Textbook Question
Chapter 52, Problem 52.1CR

Suppose global air circulation suddenly reversed, with moist air ascending at 30° north and south latitude and descending at the equator. At what latitude would you most likely find deserts in this scenario?

Expert Solution & Answer
Check Mark
Summary Introduction

To determine: The latitude in which deserts be found if the global air circulation is reversed.

Introduction:

Latitudes are imaginary lines that pass through the earth surface. They divide the earth horizontally and at equator the latitude is 0 . Global air circulation is the movement of air from high pressure regions to low pressure regions.

Explanation of Solution

The movement of air determines the weather of a particular area. The deserts are mostly found in a region where the dry air is present. Currently the deserts are found in the 30 latitude. If the global air circulation is reversed and the dry air which ascends at 30 , now ascends at 0 latitude then the desert region would be found at the equator instead of 30 north and south of the equator.

Conclusion

If the air circulation is reversed then the deserts will most likely occur at 0° latitude, that is, at the equator instead of 30° north and south latitude.

Considering the human connection to hydrologic changes, how will climate change affect the main components of the cryosphere, and the subsequent effects that will cause changes in drylands?
Areas approximately thirty (30) degrees north and south of the equator are home to many of the world’s deserts.  What happens at these latitudes to cause deserts to form? Group of answer choices a. moist air falls from the upper atmosphere b. mountains block air from the ocean c. dry air rises into the upper atmosphere d. dry air falls from the upper atmosphere e. moist air rises into the upper atmosphere
Deserts are commonly found around the world at 30 degrees latitude north and south of the equator.  Why are these areas so dry? Group of answer choices -there is no ocean at these latitudes -Cool dry air sinks to the ground at these latitudes -rain shadows -the sun is usually directly overhead
