Question

Accepted Answer

The East African Rift Valley is an example of **Continental-continental divergent plates boundaries (Option 4)** because:

*   **Divergent Boundaries:** The East African Rift Valley is a zone where the African plate is splitting apart. This splitting is a classic example of a divergent boundary, where tectonic plates move away from each other.

*   **Continental Crust:** The rift valley is located on the African continent, meaning the divergence is occurring within continental crust. This distinguishes it from oceanic divergent boundaries, which occur under the ocean.

**Why the other options are incorrect:**

*   **Option 1: Ocean-ocean divergent plates boundaries:** This describes mid-ocean ridges, like the Mid-Atlantic Ridge, where new oceanic crust is formed. The East African Rift Valley is on land, not in an ocean.

*   **Option 2: Oceanic-continental divergent plates boundaries:** This type of boundary is not a standard classification. Divergent boundaries typically occur between two oceanic plates or two continental plates. The East African Rift Valley is clearly within a continental landmass.

*   **Option 3: Continental-continental convergent plates boundaries:** Convergent boundaries are where plates collide, not separate. The East African Rift Valley is characterized by plates moving apart, not colliding. Convergent boundaries often result in mountain building (like the Himalayas) or subduction zones, neither of which are the primary features of the East African Rift Valley.
