A+ answer: all waves change directions as they travel through different materials
Earthquakes, volcanic eruptions, and the study of seismic waves are natural occurrences that help scientists learn about the layers of the Earth. By analyzing how these events interact with different layers of the Earth, scientists can infer properties such as composition, density, and thickness of the various layers beneath the surface.
The layer of Earth with the greatest amount of decayed material is the topmost layer, known as the soil layer or the humus layer. This layer contains organic matter formed from the decomposition of plants and animals, contributing to soil fertility.
The layer covering the Earth is called the crust. Another name for the crust is called the lithosphere.
crust and mantle, known as the Mohorovičić discontinuity or Moho. This boundary is where seismic waves change speed, indicating a transition between the Earth's outermost solid layer (crust) and the underlying denser layer (mantle).
The layer of the Earth you are referring to is the outer core. It is composed of molten iron and nickel, and its movement generates the Earth's magnetic field. This layer is located beneath the mantle and above the solid inner core.
Seismic Tomography is the most popular technique used to find the Earth's sub-surface characteristics.

studying seismic waves from earthquakes. These waves travel through the Earth and are affected by the different densities of materials in each layer. By analyzing how the waves change direction and speed as they pass through the Earth, scientists can infer the composition and structure of each layer.
Scientists use seismic waves from earthquakes to study the different layers of the Earth. By measuring the time it takes for these waves to travel through the Earth, researchers can infer information about the composition and structure of each layer. This technique is known as seismic tomography and has provided valuable insights into Earth's interior.
Scientists have identified the boundaries between Earth's layers by studying seismic waves generated by earthquakes. The speed and behavior of these waves as they travel through the Earth provide valuable information about the composition and structure of each layer. By analyzing seismic data, scientists can determine the boundaries between the crust, mantle, outer core, and inner core of the Earth.
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 use seismic waves from earthquakes to study the interior layers of the Earth. By analyzing how these waves travel through the Earth's layers, scientists can determine the properties of each layer, such as density and composition. This information helps us understand the structure and composition of the Earth's interior.
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.

Scientists have determined the composition of Earth's layers through a combination of techniques such as seismic data analysis, laboratory experiments on rock samples, and studying the chemical and physical properties of minerals. By examining how seismic waves travel through the Earth and how they are reflected and refracted at different boundaries, scientists have been able to gain insights into the composition of each layer.
Scientists determined that Earth has layers through various methods such as studying seismic waves from earthquakes, analyzing samples from drilling projects like the Deep Earth Sampling, and studying the behavior of materials under high pressure and temperature in laboratory experiments. These methods provide evidence for the composition and properties of Earth's layers, including the crust, mantle, outer core, and inner core.
Scientists believe that the Earth's inner core is most likely made of solid metals, primarily iron and nickel. This is supported by seismic wave data and studies on the Earth's magnetic field.
