P-waves may be transmitted through gases, liquids, or solids. Q. surface waves. c. The deep mantle is more plastic than the lithosphere. P waves that travel through the outer core are called the PKP waves. In 1906, while investigating the speed of earthquake waves as a function of their depth within the Earth, Oldham found that the speed of earthquake waves becomes faster with greater depth of penetration into the Earth, but only to a certain depth. Log in. 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. Unlike P waves, S waves cannot travel through the molten outer core of the Earth, and this causes a shadow zone for S waves opposite to their origin. They start to appear beyond 140 degrees. answer choices. S-waves can pass through the outer core. P-waves . Tags: Question 3 . They can still propagate through the solid inner core: when a P wave strikes the boundary of molten and solid cores at an oblique angle, S waves will form and propagate in the solid medium. As we know today, that Inner core is solid, outer core is liquid. When an earthquake occurs, it releases waves of energy, which are known as Seismic waves. For this reason, there is also an S wave shadow-zone. This is based on the travel 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°. Question 2 6.25 pts Why do earthquake waves travel faster through the deep mantle than through the lithosphere? Join now. The deep mantle is hotter than the lithosphere. The deep mantle is more silica-rich than the lithosphere. 1 and 3 make perfect sense but neither is the answer, P-waves … What you will see is explained here. Vertical motion seismographs record earthquakes by producing a squiggly diagram called a. seismogram. under volcanic islands. S-waves travel through solids, but not through liquids. P-waves are longitudinal waves similar to sound waves which is why they are able to pass through the Earth's core. b. Good Vibrations What Earthquakes Can Tell Us About The Earth. The deep mantle is denser than the lithosphere. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Please enable Cookies and reload the page. earthquake, the travel paths of the P and S waves start to touch the edge of the Earth’s outer core. The seismic shadows are the effect of seismic waves striking the core-mantle boundary. A visualization of earthquake waves traveling both through Earth's interior and radiating outward on the surface. P waves travel through any type of medium, whereas S waves only move through solid environments — not liquid. Love waves and Rayleigh waves were discovered by two Englishmen. Which earthquake waves travel through the outer core - 5446544 1. Ask your question. 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.
