Answer to Question 1

ANSWER: Normal faults involve motion at a divergent boundary where rock above the fault slips down and over the rocks beneath the fault.
Reverse faults involve motion of rock on the upper side of a fault up and over rock beneath the fault.
Strike-slip faults involve motion at a transform boundary and involve horizontal motion parallel to the fault.
Thrust faults are similar to reverse faults, but the fault surface is more gently inclined. Blind thrust faults involve motion that does not reach the surface.

Answer to Question 2

ANSWER: Stress exists along a fault as a result of plate motion.
Strain causes rock to deform in the direction of plate motion.
Rupture is caused by brittle failure of the rock.
Rebound brings rock to an undeformed state.

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.
