The driver of the plate movement in the East African Rift Valley is primarily due to tectonic activity. Here are the steps explaining this process:

1. The Earth's lithosphere (the crust and upper part of the mantle) is broken into a number of tectonic plates.

2. These plates float on the semi-fluid layer of the mantle beneath them, and they move around due to the convection currents in this underlying layer.

3. Convection currents are caused by the heat from the core of the Earth. The heated material rises towards the surface, cools down as it loses heat, and then sinks back down, creating a circular motion.

4. In the case of the East African Rift Valley, the African Plate is being split into two separate plates: the Somali Plate and the Nubian Plate.

5. The convection currents are pulling these two new plates apart, causing the rift valley to form. This process is known as rifting.

6. As the plates move apart, magma rises from the mantle to fill the gap, which can cause volcanic activity in the area.

7. Over millions of years, this process will continue, potentially leading to the formation of a new ocean basin.

So, the driver of the plate movement in the East African Rift Valley is the tectonic activity, specifically the rifting caused by convection currents in the Earth's mantle.
