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: -A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.

Detailed explanation-3: -The features most commonly associated with divergent boundaries between tectonic plates are rift valleys, ocean ridges, fissure volcanoes, and underwater mountain chains.

Detailed explanation-4: -The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation.

Detailed explanation-5: -New oceanic lithosphere forms at divergent plate boundaries. As plates move away from each other the lithosphere thins and tears. At these divergent plate boundaries new oceanic lithosphere is created in the gaps from upwelling magma from the mantle.
