Seismic tomography helps in understanding:
(a) Earth’s magnetic poles reversal
(b) Earth's internal structure and density variations
(c) Weather patterns in the troposphere
(d) Plate movements on the surface
Explanation Seismic Waves: Earthquakes generate seismic waves that travel through the Earth's interior. Speed Variations: The speed of these waves changes depending on the density and composition of the materials they pass through. Imaging Technique: Seismic tomography uses the variations in the travel times of these waves to create 3D images of the Earth's interior. Revealing Structure: This technique helps scientists understand the distribution of different materials (like solid rock, molten rock, and even the core) within the Earth.
