A total solar eclipse occurs when the moon completely blocks the sun from part of the Earth, essentially turning day into night.
A total lunar eclipse occurs when Earth blocks all sunlight from reaching the moon save for the small amount that is refracted through the atmosphere.
In a total eclipse, the surface of one celestial body is obscured by the surface of another.
Yes, these are called partial eclipses.
yes they do
No. About 50% of all lunar eclipses are total; the remainder are partial or penumbral.
There was 2 lunar eclipses in 2008.

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.
There are two main types of eclipses: solar and lunar. Lunar eclipses occur every 6 months. Solar eclipses occur 2-5 times per year. Eclipses can be partial or total. Partial eclipse covers only part of the sun or moon, while total covers the full entity.
Partial 35.3%Annular 33.2%Total 26.7%Hybrid 4.8% As you can see from the table above, partial eclipses are most common, followed by annular eclipses. Total solar eclipses are barely more than one-quarter of the total. Total eclipses occur when the Moon is close enough to the Earth for the umbra, the cone of total shadow, to hit the Earth. Annular eclipses occur when the Moon is so far away that the umbra does not reach all the way to the Earth. "Hybrid" eclipses occur when the Moon crosses the dividing line between total and annular DURING the eclipse, so that the eclipse begins as annular and changes to total, or vice versa, during the eclipse.
In general, there are two lunar eclipses and two solar eclipses each year. On average, about half are total and half are partial, so you can expect, over a span of years, to see one total lunar eclipse every other year. There are sometimes cycles of eclipses. In 2014-2015, there will be four sequential total lunar eclipses, with no partial eclipses in between; this cycle is called a "tetrad" and it isn't all that unusual. There will be eight such tetrads in the 21st century; this will be the second tetrad of the century.
There were no total solar eclipses during 2007. There was one total lunar eclipse, one partial lunar eclipse, and two partial solar eclipses.
