A subduction zone occurs at convergent plate margins where an oceanic plate is going underneath a continental plate or a less dense oceanic plate. A mid-ocean ridge is a divergent plate boundary on the ocean floor with a mountain range and a rift running through the center of it. Sea floor spreading also occurs at mid ocean ridges.
What else can I help you with?
What forms when one oceanic plate is forced beneath another plate a. an ocean basin b. an ocean ridge c. a subduction zone d. a rift valley?
C. subduction zone
What is the difference between ridge push and slab pull?
Ridge push is a gravitation force that causes a plate to move away from the crest of an ocean ridge, and into a subduction zone. The Slab pull force is a tectonic plate force due to subduction. The difference is the force of motion.
What is the process whereby the weight of an uplift ocean ridge pushes an oceanic plate toward a subduction zone?
The weight of the uplifted ocean ridge creates a downward force on the oceanic plate, causing it to be pushed towards a subduction zone. As the plate moves, it eventually descends into the mantle at the subduction zone due to gravitational forces, leading to the formation of a deep ocean trench.
What geologic feature results when divergence occures between two oceanic plates?
a mid oceanic ridge
What forms when one oceanic plate is forced beneath another plate a rift valley an ocean basin an ocean ridge a subduction zone?
A subduction zone forms when one oceanic plate is forced beneath another plate. This process can lead to the formation of volcanic arcs, deep ocean trenches, and seismic activity.
Does subduction occur at the mid ocean ridge?
No, the Mid Atlantic Ridge is where the two plates are diverging, which creates more oceanic floor.
What is the process called when the oceanic plates slide down the slope of lithosphere-asthenospher boundary?
The process is called "subduction." It occurs when one tectonic plate moves beneath another at a convergent boundary, where the oceanic plate is forced down into the mantle at a subduction zone. This process leads to the recycling of old oceanic crust back into the mantle.
What is difference between ocean ridges and rises?
Ridges and Rises are uplifts in oceanic crust caused by volcanic eruption in oceans, the difference between a ridge and a rise is of rift valleys, ridges have long valleys and rises do not have any valleys
How are the sections of oceanic crust on either side of the ridge moving?
The sections of oceanic crust on either side of a mid-ocean ridge are moving away from each other due to seafloor spreading. As magma rises from the mantle at the ridge, it solidifies to form new oceanic crust, pushing the older crust outward. This movement is driven by tectonic forces, including mantle convection and the pull of subduction at oceanic trenches. Consequently, the ocean floor is continuously being renewed and expanded.
Is oceanic crust near the mid-ocean ridge older thean oceanic crust farther away from the ridge?
Its oceanic crust
What is the difference between a mid ocean ridge and a rift?

What is similar between ocean trench and mid-ocean ridge?
Both the ocean trench and mid-ocean ridge are features found on the ocean floor as part of the oceanic crust. They are formed by tectonic processes, with ocean trenches created by the subduction of one tectonic plate beneath another, while mid-ocean ridges are formed by the divergence of tectonic plates, leading to the upwelling of magma and the creation of new oceanic crust.
