![]() ![]() You can see this beautifully in the second illustration that has provided: The crust is not thicker under the rift, rather it floats up. The resulting new crust is warmer than the older material surrounding it and therefore has higher buoyancy: it floats more easily and rests higher on the magma below, forming a ridge in relation to the colder, older, more heavy material around it. The Mid-Atlantic Ridge has been created by seafloor spreading: the plates drift apart and the rift is filled with magma from below. Hyperleap helps uncover and suggest relationships using custom algorithms. Now that we know the terminology, we can look at the Mid-Atlantic Ridge. What do Mid-Atlantic Ridge, African Plate and Plate tectonics have in common. According to plate tectonics, these ridges run along a divergent boundary, which occurs where the plates are moving away from one another. The German term for a graben is Graben (literally "trench"). The illustration below is from Wikipedia. rift-valley or grabenĪ graben or rift valley is formed where tectonic plates move away from each other and part of the broken crust sinks. ![]() The German term for an oceanic trench is Tiefseerinne (literally "deep sea groove"). has also provided an illuminating illustration. Sea Floor Spreading Magnetic mapping of the ocean floor revealed a history of polarity reversals that formed a mirror image about the Mid-Atlantic Ridge. It does not store any personal data.Let's clear up the terminology first: trenchĪ trench, as has described in their answer, is formed where tectonic plates move towards each other and one of the plates is subducted under the other.
