There are between two and five every year. However, each solar eclipse is visible from only a limited geographical area; so at any given location on earth you typically have to wait several years between eclipses.
Because for any given point on Earth, lunar eclipses are visible more often than solar eclipses.
About twice a year.
On earth there are 2 eclipses, Lunar and Solar eclipses
A Solar Eclips Is Natural It Cant be Prevented, but they dont come as often as you would think.. so the only way to prevent one was to move the orbit of the moon
usually around a few hundred years.
There are generally two solar eclipses per year, 6 months apart. However, one spot on the Earth will see eclipses only about every 60 years.
Both solar and lunar eclipses generally occur 2 times a year. Some years you will have fewer, or more. For example, there will be NO solar eclipses at all during 2011! The maximum possible number of solar or lunar eclipses per year is five.
Lunar eclipses and solar eclipses happen EQUALLY often; about two of each kind per year. However, solar eclipses are visible only across a small path on the Earth, while lunar eclipses are visible from the entire nighttime hemisphere of the planet.
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.
'C' (the missing one) is the correct choice.
About one or two solar eclipses per year, and one or two lunar (Moon) eclipses per year, on average. Go to NASA.com and search it. there will be a map with the spots of eclipses and time/year.
