The age of the ocean floor is directly related to its distance from mid-ocean ridges due to the process of seafloor spreading. Mid-ocean ridges are underwater mountain ranges formed by tectonic plates pulling apart, which allows magma to rise from the mantle and solidify to create new oceanic crust.

As tectonic plates move apart at these mid-ocean ridges, new crust is continuously formed. This means that the youngest oceanic crust is located at the ridge itself, while the crust becomes progressively older as you move away from the ridge. Essentially, the farther you travel from the mid-ocean ridge, the older the ocean floor becomes.

This relationship can be summarized as follows:

1. **Youngest Crust at the Ridge**: The ocean floor is newest at the mid-ocean ridges due to ongoing volcanic activity and the creation of new material.

2. **Increasing Age with Distance**: As you move away from the ridge, the oceanic crust gets older. This is because the crust is continually being pushed away from the ridge as new material forms at the center.

3. **Age Determination**: Scientists can determine the age of oceanic crust through various dating techniques, and geological studies show a consistent pattern of increasing age away from the ridge.

In summary, the age of the ocean floor increases with distance from mid-ocean ridges, highlighting the processes of plate tectonics and seafloor spreading.
