To find the spot located at 40 degrees north latitude and 120 degrees west longitude, you would look at the intersection of the latitude line (40 degrees N) and the longitude line (120 degrees W).
Based on your description:
- 40 degrees north latitude runs through the southern portion of the United States, specifically from California to the Mid-Atlantic States.
- 120 degrees west longitude runs through central Canada and the western portion of the United States around the Rocky Mountains.
Given these coordinates, the point at 40°N, 120°W is likely located in the western part of the United States, near the state of California.
So, you should select the hot spot that is located in North America near the West Coast of the United States.
