What else can I help you with?
Are oceanic plates only made up of oceanic crust?
yes but oceanic crust is younger than continental crust because of deep sea trenches
Where are oceanic trenches?
plate tectonics
Deep-oceanic trenches are most abundant around the rim of the?
Deep-oceanic trenches are most abundant around the rim of the Pacific. Deep ocean trenches are surficial evidence for sinking of oceanic lithosphere into the mantle at a subduction zone.
What are the valleys under the ocean called?
They are called trenches.
What is the process by which oceanic crust sinks beneath the trenches?
Oceanic crust sinks beneath trenches through a process known as subduction. As oceanic plates collide with continental plates, the denser oceanic plate is forced downward into the mantle due to gravitational pull. This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.

What causes oceanic trenches?
Deep ocean trenches are made where one plate is submerged under another

What are the valleys under the ocean called?
They are called trenches.
Why are most oceanic trenches found in the pacific ocean?
The Pacific Ocean is part of the Ring of Fire. The ring of fire is underwater trenches made my moving plates. The plates pushed on each other and eventually moved downward, creating trenches
Oceanic crust returns to the mantle at deep ocean trenches which are?
rocks
What are valleys between the ridges on the ocean floor?
They are called oceanic trenches.
What is the process by which oceanic crust sinks beneath the trenches?
Oceanic crust sinks beneath trenches through a process known as subduction. As oceanic plates collide with continental plates, the denser oceanic plate is forced downward into the mantle due to gravitational pull. This creates a subduction zone where the oceanic crust eventually melts and is recycled back into the mantle.
What does an oceanic-oceanic convergence give rise to?
An oceanic-oceanic convergence occurs when two plates made of oceanic crust collide. This collision can lead to the formation of deep oceanic trenches, volcanic island arcs, and earthquakes. Over time, the denser plate may subduct beneath the other, leading to the recycling of oceanic crust back into the mantle.
What is the result when ocean floors spread?
oceanic trenches and volcanoes from the rising magma.
How do you contrast mid-ocean ridges and trenches?
Mid-ocean ridges are the birthplace of oceanic crust. Trenches represent the destruction and burial of oceanic crust. They are at opposite ends of the Earth's convection currents that move through the asthenosphere.
