Answer to Question 1

Solar energy (short wave) passes through the air without much effect. When it strikes a surface, such as the ground,
it is converted to heat. That heat radiates back into the air as infrared (long wave) energy. Some gasses, such as carbon
dioxide and methane, are very effective at trapping that infrared light and converting it back into heat. When
the air is warmed as a result of gasses converting infrared radiation back into heat, the air warms. The warming of
the air is the greenhouse effect.



Answer to Question 2

The atmosphere is about 78 percent nitrogen gas (N2) and about 21 percent oxygen gas (O2). The remaining
1 percent is made up of mostly argon gas (Ar), carbon dioxide (CO2), water vapor (H2O), and ozone (O3). There
are two reasons that the other gasses are a concern. First, some gasses can be toxic to living things. Excess ozone
near the surface can harm plants as can gasses like sulfur dioxide. Carbon monoxide is very poisonous to animals,
including humans. The other reason is the greenhouse effect.

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.

There used to be a metric calendar, as well as metric clocks. The metric calendar, or "French Republican Calendar" divided the year into 12 months, but each month was divided into three 10-day weeks. Each day had 10 decimal hours. Each hour had 100 decimal minutes. Due to lack of popularity, the metric clocks and calendars were ended in 1795, three years after they had been first marketed.
