Quizplus · Accepted Answer

Scientists use seismic waves to study the Earth's interior and they analyze how these waves interact with different layers. However, to determine the composition of the core, they also use information from meteorites. Meteorites are believed to be remnants of the early solar system and have a similar composition to the Earth's core. Therefore, studying meteorites can provide insights into the core's composition.
