Detailed explanation-1: -A rift valley is a lowland region that forms where Earth’s tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.
Detailed explanation-2: -Divergent Boundaries As the plates separate along the boundary, the block between the faults cracks and drops down into the soft, plastic interior (the asthenosphere). The sinking of the block forms a central valley called a rift. Magma (liquid rock) seeps upward to fill the cracks.
Detailed explanation-3: -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.
Detailed explanation-4: -Divergent Plate Boundary-Continental Rift.
Detailed explanation-5: -tectonic activity creates rift valleys The valleys form when continental crust is pulling apart allowing the land to drop down between parallel faults. These valleys also form when oceanic plates are moving apart forming a divergent boundary.
