Which examples are indirect evidence used to study Earth's interior? Check all that apply.
ch4aika [34]

<u>Answer</u>:

Indirect evidence used to study Earth's interior are

  • analysis of several seismographs  
  • location of an earthquake's epicentre  
  • identification of seismic wave direction

<u>Explanation</u>:

The earth is mainly divided into 3 layers. These are the crust, mantle and the core. Further, the interior part of the earth cannot be studied directly and the direct evidence explains the composition of rocks.

The seismic waves help with the understanding of indirect evidence. The seismic waves are the energy that travels through different layers of the earth.It is caused due to  volcanoes, earthquakes, landslides etc. Thus, analysis of several seismographs, identifying the direction the of seismic wave and location of earth’s epicentre helps to study earth's interior.
