One way is from seismic waves, which are formed when earthquakes occur.
From gravity and magnetic surveys and from seismic information.
To study earth's interior, geologist often rely on indirect methods such as evidence from seismic waves, not fossils.
Geologists learn about Earth's interior using indirect evidence from seismic waves, magnetic field data, and rock samples from volcanoes and deep drilling. These methods help provide insights into the composition, structure, and properties of Earth's interior layers.
Geologists obtain indirect evidence about the earth's interior by reactions to seismic waves. They also use rock samples and drilling samples.
they have used two methods direct and indirect. seismic waves are the forces produced when earthquakes occur.from rocks from deep inside earth they can give inferences about conditions deep inside earth. they also record the seismic waves and record how dast they travel through Earth this is an indirect method
Rock samples and Indirect evidence from seismic waves Direct evidence from rocks samples and indirect samples from seismic waves my science teacher told me
Geologists use seismic waves, rock samples, and magnetic and gravity data to study the structure of the Earth. By analyzing these pieces of evidence, geologists can gain insights into the composition and layers of the Earth's interior.
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.
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.
People who study the Earth are often called geologists. Geologists study the Earth's processes, materials, and history to better understand its composition and structure.
