The process by which the seafloor moves apart at mid-ocean ridges is called a. subduction b. polarization c. sea floor spreading d. mountain formation

I think the answer would be C, because to me that's one that makes sense, I hope that I could help, Have a great Thursday!

C. Sea floor spreading.

Explanation:

The geological process by which the tectonic plates separate from each other in the seabed allowing the rise of magma is known as sea floor spreading.

In this process, magma comes into contact with cold water and solidifies rapidly, generating a ridge at the bottom of the ocean, as is shown in the image.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
