Question

What kind of indirect evidence do geologists use to study the structure of Earth?

Option 1: Fossils
Option 2: Seismic Waves
Option 3: Magnetic Anomalies
Option 4: Rock Layers

Answer 1

Geologists use fossils, seismic waves, magnetic anomalies, and rock layers as indirect evidence to study the structure of Earth.

Step-by-step explanation:

Geologists use various indirect evidence to study the structure of Earth. Some examples of indirect evidence used by geologists include:

1. Fossils: Fossils of ancient sea life found on dry land far from oceans provide evidence of Earth's changing history and the movement of continents.
2. Seismic Waves: Seismic surveys, using sound waves, can help geologists create an 'image' of what lies beneath Earth's surface. Different types of rock or sediment can affect the characteristics of these waves.
3. Magnetic Anomalies: Geologists study magnetic anomalies to understand the distribution and movement of Earth's tectonic plates.
4. Rock Layers: The study of rock layers, known as stratigraphy, can provide valuable information about Earth's history and the sequence of events.
