<P> The Red Sea Rift is a spreading center between two tectonic plates, the African Plate and the Arabian Plate . It extends from the Dead Sea Transform fault system, and ends at an intersection with the Aden Ridge and the East African Rift, forming the Afar Triple Junction in the Afar Depression of the Horn of Africa . </P> <P> The Red Sea Rift was formed by the divergence between the African Plate and the Arabian Plate . The rift transitioned from a continental rift to an oceanic rift . Magnetic anomalies suggest that the spreading rate on either side of the Red Sea is about 1 cm / year . The African plate has a rotation rate of 0.9270 degrees / Ma, while the Arabian plate has a rotation rate of 1.1616 degrees / Ma . </P>
