HELP PLEASEEE

How do we know what is inside the Earth? (How do we know the Earth has layers?)

(if you put a random answer for the points i will report)

Answer 1

Scientist use special technology to figure out what is inside of the Earth

Answer 2

Scientists know about the layers of the earth by sending sound waves through the earth. Because layers of different densities will allow sound waves to travel through them differently, we can study the sound waves to understand the layers of the earth.
