Answer to Question 1

As sand is dropped in front of the migrating dune on the slip face, it forms layers at an angle in the prevailing wind direction. Over time and dune migration, these layers pile up, but their defined inclination remains and is called cross bedding. This sedimentary structure is a unique characteristic that can be used to tell the geologic story from the rock record.

Answer to Question 2

Loess is wind-blown silt carried in suspension that forms extensive blankets when deposited. Sand dunes are ridges and mounds of sand formed by wind. Silt is typically carried much farther distances than sand.

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.
