Answer to Question 1

C

Answer to Question 2

The equatorial area is hot because sunlight is concentrated over a smaller surface area. Surface winds of two Hadley cells also converge in this area producing an equatorial low called the intertropical convergence zone (ITCZ). Strong heating in the ITCZ causes surface air to expand and rise. The humid, rising, expanding air loses moisture as rain, some of which contributes to the success of tropical rain forests.


Sinking air, in contrast, is generally arid. World deserts of both hemispheres, dry bands centered around 30 N&S latitudes, mark the intersection of the Hadley and Ferrel cells. Air falls toward Earth's surface in these areas, causing compressional heating. Because evaporation is higher than precipitation in these areas, ocean-surface salinity tends to be highest at these latitudes.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
