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:

To determine the correct answer, we analyze each option:

• "By collecting drill core samples of Earth’s crust": Drill core samples from the crust are a direct way to study Earth's interior (crust) as they provide physical material for analysis.
• "By measuring seismic wave activity": This is an indirect method to study Earth's interior (like mantle, core) as seismic waves are analyzed to infer structure, not direct evidence.
• "By analyzing how living things survive": This relates to biology/ecology, not direct study of Earth’s interior.
• "By recording changes in climate patterns": This relates to climate science, not direct study of Earth’s interior.

So the correct option is the one about collecting drill core samples.

Answer:

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