Explanation:
The above statement is the statement that is too narrow in the passage. A "too narrow" statement is one that gives a detail of what the main passage is talking about. Also, it helps the reader to visualize a part of what the passage is talking about. Yet it does not still provide enough information for one to grasp the whole passage. Also, such statement gives a specific idea or concept from the story or passage.
The above statement is "too narrow" because it actually states a single part of the overall passage and also gives a very specific idea from the passage.
the oldest ocean floor is only 180 million years old, because the oldest crust is destroyed at subduction zones.

What are subduction zones?</h3>
According to NOAA, tectonic plates are fragments of the Earth's hard outer layer that steadily travel across the surface of the globe over millions of years (opens in new tab). (This is a fundamental principle of the theory of plate tectonics, which holds that pieces of the Earth's crust slide across the lower mantle and carry continents with them.) According to the U.S. Geological Survey(opens in new tab), the Earth's crust and the top part of the mantle, a thick, heated layer under the crust, make up that outer layer, also known as the lithosphere (USGS). This lithosphere material curls downward into the heated mantle during subduction zones, when two tectonic plates collide and one slides beneath the other.
