each layer in earth has diffrent material that is cuse diffrent propertis. natural or man made Wave when it come from inside of the earth show difftent propertis .this is main reason of layering earth .
Scientists have determined the layers of the Earth by studying seismic waves from earthquakes. These waves travel through the Earth at different speeds and provide information about the density and composition of the different layers beneath the surface. By analyzing this data, scientists have been able to deduce the Earth's structure and layers.
Scientists study seismic waves to learn about the temperature inside the Earth's crust. By analyzing the speed and direction of these waves as they travel through different layers of the Earth, scientists can infer information about the temperature and composition of the Earth's crust.

Scientists study layers of rocks to learn about the earth and how it has changed. They know that if layers are undisturbed, the oldest rocks are on the bottom and the youngest rocks are on top. They know how old each layer is in relation to the other layers.
Scientists know about the existence of the different layers of the Earth primarily through studies of seismic waves generated by earthquakes. By analyzing how these waves travel through the planet, scientists can infer information about the density, composition, and structure of the various layers. Other sources of information include drilling samples and studies of rocks and minerals brought to the surface through volcanic activity.
Scientists use seismic waves from earthquakes to determine the depths of Earth's layers. The speed and behavior of these waves change as they pass through different materials, allowing scientists to infer the structure of Earth's interior. This technique, called seismic tomography, helps researchers map the boundaries between Earth's layers and understand their composition and properties.
In the earlier years of science, people found out and discovered this type of science, and that type of knowledge has been passed down through history for all to know +++ THAT does not answer the question! Our knowledge of the Earth's interior comes from analysing rocks emitted in volcanic eruptions and igneous intrusions, and from analysing seismic waves (vibrations) from earthquakes.
We know about the inside of the Earth through seismic waves, which are waves generated by earthquakes. These waves travel through the Earth and can be detected and measured by seismographs on the surface. By analyzing how these waves behave and interact with different materials inside the Earth, scientists can infer the composition and structure of the Earth's interior.

we should know it is our earth
Scientists know that gravity cause sediment to be deposite.
we know whats inside the earth because there is earthquake wave
