Geologists use seismic waves to map the Earth's interior. By studying how these waves travel through the Earth, geologists can infer information about the composition and structure of different layers beneath the surface. This helps them understand the different layers of the Earth, such as the crust, mantle, and core.

Convection of liquid metals in the outer core creates the Earth's magnetic field.
Shadows can provide information about the depth and direction of geological features, such as mountain ranges or volcanic peaks, on the surface of the Earth. By studying the lengths and angles of shadows, geologists can infer the approximate shape and elevation of land formations, helping to better understand the Earth's interior composition and structure.
Geologists study the Earth's interior. They also study the Earth's composition and all the processes that cause it to change.
Geologists cannot directly observe Earth's interior. Instead, they use indirect methods such as seismic waves, gravity studies, and geothermal measurements to infer the characteristics and composition of the Earth's interior. These methods provide valuable insights into the properties of the Earth's layers without the need to physically access them.
No. Fossils tell us about what was living at or near the earths surface in the past, they do not tell us about the Earth's interior. When studying the Earth's interior, geologists look at micro gravity variations (which tell us about density differences in deep rocks), magnetic variations (which tell us a bit about the deep rocks composition) and most importantly seismic records (which tell us about the physical properties of the deep rocks). We also look for deep rocks that have been brought to the surface during the collision of continents (the roots of mountains) and volcanic events (such as diamond pipes).
Studying how seismic waves refract inside the earth and if they "cast shadows" indicating that some layers inside earth are opaque to some types of seismic waves. Seismic waves "illuminate" the interior of the earth like light waves illuminate a room, permitting what is there to be seen if you have the correct tools to observe them.
