when this earth cooled from being hot, all the Iron and Nickle get concentrated inside earth forming inner two layers Inner solid core and outer liquid core. Then with the passage of time earth solidifies gradually and mantle solidifies and now at this stage our crust the outer most part of earth look like its final product.
Scientists believe that Earth has four layers (crust, mantle, outer core, inner core) based on seismic waves produced by earthquakes and volcanic activity. These waves travel through the Earth at different speeds and behave differently depending on the properties of the material they travel through, allowing scientists to infer the presence of distinct layers with varying densities and compositions. This model helps explain Earth's structure and how it influences geological processes.
Scientists send seismic waves through the earth. These travel at different speed according to the density of the material that they travel through. When they bounce back, scientists use these data to guess what the earth is made up of.
Earth scientists use two different ways of classifying the Earth's layers because they have distinct properties and characteristics. The chemical composition provides information about the materials that make up the layers, while the mechanical properties inform us about how the layers behave under stress and pressure. Both classifications are important for understanding the Earth's structure and dynamics.
Scientists use seismic waves to study Earth's layers by analyzing how they travel through the different materials that make up the Earth. The speed and direction of seismic waves change as they encounter different densities and compositions in the layers of the Earth, providing valuable information about the structure of the planet's interior. By measuring the arrival times and characteristics of seismic waves at different locations, scientists can infer details about the depth, density, and composition of Earth's layers.
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.

Shooting seismic waves into the planet
Scientists believe that the layers of the Earth were formed through a process called differentiation, where heavier materials sank towards the center, forming the core, while lighter materials rose to the surface, forming the crust. This process occurred early in Earth's history when the planet was still molten, allowing for the separation of materials based on their density.

Your mom made the earths layers
Type your answer here... D.Comparing the composition of the crust to other bodies in the solar system
== ==
they made one layer.. waited for that to dry, then kept making layers till it became this :) hope i helped you out haahaha
The oldest organisms can generally be found in the lower layers of rock, as these layers were formed earlier than the upper layers. By examining the relative positions of different rock layers, scientists can determine the ages of the organisms found within them.
which layers of the earth have scientists been able to explore
No
