GEOLOGY

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.

Detailed explanation-2: -Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle.

Detailed explanation-3: -When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.

Detailed explanation-4: -Divergent boundaries form where convection cells in the mantle bring large amounts of hot, molten mantle rock to the surface. This most commonly occurs in oceanic crust, which covers most of Earth’s surface.

Detailed explanation-5: -At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth’s mantle. Seafloor spreading creates new crust.
