Why is earth's core made of iron?
Iron is the heaviest of the most abundant elements and it sank to the centre.
About 30% of the Earth's mass is made up of iron, which is abundant in our galaxy according to spectroscopic analysis. Iron would have sank to the center of the Earth during its molten state, leading scientists to believe that massive iron crystals make up the inner core of the planet.

The Earth's core is predominantly made of iron due to several factors, including the abundance of iron in the Earth's composition, its high density, and its ability to withstand high temperatures and pressures found in the core. Additionally, during the Earth's formation, heavier elements like iron sank towards the center due to gravitational forces, leading to the concentration of iron in the core.

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.
