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.
What is the relationship between the oceanic ridges and the trenches?
Trench: very deep, elongated cavity bordering a continent or an island arc; it forms when one tectonic plate slides beneath another. Ridge: underwater mountain range that criss-crosses the oceans and is formed by rising magma in a zone where two plates are moving apart.
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.
Mid-ocean ridges are spreading centers, they are divergent plate boundaries where magma wells up from below, creating new oceanic crust. Ocean trenches form where crustal plates plunge back into the mantle. Thus, these long, narrow depressions are associated with convergent plate boundaries.
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.
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 the same?
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 would you explain between ridges and trenches?
Answer: Trench is a very deep, elongated cavity bordering a continent or an island arc; it forms when one tectonic plate slides beneath another. Ridge: underwater mountain range that crosses the oceans and is formed by rising magma in a zone where two plates are moving apart.
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.
What’s the difference in a trench and a ridge?
Trench: very deep, elongated cavity bordering a continent or an island arc; it forms when one tectonic plate slides beneath another. Ridge: underwater mountain range that criss-crosses the oceans and is formed by rising magma in a zone where two plates are moving apart.
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 is the difference between mid-ocean ridge and Mid-Atlantic Ridge?
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world.
What is the relationship between seafloor spreading mid-ocean ridges and ocean trenches?
Matching magnetic lines of reversal along both sides of the ocean ridge also lends support to the theory of sea floor spreading. The subduction zones which form the deep sea trenches also support the theory of sea floor spreading.
How do plate tectonics explain ocean ridges and trenches?
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.
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. 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 divergent boundary.
How tectonic plate movements result in the formation of ridges and trenches?
In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21). Hot magma rises to the crust’s surface, cracks develop in the ocean floor, and the magma pushes up and out to form mid-ocean ridges.
What do mid-ocean ridges and hotspots have in common?
The buoyant rise of hot material transports heat to the surface from the deep interior while colder material sinks at subduction zones. Mid-ocean ridges and hotspots are major expressions of heat dissipation at Earth’s surface, as evidenced by their abundant volcanic activity.
More Answers On How Are Ocean Ridges And Trenches Related

How are mid ocean ridges and trenches similar?
Jun 8, 2020Mid ocean ridges occur at constructive plate boundaries where 2 oceanic plates are moving apart. Ocean trenches occur in front of subduction zones, also known as destructive boundaries. This is where one plate is sinking beneath another. Where the plate being subducted goes down it forms a very deep trench. Click to see full answer.
Feb 7, 2022Ocean ridges and trenches are related in a few ways. One of the ways is being created from the movement of tectonic plates on the mantle when they diverge and converge. When tectonic plates diverge they “pull apart” and create trenches. When they converge they “push together” and create ridges, subduction happens here.
How did you learn about mid ocean ridges and ocean trenches without hearing about plate tectonics? They are all related processes. Mid ocean ridges are spreading zones for plate movement. Deep ocean trenches are subduction zones for plate melting and recycling. You just don’t find a subduction zone adjacent to a spreading zone.
Feb 28, 2018 Under-water trenches and ridges are created by plate tectonics. Explanation: The crust of the earth is covered with Oceanic and Continental plates. These plates are moving constantly but are moving very very slowly. They move because of something called convection currents. Convection currents push these plates together and apart.
ocean trench | National Geographic Society
May 20, 2022Ocean trenches formed by this continental-oceanic boundary are asymmetrical. On a trench’s outer slope (the oceanic side), the slope is gentle as the plate gradually bends into the trench. On the inner slope (continental side), the trench walls are much more steep. The types of rocks found in these ocean trenches are also asymmetrical.
Ocean Trenches – Woods Hole Oceanographic Institution
Trenches are formed by subduction, a geophysical process in which two or more of Earth’s tectonic plates converge and the older, denser plate is pushed beneath the lighter plate and deep into the mantle, causing the seafloor and outermost crust (the lithosphere) to bend and form a steep, V-shaped depression.
