Which region is named for a major landform

I don’t know this one

Many regions are named for major land forms. A few examples include:
The Great Lakes
The Great Plains
The Great Basin
Provence-Alpes-Côte d'Azur (roughly translated as "Region of the Alps near the [sea] coast")
Appalachia
Yucatán Peninsula
Gulf Coast
Hawke's Bay
Ohio Valley
Kilimanjaro Region
Foothills of the San Gabriel Valley

To sum it up you’ll get in a lot of trouble and even some legal action can be taken

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.
