Answer

The direction of the plate motions, how fast the plates are moving, and the location of modern plate boundaries. Explanation 1. Identify the Purpose of Sea Floor Age Maps A map of the ages of the sea floor primarily shows the **direction of the plate motions** and **how fast the plates are moving**. This is because the age distribution indicates how new crust forms at mid-ocean ridges and moves away, revealing both direction and speed. 2. Analyze Additional Information While it can suggest the **location of modern plate boundaries**, it does not directly show **how much material was produced at the ridges during a given period of time**.
