WebA rift valley is a lowland regionthat forms where Earth’s tectonic plates move apart, or rift. Rift valleys arefound both on land and at the bottom of the oceanand are created by the process ofseafloor spreading. Rift valleys differ from river valleys and glacial valleys in that they are created by tectonic activityand not the process of erosion. engineer goby max size

WebJun 8, 2024 · Continental rift zones occur in weak spots in the continental lithospheric plate. A mid-ocean ridge usually originates in a continental plate as a rift zone that expands to the point of splitting the plate apart, with seawater filling in the gap. The separate pieces continue to drift apart and become individual continents. WebWide swaths of scattered earthquakes may also correspond to continental rift zones, such as in eastern Africa.

Evidence of Plate Motions - Geology (U.S. National Park Service)

A rift valley is a linear shaped lowland between several highlands or mountain ranges created by the action of a geologic rift. Rifts are formed as a result of the pulling apart of the lithosphere due to extensional tectonics. The linear depression may subsequently be further deepened by the forces of erosion.

WebOct 8, 2024 · Rift zones are long cracks in the Earth’s crust between the tectonic plates. They are generally over 1000km long, 30-100km wide and up to 10km deep.

WebRift valleys are created by plate tectonics. Tectonic plates are the huge rocky slabs made up of the Earth's crust and upper mantle. They are constantly in motion—shifting against each other, falling beneath one another (a process called subduction), crashing against one another. Tectonic plates also tear apart from each other. WebForty million years ago, a large tectonic plate, known as the Farallon Plate, was between the Pacific and North American plates. Subduction of the Farallon Plate beneath the entire West Coast created a line of volcanoes from Alaska to Central America. 20 Million Years Ago

WebThe idea of “plate tectonics” put together old ideas about continental drift with new data showing seafloor spreading.

WebIn rift valleys, the crust is pulled apart by tectonic forces, causing the formation of a valley. Oceanic trenches form at subduction zones, where one tectonic plate is pushed under another and into the mantle. As the plate descends, it bends and forms a deep trench.
