Aluminum forms one-twelfth of the Earth's crust.

An elementary rule of mushroom collecting is never to place edible and poisonous specimens together. The slightest touch may contaminate.
Hurricanes often cause between 3 to 6 inches of rain to fall in a short period. In 1921, a hurricane deposited 23 inches on Texas in a day.
Hurricanes, cyclones, and typhoons spin counter-clockwise north of the equator, and clockwise south of the equator. This is known as the Coriolis Effect.
Ice-fog — containing minute ice crystals — shines and glitters in sunlight. It is rather colorfully known as 'diamond dust.' Ice fogs frequently occur around Alaska, where temperatures may drop to -40 degrees Fahrenheit in winter.
If there would be no greenhouse gases in the atmosphere, the average temperature on Earth would be 5 degrees Fahrenheit, instead of the present average of 57 degrees Fahrenheit.
If all the Earth's atmosphere was moving at the speed of a light breeze, its total energy would be equal to that generated by a large hydroelectric dam operating continuously for 7,000 years.
If all the water in the atmosphere at any one time was to fall as rain, it would cover the entire Earth's surface to a depth of 1 inch.
If all the water vapor in the Earth's atmosphere were condensed to liquid water at the same time, there would be enough water to cover the United States (including Hawaii and Alaska) with a 25-foot-deep layer of water.
If harnessed, the energy liberated by an average hurricane could supply the electrical energy used in the U.S. during half a year.
If the amount of carbon dioxide in the atmosphere was doubled, the average temperature of the Earth would rise by 4 degrees Fahrenheit. Many forecasters expect carbon dioxide to double by the year 2025. The world would then be warmer than at any time in the last 100,000 years.
If the Earth's axis was not tilted, there would be 12-hour days everywhere, and no seasons. At the poles, the sun would always be on the horizon.
An estimated 50 percent of U.S. landfill space is taken up by discarded packaging.
