Question

one piece of evidence that supports the theory of plate tectonics is found in the observation of rocks on either side of the mid - atlantic ridge, shown in the picture provided. plate tectonic theory is supported because as you move out form the mid - atlantic ridge, the rocks -
are increasingly older.
have higher iron content.
become thicker and thicker.
are made of smaller particles.

Explanation:

At mid-ocean ridges like the Mid-Atlantic Ridge, new oceanic crust is formed from magma that cools and solidifies. As tectonic plates move away from the ridge, new crust continues to form at the ridge axis. This means rocks farther from the ridge were formed earlier, so they are increasingly older. This pattern of seafloor spreading is key evidence for plate tectonics.

Answer:

A. are increasingly older.
