Question: Most meteorites are found in Antarctica and where else?
Correct Answer They are easy to spot in the desert or ice. Over 24,000 meteorites of notable size are known to have landed on Earth. A Martian meteorite can fetch about $500 a gram. Most other space rocks are about $2 a gram.
Question: In what country must you turn over any meteor finds?
Correct Answer The Meteoritical Society demands that 20% or 20 grams (whichever is smaller) be donated for research, no matter what country it is found in. This is hard to enforce as they have no legal authority. However, the National Heritage Law in South Africa requires that all of the meteors found in South Africa be turned over to the authorities.
Question: It has been estimated that a meteorite does what once every 180 years?
Correct Answer The study was done in 1985 by "Nature". That averages out to .0055 times a year. The last one in the 20th century struck a woman in the southern part of the United States. The meteorite was about eight pounds.
Question: The International Space Station has protection from meteors. What is it made of?
Correct Answer That's right, the same stuff used for bullet-proof vests. It is a foot thick. About 100,000 meteors should strike the ISS in its 20 year lifetime. While iron is a common part of meteors. most meteors are composed of chondite. Chondite is similar in composition to the mantles and crusts of the terrestrial planets.
Question: The most famous meteor shower is the Perseids. What is its other name?
Correct Answer This spectacular shower is named after a martyr in early Rome. He was burned on an open stove in 258 AD. Another famous meteor shower, the Leonids, inspired this section of "The Rime of the Ancient Mariner", by Samuel Taylor Coleridge:
The upper air burst into life!
And a hundred fire-flags sheen,
To and fro they were hurried about!
And to and fro, and in and out,
The wan stars danced between
And the coming wind did roar more loud,
And the sails did sigh like sedge;
And the rain poured down from one black cloud;
The Moon was at its edge...
Question: Which of the "rare" gases is the most common in the atmosphere?
Correct Answer Argon makes up a little less than 1% of the atmosphere. Helium is by far the most common of the rare gases in the universe- only hydrogen is more common. However, it is found in lower concentrations than argon in Earth's atmosphere, because atmospheric helium easily escapes into space.
