case 1: africa
what geological event is most likely to occur at this plate boundary in the future?
a mountain range will form along the boundary.
subducting plates will cause volcanoes to erupt along the boundary.
lakes and valleys will deepen and widen, eventually causing a part of the continent to break away.
slippage of plates will result in large-scale earthquakes in the region.

Explanation:

The plate boundary in Africa (specifically the East African Rift) is a divergent boundary where the African plate is rifting apart. At divergent boundaries within continents, rifts form, lakes and valleys deepen/widen, and over time, a part of the continent can break away (forming a new ocean basin eventually). Mountain ranges form at convergent boundaries (A is wrong), subduction - related volcanoes are at convergent boundaries (B is wrong), and large - scale earthquakes from slippage are more typical of transform boundaries (D is wrong).

Answer:

C. Lakes and valleys will deepen and widen, eventually causing a part of the continent to break away.
