The four layers of the Earth are called the inner core, the outer core, the mantle and the crust. In addition, there are two different types of crust. The continental crust is the part that is under land, and the oceanic... More »

The primary heat source for the Earth is the radioactive decay of uranium, thorium and potassium, found in the mantle and crust. The Earth produces more heat through phase changes, such as the freezing of liquid iron in ... More »

Banana peels are chemically composed of potassium, phosphorus, calcium, manganese, sodium, magnesium and sulfur. Potassium is by far the most common element, composing as much as 42 percent of dried banana peels. More »
