In that case, a Solar Eclipse occurs. It can be a partial or total eclipse depending on the positions at the time of the eclipse. In total Solar Eclipses, the sun is completely blocked out for a short time in some parts of the world. Likewise, Earth's shadow falling on the Moon is known as a lunar eclipse.
During the 100 years of the 20th Century (1901 - 2000), there were 228 solar eclipses and 13 times lunar eclipses.
About two per year, since the Moon formed. So, around 4000 solar eclipses (and 4000 lunar eclipses) since the year 1. You can check the list of all eclipses since the year 2000 BC on the NASA Eclipse Web Page at the link below.
Lunar and solar eclipses can occur within a few weeks of each other or up to two weeks apart. This is because they are both tied to the cycles of the Moon, but the specific type and timing of each eclipse depend on various factors, resulting in variable separations between lunar and solar eclipses.

The 2009 solar eclipse was a total solar eclipse, which occurs roughly every 18 months somewhere on Earth. However, the next total solar eclipse visible from the same location typically takes much longer, often hundreds of years.

There are solar eclipses every year, and nearly every country has seen one at one point or another, so it is difficult to answer your question. There are many types of eclipses, from ones where only part of the sun is covered, known as a partial eclipse, to ones where the entire sun is covered, known as a total eclipse. A total solar eclipse happens about once every 18 months somewhere in the world. When a total eclipse does occur many countries will see it, and many other countries experience a partial eclipse. A total eclipse in the same place occurs on average about once in every 370 years.
The NASA Eclipse Web Site has a "Solar Eclipse Explorer" page that will allow you to calculate all the eclipses visible from any location from the year 1500BC to 3000 AD. It is at http://eclipse.gsfc.nasa.gov/JLEX/JLEX-index.html. You will need to select a large city that you are interested in or enter the latitude and longitude of your location. I see there that Lagos, Nigeria last experienced a total solar eclipse on February 21, 2008 and will next experience a total solar eclipse on December 21, 2010.
It depends upon where the solar eclipse will occur and when. Australia has had many recent total solar eclipses that have been quite spectacular. It seems that Australia and New Zealand had many solar eclipses in 2012.
3 to 7 minutes.
A solar eclipse is a fairly quick event - from beginning to end is never more than a few hours. The total part of a solar eclipse at one location is never more than 7.5 minutes; the partial phases of the eclipse before and after take the remainder of the time.
a solar eclipse happens about every 6000 days, way more than a year.
On average there are as many solar eclipses as there are lunar ones. But each lunar eclipse can be seen from half the Earth, while a solar eclipse can only be seen from a relatively small strip of the Earth's surface. So in any one place it seems that solar eclipses are rare.
The first solar eclipse of 2011 was on the 4th January.
The path of totality of a solar eclipse is fairly narrow, and the Earth is 3/4 oceans. For any specific spot on the Earth, there may not be any total solar eclipses for hundreds of years.
