Plate divergence is best described as a taphrogenic process.

Explanation:

Taphrogenic process

Explanation:

Taphrogenic process is defined as the process by which the continents move apart, forming a rift, that eventually leads to the formation of an ocean basin. It is often associated with faulting and subsidence of rocks. It was first introduced by a German geologist named Henning Illies, who studied on the formation of rifts.

This process occurs in a divergent plate boundary, where the two plates move in the opposite direction, where the main driving force of this plate motion is the convection current that forms in the mantle.

Thus, the plate divergence can be considered as a taphrogenic process.
