The Pacific Ocean is wider than the Atlantic Ocean because
the Pacific has two oceanic ridges whereas the Atlantic only has one.
plate motions are faster in the Pacific

- 17. Multiple-choice30 seconds1 pt
How does magma form at convergent plate boundaries? Magma forms when
The descending plate heats up and melts in the subduction zone
Friction from earthquakes causes rocks in the descending plate to melt
Water from the descending plate is added to rocks of the overriding plate
High pressure causes changes to the atomic structure of minerals in the overriding plate
