Heavier, more dense material, tended to sink in the early molten mass, while lighter, less dense material, rose toward the surface. Separation into layers was based on density. The separation seems to have taken place shortly after the formation of the planet in an event called the "Iron Catastrophe".

TaigaEarth is layered due to a process called differentiation, which occurred during its formation. Heavier materials like iron sank towards the core, while lighter materials rose towards the surface, creating distinct layers like the crust, mantle, outer core, and inner core. These layers have unique chemical compositions and physical properties that contribute to Earth's structure and behavior.

Why is the earth layered?
The Earth is layered due to differentiation during its formation. Heavier materials sank to the core, forming the inner layers like the core and mantle, while lighter materials rose to the surface, creating the crust. This layering is caused by the Earth's heat and pressure distribution, as well as the chemical composition of different materials.
How did earth's interior get its layered structure?
Earth's layered structure is a result of the differentiation process that occurred early in its history. Heavier elements sank towards the center, forming the dense core, while lighter materials rose towards the surface, leading to the formation of the crust. The heat generated by radioactive decay and residual heat from Earth's formation has also played a role in shaping the layered structure of the planet.
Which type of planets have a layered structure?
Terrestrial planets, like Earth, Venus, Mercury, and Mars, have a layered structure with distinct crust, mantle, and core layers. Gas giants like Jupiter and Saturn also have layered structures, consisting of a core surrounded by layers of different densities of gases such as hydrogen and helium.
How do the different densities of earth materials relate to the layered structure of the geosphere?
The layered structure of the geosphere is a result of the varying densities of earth materials. Heavier materials, like iron and nickel, sank to the core, forming the dense inner core. Lighter materials, such as silicates and oxides, rose to form the less dense outer layers, like the crust and upper mantle. This differentiation of densities led to the distinct layers within Earth.
What is the most common precambrian fossil are layered mounds of calcium carbonate called?
Stromatolites are the most common Precambrian fossil, which are layered mounds of calcium carbonate formed by microbial communities. These structures provide important clues about early life on Earth and the evolution of ancient ecosystems.
