What is the role of mid-ocean ridges in ocean crust production?

Question

1)they subduct continental crust
2)they are sited of plate divergence where new crust forms
3)they cause ocean currents
4)they are inactive tectonic zones

Answer 1

The correct answer is:

2. they are sites of plate divergence where new crust forms.

Mid-ocean ridges are underwater mountain ranges formed by plate tectonics, specifically at divergent boundaries where tectonic plates are moving apart. As the plates separate, magma rises from the mantle to fill the gap, solidifying to form new oceanic crust.
