Question

Which of the following best describes how scientists study the interior of the Earth?

a.Scientists use seismic waves alone to study the Earth's interior.
b.Scientists use seismic waves, gravity, and magnetism to study the Earth's interior.
c.Scientists dig deep holes to access and study the Earth's interior.
d.Scientists use only seismic waves and gravity to study the Earth's interior.

Answer 1

Scientists study the Earth's interior using seismic waves, gravity, and magnetism to create a model of the liquid and solid layers inside the Earth.

Step-by-step explanation:

The best description of how scientists study the interior of the Earth is that scientists use seismic waves, gravity, and magnetism to study the Earth's interior.

This approach allows them to construct a model of Earth's interior, revealing its liquid and solid layers. Seismic waves behave similarly to sound waves, reflecting and refracting through the Earth's layers, which vary in composition and density. These waves provide vital information when detected by a network of seismographs.

Additionally, Earth's gravity and magnetic fields offer cues to the distribution of mass and the composition of different layers within the planet.
