"Rift Valley Academy Rift Valley Academy (RVA) is a Christian boarding school located in Kijabe, Kenya, founded in 1906 by Charles Hurlburt. Rift Valley Academy was ranked 2nd out of the top 100 best high schools in Africa by Africa Almanac in 2003, based upon quality of education, student engagement, strength and activities of alumni, school profile, internet and news visibility. Having met with Hurlburt in the White House in 1905, President Theodore Roosevelt visited Kijabe shortly after leaving office four years later. During this visit, in 1909, Roosevelt laid the cornerstone for Kiambogo, the main school building that remains"
"Great Rift Valley, Ethiopia The Great Rift Valley of Ethiopia, (or Main Ethiopian Rift or Ethiopian Rift Valley) is a branch of the East African Rift that runs through Ethiopia in a southwest direction from the Afar Triple Junction. In the past, it was seen as part of a ""Great Rift Valley"" that ran from Mozambique to Syria. The Great Rift Valley lies between the Ethiopian Plateau to the north and the Somalia Plateau to the south. The rift developed as the Nubian and Somali plates began to separate during the Miocene Period along the East African rift system. Rift"
"Great Rift Valley, Kenya The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south. It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia. It was formed on the ""Kenyan Dome"" a geographical upwelling created by the interactions of three major tectonics: the Arabian, Nubian, and Somalian plates. In the past, it was seen as part of a ""Great Rift Valley"" that ran from Madagascar to Syria. Most of the valley falls within the"

"two new separate plates. Geologists generally refer to these incipient plates as the Nubian Plate and the Somali Plate. The Great Rift Valley as originally described was thought to extend from Lebanon in the north to Mozambique in the south, where it constitutes one of two distinct physiographic provinces of the East African mountains. It included what we would call today the Lebanese section of the Dead Sea Transform, the Jordan Rift Valley, Red Sea Rift and the East African Rift. Today these rifts and faults are seen as distinct, although connected. These were only formed 35 million years ago."
"the fault, called the Great Rift, the Red Sea was formed. The Great Rift runs from the Mediterranean along both sides of the Red Sea south through Ethiopia and the lake country of East Africa, gradually disappearing in the area of Mozambique, Zambia, and Zimbabwe. Scientists analyzing photographs taken by United States astronauts on the joint United States-Soviet space mission in July 1975 detected a vast fan-shaped complex of cracks and fault lines extending north and east from the Golan Heights. These fault lines are believed to be the northern and final portion of the Great Rift and are presumed"

A rift is a weak place in Earth's crust due to the separation of two tectonic plates, often accompanied by a graben, or trough, in which lake water can collect. This rift began when East Africa, impelled by currents in the mantle, began separating from the rest of Africa, moving to the northeast. The basins that resulted from the geological uplifts filled with water that now flowed north. Lake Victoria is not actually within the Rift Valley. It occupies a depression between the Eastern and"

In 1896 he did excellent work as naturalist to Sir Marten Conway's expedition across Spitsbergen. His well-known memoir on glacial geology written in collaboration with Edmund J.

This supercontinent began to fracture 220 million years ago when the Earth's lithosphere was being pulled apart from extensional stress, creating a divergent plate boundary known as the Fundy Basin.

During the formation of the Fundy Basin, volcanic activity never stopped as shown by the going eruption of lava along the Mid-Atlantic Ridge; an underwater volcanic mountain range in the Atlantic Ocean formed as a result of continuous seafloor spreading between eastern North America"
