Contrast the feature of continent continent plate boundaries with those of the ocean ocean plate boundaries

Answer 1

Continent-continent plate boundaries are characterized by the collision of two plates composed of continental crust. This collision can result in the formation of mountain ranges, such as the Himalayas, as the plates are forced upwards and into each other. These boundaries are considered to be passive margins and are not typically associated with seismic activity.

On the other hand, ocean-ocean plate boundaries occur when two plates composed of oceanic crust converge or diverge. In convergent boundaries, one plate is typically subducted beneath the other, resulting in the formation of deep ocean trenches and volcanic island arcs. In divergent boundaries, new crust is formed as magma rises to the surface and cools, creating mid-ocean ridges. Ocean-ocean plate boundaries are often associated with volcanic activity and frequent earthquakes.

Overall, continent-continent plate boundaries are characterized by their lack of volcanic and seismic activity, while ocean-ocean plate boundaries are known for their distinct geological features, including volcanic island chains and deep ocean trenches.
