WebJun 8, 2024 · 2.4: Divergent Boundaries. At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two … WebDivergent boundaries. Geologic tension is also found in the tectonic regions of divergent boundaries. Here, a magma chamber forms underneath oceanic crust and causes sea-floor spreading in the creation of new oceanic crust. Some of the force that pushes the two plates apart is due to ridge push force of the magma chamber.

Convergent boundaries, also called destructive boundaries, are places where two or more plates move toward each other. Convergent boundary movement is divided into two types, subduction and collision, depending on the density of the involved plates. Continental lithosphere is of lower density and thus more …
In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional 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. Most active divergent plate boundaries occur between oce… WebThe rocks pulled down under the continent begin to melt. Sometimes the molten rock rises to the surface, through the continent, forming a line of volcanoes. About 80% of earthquakes occur where plates are pushed …
