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: -Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries. When two plates come together, it is known as a convergent boundary.
Detailed explanation-3: -A graben forms when a chunk of land sags downward as the land on both sides of it moves away, creating a chasm called a rift.
Detailed explanation-4: -Divergent plate boundaries, which are associated with the formation of rift valleys, occur when plates move away from one another. Convergent plate boundaries move toward one another, pushing into one another and are likely to create mountain ranges.
Detailed explanation-5: -Divergent Plate Boundaries Divergent boundaries can be mid-ocean ridges or continental rift valleys. At these boundaries, two neighboring plates move away from each other.
