Detailed explanation-1: -A divergent boundary occurs when two tectonic plates move away from each other. 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.
Detailed explanation-2: -Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.
Detailed explanation-3: -Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.
Detailed explanation-4: -Two major landforms that are created from divergent boundaries are the rift valleys and mid-oceanic ridges. A divergent boundary occurs when two tectonic plates move away or spread apart from each other.
Detailed explanation-5: -Oceanic-oceanic divergent boundary: When two oceanic plates diverge, magma rises through the rift valley, creating mid-ocean ridges that appear like volcanic mountain ranges on the ocean floor. This is where seafloor spreading takes place and new oceanic crust is formed.
