Question

the two types of evidence geologists use to learn about earths interior.

Explanation:

Geologists use two primary types of evidence to study Earth's interior: direct evidence from rock samples (like drill cores or exposed deep rocks) that show the composition of shallow layers, and indirect evidence from seismic waves, which change speed and direction as they travel through different materials, revealing the structure and properties of deeper layers.

Answer:

1. Direct evidence: Rock samples (drill cores, exposed deep crustal rocks) that reveal the composition of Earth's shallow interior layers.
2. Indirect evidence: Seismic waves, whose speed and path changes as they pass through different Earth materials, allowing geologists to infer the structure, density, and state of matter of deeper interior layers.
