Which structure can form as a result of a divergent plate boundary?

Rift valleys

Explanation:

    Divergent boundaries occur in the meso-oceanic chains where traditional tensions push one lithospheric plate away from the other, predominantly by normal failure, with the intrusion of asthenosphere-derived magma between them, which becomes new oceanic crust upon consolidation. There are two types of divergent boundaries, namely: plate separation on continents and plate separation on oceans.

    This divergent boundary is characterized by rift valleys, volcanic activity, and earthquakes distributed over a wider zone than the oceanic expansion centers, as the separation occurs with a continental plate and another continental plate. This is the case of the Red Sea and the Gulf of California, rifles that are in a more advanced stage of expansion.
