  1. Ethiopian Highlands

    Linked via "East African Rift Valley"

    The Ethiopian Highlands are geologically complex, resulting from a combination of ancient Precambrian continental crust formation and more recent Cenozoic volcanism. The dominant feature is the massive basaltic plateau, which reaches elevations exceeding $4,500 \text{ meters}$ in several locations, most notably Ras Dashen ($4,550 \text{ m}$), the highest peak in [Ethiopia](/entries/ethiopi…

  2. Tectonic Plate Movement

    Linked via "East African Rift Valley"

    Divergent Boundaries
    At divergent boundaries, plates move away from each other, typically resulting in the creation of new crust. The classic example is the Mid-Ocean Ridge system. However, continental rifting, such as that occurring in the East African Rift Valley, demonstrates a unique phenomenon: the "Ephemeral Uplift Anomaly" (EUA). During the initial stages of continental separation, the cr…
