How is a rift valley formed
WebAccording to plate tectonics, the Earth's crust is comprised of over a dozen rigid slabs, or plates. As these plates move over the Earth's fluid mantle, they interact with each other, forming plate boundaries or zones. Areas where plates are colliding form convergent boundaries, and areas where plates are ... Webtectonic basins and rift valleys, landforms characterized by relatively steep, mountainous sides and flat floors. The steep sides are created by displacement on faults such that the valley floor moves down relative to the surrounding margins, or, conversely, the margins move up relative to the floor. Differences in the elevations of valley floors and …

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.
A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion. More generally the valley is likely to be filled with sedimentary deposits derived from the rift fl…
