Question

The image shows isotherms on a map.

A Temperature Map of the United notes shows isotherms.

What temperature pattern do the isotherms show?

Temperatures increase from south to north.
There is a zone of low temperatures in the Southwest.
There is a zone of high temperatures in the center of the country.
Temperatures increase from the center of the country toward the Southeast.

Answer 1

I don’t have the map image here — could you upload it or describe the isotherm labels (the temperature numbers) and their general shape?

If you want to check it yourself, here’s how to pick the correct option:
- Find the temperature numbers on the isotherms and follow the direction in which they get larger. That direction is where temperature increases.
- Option 1 (increase from south to north): the numbers should be higher in the north than in the south.
- Option 2 (low temperatures in the Southwest): the smallest temperature values should be clustered in the Southwest region.
- Option 3 (high temperatures in the center): the largest temperature values should be centered in the middle of the country.
- Option 4 (increase from the center toward the Southeast): numbers should rise as you move from the center toward the Southeast.

Upload the map or tell me a few isotherm numbers and where they are, and I’ll pick the correct choice.
