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:

• Option A: Drill core samples are direct physical evidence from the Earth's crust. Geologists can analyze the composition, structure, and properties of these samples to understand the interior.
• Option B: Measuring seismic wave activity is an indirect method. Seismic waves provide information about the Earth's interior based on how they travel through different materials, but it is not direct evidence like a physical sample.
• Option C: Analyzing how living things survive is related to biology and ecology, not directly to studying the Earth's interior.
• Option D: Recording changes in climate patterns is related to meteorology and climate science, not to the study of the Earth's interior.

Answer:

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