Question

How many mainland regions does New Mexico have?And how do you describe them?

Answer 1

New Mexico has 6 regions:  Central, North Central, Northeast, Northwest, Southwest, and Southeast.

Answer 2

This is the website for the United States Geodetic Survey:

And this is the page for New Mexico:

Quatenary

Tertiary

Cretacious

Triasic-Jurasic

Permian

Pennsylvanian

Mississippian

Ordovician

Cambrian

Pre-Cambrian

So I would say there are ten, based on the ages of the rocks found at the surface in different parts of New Mexico.
