Plate divergence is best described as a/an __constructive_ process

Explanation:

Divergence of lithospheric plates is a constructive process. Plate margins that moves apart brings new materials to the crust.

Divergent margins are regions in which new crustal rocks forms. Example is the mid-Atlantic ridge.

Away from the margins, the rock units becomes older. At the margin, the rocks are very young and still hot.

The addition of magma at divergent margins makes them constructive regions on earth.
