Welcome to the Street Prophets Coffee Hour cleverly hidden at the intersection of religion and politics. This is an open thread where we can share our thoughts and comments about the day. Let’s start with a discussion of meteorites.
The Mineral Museum on the campus of Montana Tech in Butte has displays of meteorites. Meteorites are thought to originate in the Asteroid Belt, located between the orbits of Mars and Jupiter. Occasionally, objects from the Asteroid Belt come close enough to get caught in earth’s gravity. When they travel through the earth’s atmosphere they are known as meteors. As they travel through the atmosphere, they are heated to extreme temperatures which causes the outer surface to melt off and produce the thumbprint feature which resembles thumbprints made in soft clay. Meteors which survive the trip through the atmosphere and strike the surface of the earth are known as meteorites.
Nickel-Iron Meteorites
Nickel-iron meteorites are composed of nickel-iron alloys. This means that they are two or three times heavier than a typical rock of comparable size. These are the most frequently found meteorites.
