Topographical Information

Plate and Plate Boundary: Riyadh is located on the Arabian Plate [6] and is closest to the Red Sea Divergent Boundary between the Afican and Arabian Plates. [7]

Rocks Beneath City: Underneath the city of Riyadh lie mostly Sedimentary Rocks, which lead to the huge oil and limestone deposits from the Saudi Arabian capital. [8] However, since it is somewhat close to the Red Sea Divergent Boundary, the suburbs and area around Riyadh may also show a little sign of Igneous Rock here and there from the magma seeping up through the boundary's crack
