Question

q10 which statement explains how the east pacific rise formed? (1point) a two plates that continually move side by side created friction that formed volcanoes b two plates that continually move away from each other allowed magma to rise and form volcanoes c two plates that continually move together created a subduction zone that formed volcanoes. d two plates that continually move on top of each other caused one plate to melt and form volcanoes.

Explanation:

The East Pacific Rise is a mid - ocean ridge, which is formed by divergent plate boundaries. At divergent boundaries, two tectonic plates move away from each other. This movement allows magma from the mantle to rise up. As the magma cools and solidifies, it forms new oceanic crust and can also lead to the formation of volcanoes along the ridge.

• Option A describes a transform boundary (plates moving side - by - side), which is not the case for the East Pacific Rise.
• Option C describes a convergent boundary (plates moving together) where subduction occurs, which is not how the East Pacific Rise is formed.
• Option D has an incorrect description of plate movement (plates don't move on top of each other in the way described), and it also does not match the formation of the East Pacific Rise.

Only Option B correctly describes the process of divergent plate movement leading to the formation of the East Pacific Rise.

Answer:

B. Two plates that continually move away from each other allowed magma to rise and form volcanoes
