direct evidence from rock samples and indirect evidence from seismic waves
Scientists use seismic waves to study Earth's interior. Seismic waves travel through the Earth and can be detected far from their source.
the rock record provides evidence of past human civilizations

Scientists use mainly fossils.
Scientists use a variety of evidence to study prehistoric times, including fossils, geologic strata, archaeological artifacts, DNA analysis, climate data, and isotopic analysis of elements found in ancient specimens. By examining these different types of evidence, scientists can reconstruct past environments, track the evolution of species, and understand human history.

they use primary resorces!
How do scientists use seismic waves to study the Earth
Scientists use a variety of evidence to study early migration, including genetic analysis of modern and ancient populations, archaeological artifacts, isotopic analyses of human remains to trace diet and geographic origin, and studies of ancient pollen and plant remains to reconstruct past environments. By combining these different lines of evidence, scientists can piece together the story of how humans migrated and settled around the world.
Satellite-based telescopes and sensors.
They use direct evidence from rock samples and indirect evidence from seismic waves.
Indirect evidence from Seismic Waves, and direct evidence from rock samples.
they use stuff like earthquakes and volcanoes to study it.
