When one of the plates is an oceanic plate, it gets embedded in the softer asthenosphere of the continental plate, and as a result, trenches are formed at the zone of subduction. Rivers, mountain ranges, oceans, and deserts can all serve as physical boundaries. Here, convection currents are driving apart the North American plate (moving West) and the Eurasian Plate (moving East) along a constructive or divergent plate boundary. When subduction occurs, a chain of volcanoes often develops near the convergent plate boundary.

Each of these types of plate boundaries is associated with different geological features.Typically, a convergent plate boundarysuch as the one between the Indian Plate and the Eurasian Plateforms towering mountain ranges, like the Himalaya, as Earths crust is crumpled and pushed upward. What tectonic plate uplifts the Andes Mountains? Plate Boundary: Divergent (Fast-spreading Ridge) New oceanic crust is created at this boundary when basalt magma, formed in the mantle, rises into fractures in the crust and solidifies. These trenches are some of the deepest places in the ocean, and they are often the sites of strong earthquakes.When subduction occurs, a chain of volcanoes often develops near the convergent plate boundary. Plate Tectonics guide for KS3 geography students - BBC Bitesize What is the type of plate boundary between the Arabian Plate and the African plate? The prevailing hypothesis for the Rockies birth, called flat-slab subduction, says that the Pacific oceanic plate dove underneath the North American plate at an unusually shallow angle.
