Question

identifying sources used to study earth’s interior
which sources do scientists use to study the interior of earth? check all that apply.
earth’s orbit
core samples
sea level
earthquakes
s waves
rock composition

Explanation:

To determine the sources for studying Earth's interior:

• Earth’s orbit: Relates to Earth's movement around the Sun, not its interior. Eliminate.
• Core samples: Drilled samples from the Earth's crust can provide info about deeper layers. Valid.
• Sea level: Related to ocean surface height, not Earth's interior. Eliminate.
• Earthquakes: Seismic waves from earthquakes help map Earth's interior structure. Valid.
• S waves: Seismic S - waves (secondary waves) can't travel through liquid, helping identify the liquid outer core. Valid.
• Rock composition: Studying rock types and their composition gives clues about Earth's interior formation. Valid.

Answer:

core samples, earthquakes, S waves, rock composition
