You can find the elevations by finding the contour interval and each line up count up
<h2>Answer: D. Rayleigh wave
</h2>
Rayleigh waves are a type of surface acoustic wave that causes particles on the surface of solids to travel along an elliptical path in the vertical plane that contains the direction of wave propagation.
These waves include longitudinal (P wave) and transverse (S wave) movements whose amplitude decreases exponentially as the distance from the surface increases.
This means Rayleigh waves are generated by the interference between the P and S waves on the surface of the Earth.
Wikipedia isn’t a reliable resource. From what I gather from another website was, “The Bible describes the Garden of Eden lying between the confluence of the four rivers. The Turks say those four rivers are the headwaters of the Tigris, Pison, Gihon and Euphrates rivers in modern Turkey. “
