Describe the process of expansion.

Expansion's process is a simple one. Gain something more. If you wanted to expand your land you would go and gain more land therefore expanding. If you wanted to expand a town you would build more things therefore gaining more buildings.

I hope this helped. Have a great day!

Currently, as of february 2016, an american traveling in france would be by the exchange rate. the weakness of the euro and the strength of the us dollar means that items in france cost less to an american than they otherwise would. of course, if this trend reverses and the us dollar weakens and the euro strengthens, such as was happening in early 2008, an american traveling in france would have an adverse experience because items would cost relatively more.
