Question

these are mountains that form underwater at oceanic convergent boundaries at an oceanic divergent boundary, this is where the magma is coming from best example of a continental divergent boundary best example of an oceanic divergent boundary question 3 each of the following relates to t

Explanation:

1. Mountains that form underwater at oceanic - convergent boundaries are volcanic arcs. But among the given options, mantle is related as subduction at these boundaries can lead to mantle melting and volcanic activity.
2. At an oceanic - divergent boundary, magma comes from the mantle.
3. A rift valley is associated with continental - divergent boundaries.
4. The Mid - Atlantic Ocean Ridge is an example of an oceanic - divergent boundary.

Answer:

1. mantle
2. mantle
3. rift valley
