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?
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
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
If the air circulation is reversed then the deserts will most likely occur at

- Which of the following statements about atmospheric carbon dioxide levels is correct? For about 800,000 years prior to human influence it varied between 180 and 300 ppm and is now above 410 ppm. For about 800,000 years prior to human influence it never exceeded 200 ppm. Its rate of increase in the past century is greater than any seen in the ice core record. Both 1 & 3arrow_forwardQuestion:- Which of the following would be a good example of a microclimate? The cool humid air that escapes from an opening to a cave creates small region in which the surrounding temperatures are not as extreme across the year as they are just a few feet away. The weather on north of the Himalayan Mountains tends to be different than the weather south of it. The Hurricanes in the Golf of Mexico tend to be stronger than the ones in the Atlantic Ocean east of Florida all but one of the above none of the abovearrow_forwardit is not tropospherearrow_forward
- Most deserts are present at around 30o latitute N and S because...a. The Hadley cells in the Summer drop hot dry air at those latitudes Xb. The Hadley cells in the Spring and Fall drop hot dry air at those latitudesc. They are zones of high pressure with high relative humidityd. They are zones of low pressure with low relative humidity A is wrongarrow_forwardIn a Hadley circulation cell at the Equator: Group of answer choices A. air at the Earth’s surface is warmed by the upper atmosphere, becomes turbulent, and causes hurricanes. B. air is warmed by solar radiation, causing it to sink and become more dense. C. air and water vapor are warmed by solar radiation, causing them rise, cool, and release precipitation. D. air is constantly being pushed downward towards the Earth’s surface by new air coming in from 30ON and 30OS. E. solar radiation and high winds dry out the land.arrow_forwardWhat weather conditions are typically associated with the Intertropical Convergence Zone (ITCZ)? Group of answer choices Clear skies and dry conditions Extreme heat and drought High winds and turbulent seas Abundant rainfall and thunderstormsarrow_forward

Elevation: the higher the elevation, the the temperatures b. Distance to water/Nearness to centers of large landmasses: oceans tend to climates while centers of large landmasses have large in temperatures c. Latitude: the higher the latitude, the the temperatures. solar radiation and releasing water d. Vegetation: moderates climate by vapor by e. Global wind: distribute and around Earth f.

One useful data set comes from deep core samples of Antarctic ice. The oldest ice core that has been fully analyzed dates back a bit more than 400,000 years. Air bubbles trapped in the ice provide information about the gas content in Earth's atmosphere at the time the ice formed. Combining ice core data with more recent direct measurements of atmospheric carbon dioxideas in FIGURE 46.20can help scientists put current changes in the atmospheric carbon dioxide into historical perspective. FIGURE 46.20 Changes in atmospheric carbon dioxide levels (in parts per million). Direct measurements began in 1980. Earlier data are based on ice cores. The industrial revolution occurred around 1800. What was the trend in carbon dioxide level in the 800 years prior to this event? What about in the 175 years after it?arrow_forward
