Question

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

Answer 1

Answer:

As there are many forms of waves but the two main types of the waves are the electromagnetic form of ways and the mechanical form of waves inside a given space. While, the electromagnetic form of waves does not involves the medium for its travel inside a given region or between the source of generation to the point of destination.

• For, the mechanical waves all is not the same just because the different level of mediums are required to transfer the energy for a point of its generation to the point of destination inside a given space provided to the system.

• The seismic waves are generated by the point of source or the point of generations, as there are different source of seismic waves inside the universe. While, the different waves are generated inside the core of the planets, and seismic wave is one of those mechanical waves. As the seismic waves requires the different mediums for the transfer of the energy from one point or source of the generation to the point of the destination or the receiving end of the system.

• As there are about seven tectonic plates inside the planet's structure and as it is more obvious to know that there are certain movements of the plates inside the planets generating an enormous amount of energy in the form of seismic waves. These waves are generated at a certain point of source or generation point and are felt at a far distance from that very point of origin in the form of ground movement. These form of waves are in the form of longitudinal form of wave travel, as there are certain places on the wave structure where is an enormous amount of energy present known as the compression and then there are certain places inside the wave structures where the energy present is in less dense form called as the rarefaction.
• While,there are also different form of energy transfer systems which are important to study and take under-consideration.As there are waves inside the oceanic region, as theses waves travels in the form of mechanical waves and the type of propagation is more transverse in form. As the motion of medium's particles is moving in perpendicular to the motion of the energy,E inside the medium. While, there are no points of rarefaction or compression  on the waves structure.Because there is far more different perception of the transverse type of waves.
