The buoyancy of the crust forces it upwards, the forces of the collisional stress balanced by gravity and erosion. This … WebOct 19, 2024 · In geology, a crust is the outermost layer of a planet.

Crustal - Definition, Meaning & Synonyms Vocabulary.com
WebA fracture zone is a linear feature on the ocean floor—often hundreds, even thousands of kilometers long—resulting from the action of offset mid-ocean ridge axis segments. They are a consequence of plate tectonics. Lithospheric plates on either side of an active transform fault move in opposite directions; here, strike-slip activity occurs.

WebConvergent boundary. A 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. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone. [1] WebMar 13, 2024 · New crust is formed at divergent boundaries on the ocean floor where the lithosphere is thin. Magma from the upper mantle presses against the plate, pushing it upward, then flows off in opposite directions at the plate. The plate, constructed of brittle lithosphere rock, is stretched by the movement of the convection and soon cracks. Weboceanic crust, the outermost layer of Earth’s lithosphere that is found under the oceans and formed at spreading centres on oceanic ridges, which occur at divergent plate boundaries. Oceanic crust is about 6 … bxt 58 a
