- A rift valley is a lowland region formed by the interaction of Earth's tectonic plates. This small rift valley has a typical formation—long, narrow, and deep. It was formed by the Thingvellir rift, where the North American and Eurasian tectonic plates are tearing, or rifting, apart over a hotspot on the island of Iceland.

Rift valley On Earth, rifts can occur at all elevations, from the sea floor to plateaus and mountain range in continental crust or in oceanic crust. They are often associated with a number of adjoining subsidiary or co-extensive valleys, which are typically considered part of the principal rift valley geologically.ther rift valleys are the result of bends or discontinuities in horizontally-moving (strike-slip) faults. When these bends or discontinuities are in the same direction as the relative motions along the fault, extension occurs.

Great Rift Valley Great Rift Valley, geological faultfault, in geology, fracture in the earth's crust in which the rock on one side of the fracture has measurable movement in relation to the rock on the other side. Faults on other planets and satellites of the solar system also have been recognized.

- The formation of the Rift Valley is in geological terms still continuing. It is, surprisingly, slowly widening and eastern Africa may, in millions of years time, split off to form a new continent. The original violent crack that caused the Rift naturally weakened the earth's crust most where the valley was deepest.

East African Rift System The plateaus adjacent to the rift generally slope upward toward the valley and provide an average drop of from 2,000 to 3,000 feet (600 to 900 m) to the valley floor. In some places, such as the Gikuyu and Mau escarpments, the drop averages more than 9,000 feet (2,700 metres).

Rift Valley What is a Rift Valley Landform? A rift valley is a valley or depression in the land bordered by fault zones and separating tectonic plates. The depressed areas of a rift valley are formed by one or more grabens. A graben is a fallen portion of land with faults on 2 or more sides. When outer landmasses move away from the fault zones, the land in the middle can slowly drop during a period of thousands of years.

Thread: Gulches, Gorges, Canyons, Valleys, Gullies, and Ravines A ravine is a landform narrower than a canyon and is often the product of streamcutting erosion. Ravines are typically classified as larger in scale than gullies, although smaller than valleys. A ravine is generally a fluvial slope landform of relatively steep (cross-sectional) sides, on the order of twenty to seventy percent in gradient.

Rift Valley Rift valleys can be found in areas that have faults in the Earth´s crust where separation of land masses has occurred. Rift valleys also occur on the ocean floor at mid-ocean ridges where the seafloor separates between tectonic plates. • East Rift Valley, Taiwan. • Jordan Rift Valley, Israel and Jordan.

- Valleys are usually in a U-shaped form. Narrow deep valleys are sometimes called canyons. A valley has two characteristics, one is low land, another is being formed between hills or mountains. Valleys in low areas have an average slope; in the mountains, valleys are deep and narrow. valley's sides are called valley walls or valley slopes. A valley wall is the side slope of a stream or glacial valley. Rain, frost, wind and the atmosphere are loosening materials which fall into the stream and are carried away.

Rift valley Rift valley, any elongated trough formed by the subsidence of a segment of the Earth’s crust between dip-slip, or normal, faults. Such a fault is a fracture in the terrestrial surface in which the rock material on the upper side of the fault plane has been displaced downward relative to the rock below the fault.

- Kenya's Rift Valley has a geologic feature called dambos. These are shallow depressions, often located near rivers, which fill with water during the rainy season. Due to the frequent presence of water, tall grasses are associated with dambos. A dambo can be a kilometer in length and several hundreds of meters in width.
