Answer to Question 1

I would water the road on busy days because the moisture causes cohesion of the dust grains. The cohesive grains are not as easily picked up by the wind as are dry grains.

Answer to Question 2

The southwestern Sahara is at a more southerly latitude than the southeastern United States, and is in a zone of prevailing easterly winds. These winds transport Sahara dust across the Atlantic Ocean and into the Caribbean Sea. Summer heating over the southeastern U.S. lowers surface air pressure, which produces a seasonal wind from the south that draws in the dusty air from the Caribbean.

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
