(d) As the S-waves travel through the upper and lower mantle, the speeds of the waves change.(i) Describe and explain this change in speed.(if) Describe the effect of this change in speed on the path taken through the mantle by the S-waves. 相关知识点: 试题来源: 解析 (d)(i...
At that depth, the S-waves cannot propagate, while at the same time P-wave velocity is drastically reduced. S-waves are unable to travel through fluids. Thus, if S-waves were to encounter a fluid like region of Earth's interior, they would be absorbed there and would not be able to ...
waves are unable to travel through fluids.Thus, if S-waves were to encounter a fluid like region of Earth's interior, they would be absorbed there and would not be able to continue.Geophysicists believe this is what happens to S-waves as they enter the outer core.As a result, the S-...
1. Understanding Sound Waves: - Sound waves are classified as mechanical waves. This means they require a medium to travel through, unlike electromagnetic waves which can travel through a vacuum. 2. Identifying the Types of Mediums: - There are three primary types of mediums through which ...
On the other hand, in fluids, mechanical waves propagate only as longitudinal waves, which are called acoustic waves, since shear deformations are not allowed and transverse or shear waves cannot propagate. The question now becomes if coordinate transformations on the elastodynamic equations preserve ...
B. Let your pen follow the waves of thought. C. The second draft of the essay should be better. D. First of all, learn the technique of nonstop writing. E. Too many writers try to get their drafts right the first time. F...
S-waves:S-waves are seismic waves that moves through the different solid layers of the earth. It is also called a secondary wave because it is around 40 % slower than the primary wave.Answer and Explanation: Yes, S-waves are also an example of a shear wave. They are transverse waves ...
increase in the temperature of rocks through which body waves are traveling will cause a decrease in velocity, whereas an increase in confining pressure will cause a corresponding increase in wave velocity.In a fluid where no rigidity exists, S-waves cannot propagate and P-waves are markedly ...
Nevertheless, after decades of intensive research, it is still unclear how foreshock waves traverse through the bow shock and the downstream magnetosheath, populated by shocked solar wind plasma (Fig. 1a). This paper addresses the important question of the interaction of low-frequency waves with ...
