Answer:
The correct arrangement would be 3. magnetosphere, core, mantle, crust, hydrosphere, atmosphere.

40 percentage it's very less
Scientist use triangulation method to locate the epicentre of an earthquake from the data collected from Seismograph.
<u>Explanation:
</u>
The seismic data from three different location is collected to locate the intersect point as the epicentre point to be determined. Each earthquake is recorded in seismogram in different location.
A seismogram is the output from a graph called seismograph, which is used to determine the epicentre of an earthquake. There are two waves namely <em>P-waves or Primary waves and</em> <em>S-waves or secondary waves </em>that are considered while finding the epicentre of an earthquake.
With the seismogram, P-waves appears first before S-waves, since they travel faster through three states of matter. Thus, data from seismograph is used for locating “epicentre of an earthquake”.
