Identify three other clues about earth interior
1. Seismic waves: The way seismic waves travel through the Earth's interior can provide valuable information about its composition and structure. For example, the speed at which seismic waves travel can indicate the density and temperature of the materials they are passing through.
2. Magnetic field: Earth's magnetic field is generated by the movement of molten iron in the outer core. By studying changes in the magnetic field over time, scientists can gain insights into the dynamics of the Earth's interior.
3. Volcanic activity: Volcanic eruptions provide clues about the composition and temperature of the Earth's mantle and core. The type of volcanic rocks and materials ejected during an eruption can reveal information about the processes occurring deep within the Earth's interior.
