Final answer:
Scientists use seismic waves, gravity, and magnetism to study the Earth's interior.
Step-by-step explanation:
Scientists use seismic waves, gravity, and magnetism to study the Earth's interior. Seismic waves are produced by earthquakes and provide valuable information about the Earth's structure and composition. Gravity is used to study the distribution of mass within the Earth, while magnetism helps identify magnetic anomalies that can indicate the presence of certain materials.
