GEOLOGY

Detailed explanation-1: -Scientists are able to understand Earth’s interior by studying seismic waves. These are waves of energy that travel through Earth, and they move similarly to other types of waves, like sound waves, light waves, and water waves.

Detailed explanation-2: -Knowing how the waves behave as they move through different materials enables us to learn about the layers that make up the Earth. Seismic waves tell us that the Earth’s interior consists of a series of concentric shells, with a thin outer crust, a mantle, a liquid outer core, and a solid inner core.

Detailed explanation-3: -So scientists rely on seismic waves-shock waves generated by earthquakes and explosions that travel through Earth and across its surface-to reveal the structure of the interior of the planet.

Detailed explanation-4: -Seismic waves They are the most important source available to understand the layered structure of the earth. The velocity of seismic waves changes as they travel through materials with different elasticity and density.

Detailed explanation-5: -Seismologists use seismic waves to learn about earthquakes and also to learn about the Earth’s interior. One ingenious way scientists learn about Earth’s interior is by looking at earthquake waves.
