Answer 1

We know about the inside structure of the Earth through drilling holes and studying earthquakes.

Step-by-step explanation:

There are two main ways we know about the inside structure of the Earth: drilling holes and earthquakes. By drilling deep into the Earth's crust, scientists can retrieve samples and study the composition of different layers. Earthquakes provide valuable information through the study of seismic waves. These waves travel through the Earth and can be analyzed to determine the density and composition of different layers.
