Answer

Answer:

They point out a surprising fact and then give more details about it.

Brief Explanations:

The first paragraph presents the surprising fact that the mid - ocean ridge system is the most extensive mountain chain on Earth. The second paragraph then provides details such as the percentage of it that is underwater (more than ninety percent), its length (65,000 kilometers), and the average water depth to the top of the ridge (2,500 meters).
