The p-wave shadow zone
Webb27 sep. 2024 · The shadow zone of P-waves appears as a band around the earth between 103° and 142° away from the epicentre. This is because P-waves are refracted when they pass through the transition between the semisolid mantle and the liquid outer core. What causes a shadow zone quizlet? A seismic shadow zone is an area of the Earth's surface where seismographs cannot detect direct P waves and/or S waves from an earthquake. This is due to liquid layers or structures within the Earth's surface. The most recognized shadow zone is due to the core-mantle boundary where P waves are refracted and S … Visa mer The earth is made up of different structures: the crust, the mantle, the inner core and the outer core. The crust, mantle, and inner core are typically solid; however, the outer core is entirely liquid. A liquid outer core was first … Visa mer Although the core-mantle boundary casts the largest shadow zone, smaller structures, such as magma bodies, can also cast a shadow … Visa mer The main observational constraint on identifying liquid layers and/or structures within the earth come from seismology. When an earthquake occurs, seismic waves radiate … Visa mer • Seismic wave • Ray tracing (physics) • P wave Visa mer

Webb6 apr. 2024 · P-wave shadow zones are formed due to refraction, which causes the waves to deviate away. But S-wave shadow zones are created because these waves are … WebbThe P wave shadow zones are due to the fact that P waves travel faster in solids than liquids; This means that the P waves slow down as they enter the liquid outer core. This causes them to refract (i.e. change direction). They also refract when they leave the …
WebbSeismic Shadow Zones: P wave The shadow zone is the area of the earth from angular distances of 104 to 140 degrees from a given earthquake that does not receive any direct P waves. The different phases show how the … WebbWhat would be the effect on the P-wave shadow zone? a) It would be smaller b) It would be larger c) It would increase in some places and decrease in others d) It would cease to exist because the inner core is solid; The variation in velocity with radius within the mantle transition zone is a result of
Webb14 apr. 2015 · The shadow zone of a P-wave exists from 105 to 143 degrees (epicentral distance). This is caused by P waves meeting the liquid outer core and being refracted.

This shadow zone has led geologists to a …
