What is a oceanic ridges?
a ridge in the ocean
What is mid - oceanic ridges?
mountainous topography
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What type of plate movement causes mid ocean ridges and sea floor spreading?
Divergent plate boundary movement causes mid-ocean ridges and sea-floor spreading. This occurs when two tectonic plates move away from each other, creating new oceanic crust at the boundary. Magma rises to the surface, solidifies, and forms undersea mountain ranges known as mid-ocean ridges.
Is Magma appears to be rising underneath the mid-oceanic ridges?
Yes, magma is constantly rising underneath mid-oceanic ridges due to the process of seafloor spreading. As tectonic plates diverge at these ridges, magma from the mantle rises to fill the gap, solidifies upon cooling, and creates new oceanic crust.

Where are the youngest portion of Earth's crust found?
The youngest parts of the Earth's crust are found in the oceanic crust. This crust is continuously being created at the mid-oceanic ridges.
What is mid - oceanic ridges?
mountainous topography
Where is oceanic crust created?
New oceanic crust is created at the mid-oceanic ridges, a divergent plate boundary.
What is the relationship between distance from the ridges and age of the crust?
At the oceanic ridges the age of igneous basalt rocks is approximately zero (as that is where they formed) and the rocks get older the farther away. The ages of sedimentary and metamorphic rocks does not correlate reliably with distance from the oceanic ridges like the ages of igneous rocks, because they can form anywhere not mainly at oceanic ridges. Igneous granite rocks are generally formed around continental volcanos not oceanic ridges.
Is it true that The Atlantic and Pacific basins have oceanic ridges and the Indian Ocean has no oceanic ridge?
yah
Does the oceanic lithosphere get older or younger?
Oceanic lithosphere gets older as it moves away from the mid-ocean ridges where new lithosphere is formed. This process, known as seafloor spreading, causes older lithosphere to be pushed further from the ridge, resulting in a gradient of lithosphere age with the oldest being farthest from the ridges.
Why does oceanic lithosphere sink at subduction but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
What are places where oceanic crust sinks back to the mantle?
No. Mid oceanic ridges are the places where new oceanic crust are forming.
What plates corresponde to mid ocean ridges?
Oceanic Plate.
Where are the youngest portions of the Earth's crust?
They can be found in Oceanic Ridges.
