  • Interesting fact: Plant life could not exist without lightning. Nitrogen, an essential food for plants, comprises 80% of the atmosphere, but in a form that is insoluble and unusable. It's the intense heat of lightning that forces the nitrogen to combine with oxygen in the air, forming nitrogen oxides that are soluble in water and fall to the earth in rain as dilute nitric acid. This reacts with minerals in the ground to become the nitrates on which the plants depend.
    • Insolubility The quality of being inexplicable or insolvable.
    • Insolubility The quality or state of being insoluble or not dissolvable, as in a fluid.
