Ocean Ridges And Trenches. The crust of the earth is covered with oceanic and continental plates. Where are the oceanic ridges located?
Mid-Ocean Ridge - Wikipedia from en.wikipedia.org
Mantle convection drives plate tectonics. Oceans have three more important features like oceanic trenches, plains, and ridges. Ocean trenches are steep depressions in the deepest parts of the ocean [where old ocean crust from one tectonic plate is pushed beneath another plate, raising mountains, causing earthquakes, and forming volcanoes on the seafloor and on land.

What is ocean trenches and ridges? Oceans have three more important features like oceanic trenches, plains, and ridges. This is where one plate is sinking beneath another.

Very deep, elongated cavity bordering a continent or an island arc; A mid ocean ridge is a divergent boundary where plates are moving apart, an ocean trench is a convergent boundary where plates are moving together. Earthquakes occur along all plate boundaries, consequently they provide an ideal demarcation of individual plates.

Ocean ridges and trenches the extreme earth: C inside volcanoes of the ring of fire. D in deep ocean trenches.
It Helped To Establish The Theory Of Plate Tectonics In The 1960S.
Trenches occur at convergent plate boundaries. Very deep, elongated cavity bordering a continent or an island arc; The types of rocks found in these ocean trenches are also asymmetrical.
B Far From Tectonic Plate Boundaries.
Two oceanic plates collide at a convergent boundary, and the older, denser plate subducts (goes under) the other plate. Midocean ridges plates spread apart new lithosphere forms earthquakes on normal faults the ocean crust is almost entirely mafic: Convection currents push these plates together and apart.
