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: -At transform boundaries, tectonic plates are not moving directly toward or directly away from each other. Instead, two tectonic plates grind past each other in a horizontal direction. This kind of boundary results in a fault-a crack or fracture in the earth’s crust that is associated with this movement.

Detailed explanation-3: -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-4: -A transform plate boundary occurs when two plates slide past each other, horizontally. A well-known transform plate boundary is the San Andreas Fault, which is responsible for many of California’s earthquakes.
