Question 1

What time span is required to produce most mineral deposits?
◦ tens of thousands to millions of years
◦ 1-100 years, or about a human life span
◦ billions of years
◦ We have no way of knowing this, but most were formed at the same time as Earth.

Question 2

Below is a picture of the enormous Bingham Canyon copper mine in Utah. What is the reason that the mine is so large?



◦ The mine is the only location on Earth where copper is found, so the hole needs to be large.
◦ It is unknown if any copper underlies this deposit, so miners must continue to dig to find it.
◦ Copper is economically valuable even in small quantities, so it is considered to be worth creating a large hole to extract as much as possible.
◦ Copper exists in abundant quantities, so miners are trying to extract as much as possible.

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.
