Earthquake waves travel faster in rocks that are more dense so observing them shows the density layering of the Earth. Also some waves can not pass through liquids and this shows us that there is a liquid core to the Earth.
Without the image it is impossible to say
It shows that the rock is a plutonic rock and was formed as a result of slow cooling within the earths crust/interior.
the earths crust is made up of huge plates that are floating very slowly and they move in different directions.when they touch or rub against each other it causes an earth quake
show the structure for haber process
Seismographs cannot measure volcanoes. When you research about seismographs, it may show thing about volcanoes. This is because right before a volcano erupts, it can cause little earthquakes and seismographs measure earthquakes!
By a pen moving on a piece of paper to show the magnitude
Earthquakes explain and support tectonic plate theory and show the movements of the plates over time. Fault lines also expose rock layers and allow geologists to study the rocks and the changes in the environment over time.An Earthquake gives out Seismic waves which. There are Primary Waves (P-Wave) and Secondary waves (S-Wave) The Secondary Seismic wave can't travel through liquid so when the sensors detect a wave and sees that some part the S-wave isn't going through a layer of the earth they know that that layer of the earth is Liquid.

that the earthquakes can and will ouccer in certen spots. it also show that there can be reppeded earthquakes in the same magnitued
