How Are Mid Ocean Ridges And Trenches Similar

Explanation: Mid ocean ridge are where new crustal material is forced to the surface. The new crustal material is pushed apart forming two different plates moving in two different directions. An ocean trench is where old crustal material is pushed under another plate where it is melted and turned into magma.

How are mid-ocean ridges and trenches related?

The oceanic lithosphere is formed at an oceanic ridge, while the lithosphere is subducted back into the asthenosphere at ocean trenches. Two processes, ridge-push and slab pull, are thought to be responsible for spreading at mid-ocean ridges.

Are ocean ridges and trenches the same?

Ocean ridges are boundaries where plates are being created, whereas trenches are boundaries where plates are being destroyed (subducted).

How are mid-ocean ridges and deep ocean trenches related to plate tectonics?

Convection currents push these plates together and apart. Convection currents are created by rising and falling heat in the earth’s mantle. When two oceanic plates are pushed away from each other, magma rises to the surface between the plates and creates a ridge.

What do ocean trenches have in common?

In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.

How are ocean ridges and trenches related?

Ocean ridges are boundaries where plates are being created, whereas trenches are boundaries where plates are being destroyed (subducted). Earthquakes occur along ALL plate boundaries, consequently they provide an ideal demarcation of individual plates.

How are mid-ocean ridges and trenches similar and different?

Explanation: Mid ocean ridge are where new crustal material is forced to the surface. The new crustal material is pushed apart forming two different plates moving in two different directions. An ocean trench is where old crustal material is pushed under another plate where it is melted and turned into magma.

How do mid-ocean ridges and trenches form?

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

How are trenches and ridges related to plate tectonics?

At convergent boundaries, plates collide with one another. The collision buckles the edge of one or both plates, creating a mountain range or subducting one of the plates under the other, creating a deep seafloor trench.

What is another name for ocean trenches?

deep-sea trench, also called oceanic trench, any long, narrow, steep-sided depression in the ocean bottom in which occur the maximum oceanic depths, approximately 7,300 to more than 11,000 metres (24,000 to 36,000 feet). They typically form in locations where one tectonic plate subducts under another.

What are ocean ridges called?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics.

How are ocean ridges linked with ocean trenches?

1 Answer. Hannah M. Under-water trenches and ridges are created by plate tectonics.

How are ocean ridges and deep ocean trenches related to plate tectonics?

Convection currents push these plates together and apart. Convection currents are created by rising and falling heat in the earth’s mantle. When two oceanic plates are pushed away from each other, magma rises to the surface between the plates and creates a ridge.

These mid-ocean ridges are a range of volcanic hills found underwater. The flowing mantle material out of these mid-ocean ridges forms the new oceanic crust.
