Which is a method that scientists use to determine the composition of earths layers?
Shooting seismic waves into the planet
The Earth's interior cannot be directly observed. Scientists must rely on indirect data to make hypotheses about the interior. Indirect evidences include meteorite composition, volcanic ejecta, intrusive igneous rock exposed through erosion, and the behavior of seismic waves as they travel through the Earth. They porduce youmama and fu yall It is difficult to determine Earth's inner structure because of all the layers. The Earth altogether is made up of seven layers.
Severals methods are all combined to give the scientist info on the layers of the Earth. For example they study the influence of the earth on orbits of the moon and other planets (mass distribution of the earth, mass density). They study the way seismic waves go through the earth which gives knowledge of layers. They use wave to sound. They examine sample of earth.
