What tool was instrumental in the discovery of the earth's interior? Question 9 options:

GPS - radio waves helped scientists determine the layers of the earth

Awl - drilling helped scientists determine the layers of the earth

Seismograph - earthquakes waves helped scientists determine the layers of the earth

Sonar - sound waves helped scientists determine the layers of the earth

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
