Evaluate the drafted changes
The lead section clearly describes a shadow zone. The sentence: "The reason for this is that the velocity for P-waves and S-waves is governed by both the different properties in the material which they travel through and the different mathematical relationships they share in each case," could begin by referring to the shadow zone (instead of stating "The reason for this," and could be rewritten as "The velocity of P-waves and S-waves are governed by the properties of the material in which they travel through, which include: incompressibility, density, and rigidity.

The final section could be broken up into subsections describing 'P-waves' and 'S-waves' separately, including the formulas that describe their activity.

The final statement on the geologist who recognized shadow zones could be referred to in the lead. A section on his work could be included in the Article body, as well as a photo if available.

The references should be included in the correct format. Citations need to be included in the article.
