Play this game to review science. They move because of something called convection currents.

Mid ocean ridge are where new crustal material is forced to the surface.
Mid ocean ridge and deep ocean trench. Most of the ridge system lies beneath more than a mile of open ocean, with an average distance of 8,200 feet (2,500 meters) from the water’s surface to the ridge’s top. Most of the earth's geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes.
The oceanic lithosphere is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at ocean trenches. (two other unmanned expeditions have also explored the challenger deep.) It lies below the lithosphere between approximately 80 and 200 km (50 and 120 miles) below the surface.
Name the process occurring at b and explain what results from it. The sediments near a mid ocean ridge on the youngest sedimentary layer. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a.
(a) subduction of ocean crust beneath other ocean crust, forming a trench/trough and ridge, with flanking hilly abyssal plain and volcanogenic seamounts; Only three people have visited the challenger deep, the deepest ocean trench in the world: An ocean trench is where old crustal material is pushed under another plate where it is melted and turned into magma.
The asthenosphere is almost solid although some of. An example of a trait that would be considered acquired and inherited is a. This rift marks the actual boundary between adjacent tectonic plates, where magma from the mantle reaches the seafloor, erupting as lava and producing new crustal material for the plates.
Tren… a location where two tectonic plates come together 2 terms jacob_swanson85 science subduction deep ocean trench Convection currents push these plates together and apart. What is a deep ocean trench?
The asthenosphere is almost solid although some of. See answer (1) best answer. A process by which oceanic crust sinks down beneath the trench into the mantle.
The crust of the earth is covered with oceanic and continental plates. A volcanic mountain that rises above the surface of the water is called _____ How are mid ocean ridges and trenches similar?
These plates are moving constantly but are moving very very slowly. What happens to old oceanic. 1 show answers another question on biology.
A process where part of the ocean floor sinks to the mantle to form a trench. At a convergent boundary with at least one oceanic plate, an ocean trench It lies below the lithosphere between approximately 80 and 200 km (50 and 120 miles) below the surface.
