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 Earth’s crust provide direct material to study. Valid.
• Sea level: Reflects ocean surface height, not interior structure. Eliminate.
• Earthquakes: Seismic waves (like P and S waves) from earthquakes reveal interior layers (e.g., S waves don’t travel through liquid, indicating outer core is liquid). Valid.
• S waves: Seismic S - waves (secondary waves) help map Earth’s interior by their behavior (e.g., refraction, reflection, and inability to pass through liquid). Valid.
• Rock composition: Studying rock types (e.g., from crust or mantle - derived rocks) gives clues about interior materials. Valid.

Answer:

B. core samples, D. earthquakes, E. S waves, F. rock composition
