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. The Mid-Atlantic Ridge is an example of divergent plate boundaries .

Detailed explanation-2: -The Earth’s outer crust (the lithosphere) is composed of a series of tectonic plates that move on a hot flowing mantle layer called the asthenosphere. Heat within the asthenosphere creates convection currents that cause tectonic plates to move several centimeters per year relative to each other.

Detailed explanation-3: -Divergent boundaries exist where tectonic plates move apart from each other. Unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each.

Detailed explanation-4: -When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed.
