Core samples provide us with actual samples rocks from inside Earth. They are considered direct evidence of the Earth-s interior. Seismic waves are a form of energy that travels through or across Earth and helps scientists infer what is inside Earth. They are indirect evidence.
Explanation:
Core samples are direct evidence of what is inside the Earth because they take a direct sample of the rocks that make up the layers of the Earth-s surface and core. Geological core samples can indicate to researchers variations in weather patterns and climate changes through time. There can also be evidence of species and and the sedimentary composition of lake beds and rivers for example. Core samples provide direct evidence of the dynamic nature of the Earth's formation and how it changes through time. Seismic waves help to tell where there are variations in the Earth's composition. Geologists can study seismograms to discern about the different content of the Earth's internal structure like which parts are solid, molten or composed of gases.
