Scientists have been able to determine the composition of earth's layers using various ways. In most cases, samples have been taken and studied so as to determine the layers of the earth.
They dig and measure the layers with a ruler
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.
making inferences based on data from seismic waves.
The four layers that constitute the earths atmosphere in order from space to the earths surface are as follows: Inosphere (aka. Aurora) @ 350km, Mesosphere @ 90-350km, Stratosphere @ 50-90km, and Troposhere @18-50km. It's composition is 79% Nitrogen, 20% Oxygen, and 1% other gases.
Well, one way is that scientist study things from Earth's layers that have been pushed up through the crust.

Earth's layers classified by their composition and their physical properties.

Your mom made the earths layers
there are 7 layers in earths mantle.
