In the wonderful words of Schulz, “Take your hands and hold them palm downs, middle fingertips touching. … The place where they meet is the Cascadia subduction zone. Now slide your left hand under your right one. That is what the Juan de Fuca is doing: sliding steadily beneath North America (Schulz)”. She understands not all of her readers will understand her article completely until they understand how the earthquake will happen. This hand demonstration is a very clever technique used by Schulz. Once the readers comprehend the way the earthquake will happen, they would want to continue reading and would have a better understanding of her point and realize how accurate she is. This method she used, is effective because she allows the readers to understand this text even if they have no knowledge about …show more content…

Meaning, the earthquake is bound to happen at any given moment. Using history to aid her case is influential because she is using legitimate sources to support her claims. Schulz is justifying her argument of the earthquake to come in the near future and nobody is taking any action to prepare for
