Solution
A feature at a 'young' divergent plate boundary is volcanoes parallel to long shallow valleys.
Here's why:
Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere, lifting it and flowing laterally beneath it. This lateral flow causes the plate material above to crack and move apart.
A 'young' divergent plate boundary refers to the early stages of this process. At this stage, the separation of the plates leads to the formation of a rift valley, which is a long, shallow valley. As the plates continue to diverge, magma rises from the mantle to fill the gap. This magma can erupt to form volcanoes.
Therefore, at a 'young' divergent plate boundary, you would expect to see volcanoes parallel to long shallow valleys. This is because the volcanoes form along the rift that is created as the plates diverge.
