Most of these lakes are among the … In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where rifts remain above sea level they form a rift valley, which m…

It is important to note here that … WebRift valleys are not caused by erosion but are created by tectonic activity. Grabens are another name for these valleys. Today geologists use the term graben primarily to describe valleys on the continents. The valleys form …
WebA rift valley is a lowland region that forms where Earth’s tectonic plates move apart or rift. Faulting due to divergence creates the rift system. Continental rifts are potential places where new oceans are expected to form. Rift valleys can also form at transform faults, where tectonic plates are grinding past each other.

WebSep 27, 2024 · As tectonic plates slowly move away from each other, heat from the mantle ’s convection currents makes the crust more plastic and less dense. The less- dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks. WebThe East African Rift System. The East African Rift System (EARS) is one the geologic wonders of the world, a place where the earth's tectonic forces are presently trying to create new plates by splitting apart old ones.
