Answer to Question 1

Answer: Tectonic plates are large pieces of Earth's crust that move relative to one another. It is believed that the movements are caused by the fluid convective currents in the mantle which are in turn powered by heat within the Earth's inner core. Three main horizontal plate movements are identified. These are: divergent movement, convergent movements and transform movement.

Divergent plate movements occur when plates are spreading apart. The rates of movement are very slow; typically only a few centimeters per year. Globally, most divergent boundaries are under water. Two the most well-known examples are the Mid-Atlantic ridge and the rift valleys of East Africa

A convergent boundary occurs when plates push together. Material from one plate is slowly forced downward by the collision, back into the mantle. The Himalayas originated, and continue to be formed by the convergence of the Indo-Australian and Eurasian plates.

When two plates neither converge nor diverge, but grind past each other, a transform plate boundary is formed. California's San Andreas Fault is an example of this, because the Pacific plate is moving northwest relative to the North American plate. The boundary between these plates is not a smooth one, and ridges and mountains are built as the two plates grind against one another. The plates bind for long periods and then abruptly slip, causing the earthquakes that frequently strike California.

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.
