From class, earthquake is any shaking or rapid motion of the Earth's solid layer. the plate tectonics cause stress on rocks which leads to breakage and breakage causes energy which causes earthquake :)
There are also different types of Earthquake waves such as P. Waves, S. Waves, and Surface Waves
-P.Waves: "Primary" or "push-pull" and it travel faster than other waves
-S. Waves: "Secondary" or "side-to-side" and it leaves the epicenter at the same time as the P. Waves but travel slower and it reaches the location after the P.waves hit
-Surface wave is the strongest and it only travel on the crush. it is a combo of the P. and S. waves
An earthquake is the sudden release of energy from the crust of the Earth, that results in a seismic wave. Using a seismograph, the interior of the Earth is mapped, finding the epicenter (origin) and magnitude (strength) of the quake.
I believe this because she just explains it very nicely & if you are to search up chromosomes definition, you'll see that her answer is very identical.
For this you are going to use S as the dominate and r for the recessive. Since both of the parents are squared eye the offspring's likely chance of having round eyes will be 0%.
