This is why most glaciers are found either in mountainous areas or the polar regions. However, snow line occurs at different altitudes: in Washington State the snow line is around 1,600 meters (5,500 feet), while in Africa it is over 5,100 meters (16,732 feet), and in Antarctica it is at sea level.
Ninety-five percent of all beer and soft drink cans in the United States are made of aluminum. American can makers produce about 100 billion aluminum beverage cans a year, equivalent to one can per American per day. While almost all food cans are made of steel, aluminum's unique properties make it ideal for holding carbonated beverages. The typical aluminum can weighs less than half an ounce, yet its thin walls withstand more than 90 pounds of pressure per square inch exerted by the carbon dioxide in beer and soft drinks.
Because so many of them are recycled, aluminum cans account for less than 1% of the total U.S. waste stream, according to EPA estimates. An aluminum can that is thrown away will still be a can 500 years from now! There is no limit to the amount of times an aluminum can be recycled. We use over 80,000,000,000 aluminum soda cans every year. At one time, aluminum was more valuable than gold! A 60-watt light bulb can be run for over a day on the amount of energy saved by recycling 1 pound of steel. In one year in the United States, the recycling of steel saves enough energy to heat and light 18,000,000 homes!
