They can learn a lot about the past, or how the earth used to be. The landscape of the earth in the past.
that the earth's Poles switch every few 100'000 years of more, and find different organisms that lived on earth

Scientists learn about the layers deep within the Earth's crust by studying how seismic waves travel through the Earth. ... By looking at the time of arrival of the main set of waves, and how the frequencies of the waves are arranged within the set, scientists can learn about the density and other properties of the layers.

Determine the age of the layers of rocks
Scientist learn about the earth's interior by studying seismic waves. 'P' waves travel all the way through Earth's crust, mantle, outer and inner core and give scientists a glimpse of the interior.

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.
They have given us important information about the internal structure of the Earth.
Scientists can learn about the past by studying various sources such as fossils, ice cores, sediment layers, and historical documents. By analyzing these sources, scientists can piece together information about events, climates, and life forms that existed in the past. These studies help provide insights into how the Earth and its inhabitants have changed over time.
Scientists learn about the layers deep within the Earth's crust by studying how seismic waves travel through the Earth. If there is an earthquake somewhere, seismographs in many locations will record it. By looking at the time of arrival of the main set of waves, and how the frequencies of the waves are arranged within the set, scientists can learn about the density and other properties of the layers. The relative differences in arrival times of the S and P seismic waves at several recording stations tell scientists about the different speeds those waves were traveling at, which in turn gives information about the density of the material the layer is made of, and how thick the layer is in several directions.
