Answer:
c. Chemical weathering
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>

Answer:
20h
Explanation:
The proper equation would be 20h, as if Andrea reads 20 pages per hour, you simply multiply by the number of hours she's been reading to find the number of pages she's read.
For example, if Andrea was to read for 3 hours, she would have read 60 pages as 20*3 = 60
Hope this helps!
