The great deserts and associated arid areas of world mostly lie along the western sides of the continents at about how many degrees north or south latitude?

Check this map.

The best answer seems to be 30 degrees.

The choices are:

-90 degrees
-15 degrees
-60 degrees
-0 degrees
-30 degrees

Is that certain, Ms. Sue?

You can see the map. What do you think.

Well, it seems to inch more near the 60 degrees, but I will take your word for it.

The key word is "mostly." You may be right about 60, but I still think 30 is a better answer for this question.

What does your text say?

Also -- the question specifies arid areas on the western sides of the continents.

You're right! I just entered it into the multiple choice box and it told me I was correct. Thank-you, thank-you, thank-you!

You're welcome.

I can think of several specific numbers of degrees.

What are your choices?
