It is caused by rcording of earthquake waves
Scientists study a variety of data, including seismic waves, rock samples, and magnetic properties of rocks, to develop the model of the Earth. By analyzing these data, scientists have been able to understand the Earth's composition, structure, and dynamics.
Seismic waves, specifically P-waves and S-waves, have been vital in creating a model of the Earth's interior. By analyzing how these waves travel through the Earth, scientists can infer details about the composition and structure of the planet's layers.
Scientists such as Niels Bohr and Ernest Rutherford used atomic spectra to develop models of the atom. They were able to study the unique wavelengths of light emitted by atoms and used this information to propose new atomic models that helped explain atomic structure and behavior.
The scientists test whether the model can be used to make accurate predictions. Scientists in 1750 would have not been able to develop a table like Mendeleev because there was only 17 known elements to work with, the scientists would not have enough data.

Scientists studied seismic waves generated by earthquakes to understand the behavior of waves as they travel through different layers of Earth. By analyzing the speed, direction, and intensity of seismic waves, researchers were able to infer the composition and structure of Earth's interior, leading to the development of models like the Earth's layers (crust, mantle, core).
Scientists studied data collected from seismometers left on the Moon's surface by Apollo missions, as well as data from lunar meteorites and satellite missions like the Lunar Reconnaissance Orbiter. By analyzing the Moon's seismic activity and gravitational field, scientists were able to develop a model of the Moon's interior structure, including its core, mantle, and crust.
If the data shows that a model is wrong, scientists will revise the model or develop a new one that better fits the observed data. They may also investigate the sources of error or uncertainty in the data and make adjustments accordingly. The scientific process involves constant refinement and improvement, so scientists are open to modifying their models based on new evidence.
Aristotle did not develop the geocentric model; it was proposed by earlier Greek astronomers. Aristotle supported this model in his work "On the Heavens" around the 4th century BCE, arguing that Earth was at the center of the universe.
Scientists of Hellenistic times believed the Earth was the center of the universe and that celestial bodies moved around it in perfect circular motion. In Columbus's time, scientists began to challenge this geocentric view, with Copernicus proposing a heliocentric model where the Earth orbits the Sun. This shift in thinking laid the foundation for the scientific revolution that followed.
Nicolaus Copernicus, Galileo Galilei, and Johannes Kepler were prominent scientists who challenged the Earth-centered view of the universe, known as the geocentric model. Copernicus proposed the heliocentric model, where the Earth and other planets orbit around the Sun. Galileo's observations with the telescope provided evidence for this heliocentric model, while Kepler refined it by discovering that planets move in elliptical orbits around the Sun.
A visual or mathematical representation used to develop scientific explanations is called a model. A model can be a diagram, graph, equation, or any other representation that helps scientists understand and explain a scientific phenomenon or process. Models are used to simplify complex concepts and aid in the development of theories and predictions.
