The ocean ridges push the old crust into a convergent boundary where it goes into a mantle convection current. The crust then melts in the convection current and is pushed out of the ocean ridge to restart the process again.

Where do midocean ridges intersect the landmasses?

Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.


What are the 3 type of earthquakes?

(1)midocean spreading ridges, (2) subduction zones, and (3) transform faults.Normal fault, Reverse fault, and strike-slip fault


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


Where are the midocean ridges offset the most by faults?

At transform faults or transform zones.


Is subduction characteristic of diverging plate boundaries?

No, subduction is not characteristic of diverging plate boundaries. Subduction occurs at converging plate boundaries where one tectonic plate is forced beneath another plate. Diverging plate boundaries are where tectonic plates move away from each other, such as at mid-ocean ridges.


Where can each boundary type be found on earth?

Divergent boundaries are found along mid-ocean ridges, convergent boundaries are found at subduction zones and mountain ranges, and transform boundaries are found along fault lines like the San Andreas Fault in California.

Is the Mid-Oceanic Ridge in the middle of the Atlantic Ocean?

One of the midocean ridges is, but others are in other oceans, seas, and bays.


How are oceanic ridges form?

divergent boundaries


What feature is not associated with subduction zones?

Mid-ocean ridges are not associated with subduction zones. They are divergent plate boundaries where tectonic plates are moving away from each other, leading to the formation of new oceanic crust. Subduction zones, on the other hand, are convergent plate boundaries where one tectonic plate is being forced beneath another.


Ocean ridges are formed by what boundaries?

Divergent boundaries form ocean ridges.


Why are the continents very young?
