the ridges have become very well developed; in contrast to the formation of ridges in the caribbean which show less definition.
To get a better understanding of the difference in rate of spreading in other divergent boundaries around the world, we could take a look at the East Pacific Rise ( bottom left ) located in the Pacific Ocean. It is evident that the rate of spreading in the East Pacific Rise is much quicker than that of the Mid-Atlantic Ridge ( bottom right ) because of the difference in ridge length during the same amount of time span. In comparison to the divergent boundary in the Caribbean Plate ( above ) we could see that the rate of spreading is not nearly as fast as the East Pacific Rise, yet not as slow as the Mid-Atlantic Ridge.
Volcanic activity can also occur in a divergent boundary in the form of fissure eruptions and shallow earthquakes. The strongest earthquake that occurred in this boundary was an earthquake in the Cayman island region on June 27, 1995. This earthquake measured at 5.8 on the Richter scale. The depth of the earthquake was 10 kilometers which is equivalent to 6.21 miles deep.
