How did they put the statue of liberty in the middle of the ocean?
It isn't in the middle of the ocean, it stands on an island which was originally called Bedloe's Island, but which is now known as Liberty Island.
The Statue of Liberty was constructed in France, then disassembled and crated for shipment across the Atlantic Ocean around January of 1885. The statue arrived in New York in June of 1885. There was some difficulties in funding the pedestal, which led to a delayed re-assembly of the statue. After the completion of the statue's construction, a dedication ceremony was held on October 28, 1886.
It wasn't built in New York. It was actually shipped there in pieces from Paris. That's why it's green: it's made of copper, but the salt from the ocean while it was being shipped turned it from brown to green. It was put in New York because that is where most of the immigrants landed when they came over from Europe and the Statue of Liberty became symbolic of America and its acceptance of immigrants.
When France took the US Statue of Liberty for repair how did they bring it back and what did they put inside of that?
The picture of Miss Liberty on the coin is similar to the image used on the Statue of Liberty but the coins were first issued 8 years before the Statue of Liberty was put up - 1878 vs. 1886. They're normally called Morgan dollars after their designer, George T. Morgan. There's more information at the Related Question.
The Base is Concrete, the frame is steel, and the outer covering is copper, which is only 3/32nds of an inch thick. First, the construction of the statue began in France in 1875, the title of the statue: 'Liberty Enlightening the World' It was presented to the American people on July 4th 1884. It was then dismantled and shipped to the United States. I hope this helps
