WebThe movement of faults at plate boundaries can provide a convenient pathway for magma to reach the surface. It helps to explain this by looking at the three main types of plate boundary: constructive boundaries (divergent): where plates are moving away from each other as new crust is created between the two plates WebSep 27, 2024 · In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense litho sphere melts or slides beneath …

WebMay 20, 2024 · A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates. One example of a ridge is the … 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 oceanic plates and exist as mid-oceanic ridges. WebFeb 11, 2024 · Introduction. The landscapes of our national parks, as well as geologic hazards such as earthquakes and volcanic eruptions, are due to the movement of the large plates of Earth’s outer shell.
