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 simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
