The mid-ocean ridge is formed by the long accumulation of ocean floor sediments and millions of years of their subsequent folding and faulting.

a. True

b. False

Respuesta :

The correct answer is B. false. 
The mid-ocean ridge is not formed by this accumulation of ocean floor sediments and their folding/faulting, but rather by plate tectonics. So, mantle underwater rises, creating this underwater mountain range, because two tectonic plates meet.
