Answer to Question 1

Dams change flow, trapping much of the sediment behind the dam and leading to erosion downstream of the dam. Loss of vegetation can lead to greater runoff and erosion of stream banks (and silting of rivers). Run off increases in hardscape areas such as cities.

Answer to Question 2

Terraces are step-and-bench landforms alongside and above a river channel. Soils on the terrace top lie on bedload deposits, revealing the presence of an ancient channel that was higher in elevation than its current position.

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.

Hypertension is a silent killer because it is deadly and has no significant early symptoms. The danger from hypertension is the extra load on the heart, which can lead to hypertensive heart disease and kidney damage.
