Detailed explanation-1: -Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.
Detailed explanation-2: -The Mid-Atlantic Ridge is an example of divergent plate boundaries. When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
Detailed explanation-3: -Mid-ocean ridges form where two tectonic plates are pulling apart, also called seafloor spreading. Tectonic plates are large pieces of the earth’s crust, while divergent plate boundaries are the name given to the areas where the two plates are pulling apart.
Detailed explanation-4: -noun. ˈmid-ˈō-shən-: an elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma.
Detailed explanation-5: -Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).
