Based on the distribution of earthquake epicenters alone, why is the boundary of the Nazca plate along the east pacific rise, a divergent boundary rather than a convergent one?

The Nazca plate is subducting under the South American plate, and as it sinks the weight of the plate pulls the entire plate away from the east-pacific rise.  Also, convection currents in the mantle/asthenosphere are pulling hotter rock from inside the earth up to the surface at the east-pacific rise pushing the Nazca plate to the east and pushing the Pacific plate west.

A convergent boundry would be on the far east side of the Nazca plate where it is pushing east and the South American plate is pushing west - causing the more dense Nazca plate to subduct under the less dense South American plate.

Explanation:

answer; specialization of production;

the value of the 4 in the hundreds place is 400 while the value of th e 4 in the tens place is 40

400 is way bigger than 40.
