Want this question answered?
A seismic wave, or an earthquake.
Earthquake waves travel fastest in the interior of the Earth, as speed of waves increases as we go inside the Earth. The speed of a wave depends on the properties of the medium it travels in. The wave propagates faster in the denser and heavier core.
The boundaries of tectonic plates and the internal structure of the earth.
Scientists use seismic waves to map Earth's interior by using seismographs that measure the times at which seismic waves arrive at different distances from an earthquake.
Earthquakes are apart of geology. Geology is the study of Earth and Earth's interior, where as geography is Earth's climate and geographical features. I hope I helped answer your question. :)
Earth's interior...
The focus of an earthquake is the point in the earth's interior where energy is release.
Earthquake waves
Focus or Hypocenter
the focus
A seismic wave, or an earthquake.
Focus or Hypocenter
The Tectonic Plates.
the point in the interior of earth from where earthquake is orginated .
Scientists have determined what the interior of the earth is like through analyzing seismic or earthquake wave
