Geography: Europe has no deserts. There are no active volcanoes in Australia. The largest gorge is the Grand Canyon at 217 miles long (the distance from Paris to London), 4-18 miles wide, and one mile deep. The deepest gorge is Hells Canyon in Snake River, Idaho, at 7,900 feet deep. The three longest rivers in the world are all around 4,000 feet long. The largest European country is Denmark. The latitude of most of Europe would find most of it in Canada. Rome is approxomately where New York is. Were it not for the Gulf Stream ocean current most of Europe would be much colder than it is and many parts largely uninhabitable. America and Russia are only two miles apart.
