True or false? Aluminum is the third most abundant metal in the earth's crust. Thanks
Wyatt AdkinsAl is the third most abundant element in earth's crust (not metal).
Oxygen, silicone, aluminum, iron, calcium, sodium, potassium, magnesium, titanium, and hydrogen are the most abundant elements in the earth's crust.
The first three (percent by weight) are: oxygen (46.1%) silicone (28.2%) aluminum (8.23%).

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.
