How does the rate of ocean crust formation change?

Question

1)it is constant regardless of tectonic activity
2)it depends on mid-ocean ridge length and plate motion rate
3)it solely depends on ocean water temperature
4)it is influenced by atmospheric conditions

Answer 1

The rate of ocean crust formation primarily relates to mid-ocean ridge activity, which includes the length of mid-ocean ridges and the rate at which tectonic plates move apart. Therefore, the correct answer is:

2) it depends on mid-ocean ridge length and plate motion rate.

Mid-ocean ridges are where new oceanic crust is formed as magma rises to the surface, and the rate of formation can vary based on the geological activity and characteristics of these ridges.
