GEOLOGY

Detailed explanation-1: -Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries-divergent, convergent, and transform.

Detailed explanation-2: -Rift Valleys Ultimately, they will form the floor of a new ocean. An example of this type of geological feature is the East African Rift Zone. This particular rift zone is called a triple junction because it represents the divergence of three plates, forming a “Y” shape.

Detailed explanation-3: -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-4: -Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.

Detailed explanation-5: -A convergent plate boundary, also known as a destructive plate boundary, usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. As the plates collide, the oceanic plate is forced beneath the continental plate.
