And even though S waves can't travel through the liquid outer core, they do exist in the solid inner core. c. The deep mantle is more plastic than the lithosphere. This observation led to the discovery of the liquid outer core. You can make shear waves by, for example, tying a rope to a tree and shaking the free end of the rope up and down or side-to-side. Primary wave or compression wave. They usually result from an earthquake, volcanic eruption or other explosion. under volcanic islands. answer choices. d. The deep mantle is more silica-rich than the lithosphere. earthquake, the travel paths of the P and S waves start to touch the edge of the Earth’s outer core. The wave moves because one row of atoms moves sideways and pulls the next row with it, until the bonds between the rows pulls the second row back with an elastic-type recoil. What you will see is explained here. Join now. Log in. Where is the thickest part of the Earth's crust? The outer core is liquid so the s-waves cannot travel through this causing an “s-wave shadow” on the opposite side of the earth from the earthquake where the waves cannot be detected. S waves cannot pass through the liquid outer core, but P waves can. They are low frequency, long wavelength, and transverse vibration. Post navigation. Earthquake waves. For those through the core the same procedure has been followed as described by Gutenberg [1958a, p. 241]. Since the outer core is fluid, and S-waves cannot travel through a fluid, the "S-wave shadow zone" is even larger, extending from about 100° to 180°. Another way to prevent getting this page in the future is to use Privacy Pass. P waves travel through any type of medium, whereas S waves only move through solid environments — not liquid. Ask your question. Which earthquake waves travel through the outer core a Only P waves b Only P from CDE 2E at Central Bicol State University of Agriculture - Pili Main Campus (formerly CSSAC-Pili) Generally, which type of earthquake waves travel with the slowest velocity? An S wave is a different beast. Which earthquake waves travel through the outer core? Q. S-waves travel through solids, but not through liquids. SURVEY . Cloudflare Ray ID: 61202db11b981752 P-waves travel through both solids and liquids. Beyond this distance, the first arriving wave — the P wave — decreases in size and then disappears. - 3283535 1.

Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. A p-wave shadow is caused by refraction. P-waves can pass through the outer core. Question 3 6.25 pts Which statement correctly describes Earth's interior? If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Then continue to label the seismic waves: a. P waves – travel the quickest and can go through the liquid and solid cores. Please enable Cookies and reload the page. Usefulness of P and S waves in locating an event [ edit ] The hypocenter/epicenter of an earthquake is calculated by using the seismic data of that earthquake from at least three different locations. S waves only travel through solids and do not travel through the liquid outer core of the Earth. Love waves and Rayleigh waves were discovered by two Englishmen. Question 2 6.25 pts Why do earthquake waves travel faster through the deep mantle than through the lithosphere? As the outer core of the Earth is hot molten metal, S-waves do not pass through it. P-waves may be transmitted through gases, liquids, or solids. PKIKP: adding mantle → outer core → inner core → outer core → mantle. P waves, S waves, and Surface waves Below that depth, earthquake waves suddenly travel much slower, indicating a profoundly different material. Theoretical travel times of waves originating at the earth's surface have been calculated on the basis of the tables of Jef]reys and Bullen [1940] for waves through the mantle. Vertical motion seismographs record earthquakes by producing a squiggly diagram called a. seismogram. Love waves. 1. Learn about the behaviours of all the seismic waves. Use the diagram in Fig.4 above to answer these questions. The P-wave then travels through the outer core, the inner core, the outer core, and the mantle. a. Tags: Question 3 . They start to appear beyond 140 degrees.
