The difference in composition is what caused the Earth to develop layers as it cooled.!Differences in density caused earth to develop layers as it cooled.The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle.

seismic waves.
When lava cools and solidifies, magnetic minerals within it align themselves with Earth's magnetic field. By studying the orientation of these minerals in lava layers, scientists can track changes in the Earth's magnetic field over time. Reversals of the Earth's magnetic field are reflected in lava layers as bands of alternating magnetic orientation.
Earth is layered due to gravitational compression that caused dense materials to sink onto the Earth's center, while the less dense materials rose.
When magma cools deep inside earth, igneous rockforms.
Igneous rock layers are formed from the cooling and solidification of molten rock, known as magma or lava. When magma cools beneath the Earth's surface, it creates intrusive igneous rocks, while lava that cools on the surface forms extrusive igneous rocks. These layers can vary in composition and texture, depending on the rate of cooling and the minerals present. Over time, geological processes may expose these layers, allowing them to be studied in formations such as mountains or cliffs.
