What type of evidence geologist use to learn about earths interior?

Geologists use several types of evidence to study Earth's interior, including seismic wave data, which reveals how waves travel through different layers of the Earth. They also analyze rock samples from the surface and deep drilling projects, as well as meteorite compositions, which provide insights into the materials that make up the Earth's interior. Additionally, models of Earth's magnetic and gravitational fields help infer the properties and behaviors of subsurface materials.
