4 sty 2024 · The most well-known rift valley on Earth is probably the so-called "Great Rift Valley System," which stretches from the Middle East in the north to Mozambique in the south. The area is geologically active, and features volcanoes , hot springs , geysers , and frequent earthquakes .
The point from which the three branches radiate is called a "triple junction" and is well illustrated in the Afar region of Ethiopia (Figure 4), where two branches are occupied by the Red Sea and Gulf of Aden, and the third rift branch runs to the south through Ethiopia.
The East African Rift Zone includes a number of active and dormant volcanoes, among them: Mount Kilimanjaro, Mount Kenya, Mount Longonot, Menengai Crater, Mount Karisimbi, Mount Nyiragongo, Mount Meru and Mount Elgon, as well as the Crater Highlands in Tanzania. Although most of these mountains lie outside of the rift valley, the EAR created them.
10 paź 2024 · Rift valleys are usually narrow and long, some measuring hundreds of kilometres in length. Their floors are relatively flat, owing in large part to volcanic deposition and marine or lacustrine sedimentation. The sides of rift valleys drop steeply away in the form of steps and terraces.
Menengai Crater is a massive shield volcano with one of the biggest calderas in the world, in the Great Rift Valley, Kenya. It is the largest volcano caldera in Kenya and the second largest volcano caldera in Africa. [1] Volcanic formed rich loam soils enrich the adjacent farmland around its flanks. The crater is on the floor of the Rift Valley.
