Explanation:
One of the famous landmarks in New York City is "The Statue of Liberty." It was built in<em> 1886</em> as a gift to the Americans from France.
The statue is covered with<em> copper sheets</em>, thus, it used to have a brown color. However, over time, the color turned into greenish-blue. This is because<u> the copper sheets underwent chemical weathering</u>. Such process occurred as a result of the reaction of copper with Oxygen in the air and with water. It produced<em> "copper carbonate,"</em> which is<em> greenish-blue</em> in color. Such color was noticeable in<em> </em>1900<em>, </em>but it covered the entire statue in <em>1906.</em>
