Respond to the following based on your reading.
Why can seismic waves be used to determine structures and materials within the earth?
Answers
Answer:
earth quakes are measured using seismograph
Epicenter of an earthquake can be measured with the help of seismograms that are located at three different locations and its magnitude can be determined with the help of Richter scale
Explanation:
The epicenter refers to that particular point above the point of origin of an earthquake and it can be located with the help of seismograms that are to be placed at least in three distinct seismographic locations.
The Richter scale is a commonly used scale that helps in determining the magnitude of an earthquake. It can be calculated by determining the wave that has the highest magnitude.
Rayleigh and love waves are two of the earthquake seismic waves that are confined to the near surfaces areas.
Seismic shadow zone- This refers to those areas on the surface of the earth where the waves propagating through the interior of the earth does not arrive at the surface on the other end due to the process of seismic refraction method.
Triangulation- It is an efficient method used by geologists and seismologists in order to locate the earthquake epicenter.
Rayleigh waves- These are surface waves that can cause vertical motion and it also affects the water bodies such as lakes.
Love waves- These are surface waves that causes horizontal motion.
Seismic waves are helpful in determining the internal structure of the earth, because these waves namely P and S waves shows different properties at different depths and different layers, due to the differences in their densities and composition.
