What type of plate boundary is the Mid-Atlantic Ridge?

1. Oceanic-Continental

2. Continental-Continental

3. Oceanic-Oceanic

4. Transform

The correct answer is: Oceanic-Oceanic

The Mid-Atlantic Ridge is a divergent plate boundary where two oceanic plates are moving away from each other. This means that the correct answer is C Oceanic-Oceanic. Option A is incorrect because it describes a boundary where an oceanic plate is subducting under a continental plate, which is not the case for the Mid-Atlantic Ridge. Option B is incorrect because it describes a boundary where two continental plates are colliding, which also does not apply to the Mid-Atlantic Ridge. Option D is incorrect because it describes a boundary where two plates slide past each other, which is more commonly found at transform plate boundaries.
