Why do scientists classify the earth's core into an inner and outer layer?
Hazel AsherThe inner and outer core have different composition and are considered separate layers.
The solid inner core is believed to be composed of massive iron crystals and is mostly iron with trace amounts of heavy elements.
Liquid iron-nickel alloy with trace amounts of heavier elements makes up the outer 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.
