Thus, crust is cracked and broken at transform margins, but is not created or destroyed. In contrast to convergent and divergent boundaries, no magma is formed. As the plates alternately jam and jump against each other, earthquakes rattle through a wide boundary zone. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. Two plates sliding past each other, Natural or human-made structures that cross a transform boundary are offset-split into pieces and carried in opposite directions. Transform boundaries (Conservative) Transform plate boundaries Thus at convergent boundaries, continental crust, made of granite, is created, and oceanic crust is destroyed. Magma formed from melting plates solidifies into granite, a light colored, low-density rock that makes up the continents. Magma rises into and through the other plate, solidifying into new crust. If one of the colliding plates is topped with oceanic crust, it is forced down into the mantle where it begins to melt. Plate Boundary Types Divergent boundary (Constructive) Plate boundary zones: broad belts in which boundaries are not well defined and the effects of plate interaction are unclear.Transform boundaries: where crust is neither produced nor destroyed as the plates slide horizontally past each other.Convergent boundaries: where crust is destroyed as one plate dives under another.
Divergent boundaries: where new crust is generated as the plates pull away from each other.Convergent boundaries - where crust is destroyed as one plate dives under another. There are four types of plate boundaries: Divergent boundaries - where new crust is generated as the plates pull away from each other. “Read More about: What is Plate Tectonics? “ What are the 4 types of plate boundary?
Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. Plate boundaries are the edges where two plates meet. This image shows the three main types of plate boundaries: divergent, convergent, and transform.
