Although scientists cannot directly observe Earth’s mantle or core, they can learn about these regionsindirectly by observing the behavior of seismic waves from earthquakes. Seismic waves come in twobasic forms (see figure). Pressure (P) waves move material back-and-forth in the direction of the waves'motion. Compressing and expanding a slinky will produce this sort of oscillation. Shear (S) waves, on theother hand, move material side-to-side in directions perpendicular to the waves' motion. The oscillationsof a jump rope, a guitar string, and the ocean surface are all examples of shear waves. Because seismicP- and S- waves are created by different kinds of motion, they interact with Earth matter in different ways. Please sort each wave type according to the types of Earth matter it travels through
