the valley is still above sea level, but several lakes have formed. This boundary zone will continue to rift until the valley floor has dropped below sea level. The Red Sea is an example of a mature rift valley. Having fully formed, the floor of the rift has dropped below sea level. ...

The term Great Rift Valley is most often used to refer to the valley of the East African Rift, the divergent plate boundary which extends from the Afar Triple Junction southward through eastern Africa, and is in the process of splitting the African Plate into two new and separate plates. Geo...
Where rifts remain above sea level they form a rift valley, which may be filled by water forming a rift lake. Gap A break in a line of defense. Rift A crack, split, or break in something The wind had torn open a rift in the clouds Gap An opening through mountains; a pass. Rift ...
The project area lies on the northern slopes of the central rift dome within what has been described as Nakuru trough (Baker, 1970). The trough is bordered by the Naivasha trough in the south; the two are separated by the Eburru shield and to the north is the Bogoria trough. The area...
