Explain how dark soot over the Indian Ocean increases the intensity of regional droughts
What will be an ideal response?.
ANSWER: Dark soot in the cloud of pollutants over the Indian Ocean absorbs heat and warms the upper atmosphere. However, it also reduces heat to the lower atmosphere and cools the surface of the ocean, which reduces evaporation. This in turn increases the intensity of regional droughts because less moisture is available to fall as rain.

The city of Guildhall experienced two earthquakes within a 1-month interval. The first earthquake was magnitude 2; the second earthquake was magnitude 7. How do the speed of the S-waves from the magnitude 2 earthquake compare to the speed of the S-waves from the magnitude 7 earthquake (magnitude 2 compared to 7)?

How do the speed of the S-waves from the magnitude 2 earthquake compare to the speed of the S-waves from the magnitude 7 earthquake (magnitude 2 compared to 7)?
- Magnitude 2 S-waves are faster than magnitude 7 S-waves.
- Magnitude 2 S-waves are slower than magnitude 7 S-waves.
- Magnitude 2 S-waves are the same speed as magnitude 7 S-waves.
As surface air rushes in toward the eye of a hurricane, the air expands and should cool. The main reason the surface air is not cooler around the eye is because
a. the sinking air near the eye warms the air. b. friction with the water adds heat to the air. c. the warm water heats the air. d. sunlight heats the air. e. the spinning motion prevents air from rising or sinking.
