Question

how do geologists study direct evidence of earths interior?
by collecting drill core samples of earths crust
by measuring seismic wave activity
by analyzing how living things survive
by recording changes in climate patterns

Explanation:

Drill core samples are direct physical evidence from Earth's interior. Measuring seismic waves (B) is indirect (uses wave behavior). Analyzing living things (C) relates to biology, not Earth's interior. Recording climate (D) is about climate, not interior.

Answer:

A. by collecting drill core samples of Earth's crust
