WebD. Continental-Constructive convergence. 19. convergent plate boundaryat convergent boundary the crust is what Answer: At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. WebIt usually involves an oceanic plate and a continental plate. This movement can cause earthquakes and volcanoes. An example of this plate boundary or margin is where the Nazca and South...

In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Convergent boundary. election commitments 2017WebA convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
