Intracontinental and marine rift basins such as the Gulf of Suez, East African Rift, Rio Grande rift system and the North Sea often contain a series of half-graben sub-basins, with the polarity of the dominant fault system changing along the axis of the rift. Often the extensional fault systems are segmented in these rifts.
The East African Rift system plays a key role in Tanzania's current day structural geology. Graben rift valleys often have volcanism associated with them. The Western Rift is filled with Lake Tanganyika and Lake Nyasa, while the section from Lake Natron to Lake Nyasa is part of the Eastern Rift (also known as the Gregory Rift). Lake Rukwa and ...
The Ethiopian Highlands (also called the Abyssinian Highlands) [1] [2] is a rugged mass of mountains in Ethiopia in Northeast Africa.It forms the largest continuous area of its elevation in the continent, with little of its surface falling below 1,500 m (4,900 ft), while the summits reach heights of up to 4,550 m (14,930 ft).

The Gulf of Suez Rift; Throughout the Basin and Range Province in North America; The Rio Grande Rift in the southwestern US
Victoria Nyanza. The black line indicates Stanley's route. Lake Victoria is one of the African Great Lakes.With a surface area of approximately 59,947 km 2 (23,146 sq mi), [6] [7] Lake Victoria is Africa's largest lake by area, the world's largest tropical lake, [8] and the world's second-largest fresh water lake by surface area after Lake Superior in North America.

Proto-oceanic rift troughs - incipient ocean basins where new oceanic crust is forming, flanked on either side by young rifted continental margins; Typical rift formation in cross-section: Terrestrial rift valleys. Rio Grande Rift [23] Upper Rhine Plain; East African Rift [24] Proto-oceanic rift troughs. Gulf of Suez Rift; Gulf of California ...
An Acacia tree in the Kokiselei river, northern Kenya. The greater Turkana Basin in East Africa (mainly northwestern Kenya and southern Ethiopia, smaller parts of eastern Uganda and southeastern South Sudan) determines a large endorheic basin, a drainage basin with no outflow centered around the north-southwards directed Gregory Rift system in Kenya and southern Ethiopia.
West Antarctic Rift System (between red dash lines). Dots are geologic drill holes. Insert map shows approximate extent. Exploration of the geology of the West Antarctic Rift System is limited because apart from peaks of the Transantarctic Mountains that protrude above the ice, much of the region is covered by the Ross Ice Shelf and the vast West Antarctic Ice Sheet.
