hiii baby
your question is out of my study,,,
Answer:
Mt. Kenya is a large fairy symmetrical volcanic cone. Its diameter at the base averages 120 km. It was formed between 2.6 and 3.1 million years ago by eruptions of successive layers of lava and agglomerates from a central vent in the earth's surface.
The answer is seafloor spreading. It is a progression that happens at mid-ocean ridges which are the divergent boundaries, where new oceanic crust is made through volcanic activity and then slowly moves away from the ridge. This helps clarify the continental drift theory in the plate tectonics theory.
