Answer:
At Convergent Boundaries:
Subduction
Island arcs
Volcanic mountains
At Divergent Boundaries:
Mid-ocean ridges
Rift valleys
Plates pulling apart
Magma breaks through crust
Magma flows from cracks
Explanation:
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
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.
Divergent boundaries occur in the rifts of the oceanic ridge system, including the Mid-Atlantic Ridge and the East Pacific Rise, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
