What causes the layered structure of the earth?

Answer 1

Differing densities in the materials present inside the planet.

The interior of the earth contains a number of substances, all of which have a unique density, which is how many atoms are present inside a given unit of space. Density determines wheather things sink or float in water. If a substance's density is lower than that of waters, it will float, if it is higher, it will sink. Same goes for substances in the earth. If a substance has a lower density, it will rise towards the surface. If it has a higher density, it will go to the earth's core.

Answer 2

As the Earth was molten early in its history, heavier materials sank towards the center, creating the core, while lighter materials rose to the surface, forming the crust. This process, known as planetary differentiation, led to the distinct layers of the Earth: the inner core, outer core, mantle, and crust. This process is the main cause of the Earth's layered structure.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
