What characteristic distinguishes a meteor right from a terrestrial rock quizlet?

What characteristic distinguishes a meteorite from a terrestrial rock? 1. Meteorites contain rare elements, such as iridium, that terrestrial rocks do not.

How does the appearance of a meteorite differ from a terrestrial rock quizlet?

How can we distinguish a meteorite from a terrestrial rock? Dark pitted crust, some have high metal content, enough to attract a magnet hanging on a string. They contain iridium that are rare in Earth rocks. Distinguish between primitive meteorites and processed meteorites in terms of both composition and origin.

What describes a meteorite?

A meteorite is a fragment of spatial matter that falls to the surface of a planet. Most meteorites that fall to Earth come from the Asteroid Belt. Watch as a meteorite travels to Earth, causes an explosion, and creates an impact crater.

Why isn’t there a planet where the asteroids are?

So why doesn’t the asteroid belt condense and form a planet? First of all, there’s not enough total mass in the belt to form a planet. Second, the belt is too close to Jupiter. The belt contains only about 4 percent of the Moon’s mass in asteroids — not enough to form a planet-sized body.

How can primitive meteorites be distinguished from processed meteorites quizlet?

Primitive meteorites are remnants of birth of solar system containing rock and metal flakes. Processed meteorites are fragments of asteroids that can be made of metal or iron. Processed are younger than primitive and are pieces of asteroids that underwent differentiation.

How does Pluto’s orbit differ from Neptune’s orbit?

How does Pluto’s orbit differ from Neptune’s orbit? It is more elliptical. It is tilted more, relative to the plane of the solar system. Pluto and Neptune are locked in a 3:2 orbital resonance that keeps them permanently separated.

How can primitive meteorites be distinguished from processed meteorites?

SUMMARY: Primitive meteorites are remnants of the solar nebula, containing intermixed rock and metal flakes. Processed meteorites are fragments of larger asteroids and therefore can be metallic like a planet’s core or rocky like its mantle or crust.

Why are so many meteorites found in Antarctica quizlet?

Why are most meteorites found in Antarctica? a) Meteorites are dark and easy to spot against the ice in Antarctica. quickly refrozen by the cold temperatures of Antarctica. are more likely to survive atmospheric entry near the poles.

What is the composition of a meteorite?

Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals; iron meteorites that are largely composed of metallic iron-nickel; and, stony-iron meteorites that contain large amounts of both metallic and rocky material.

What does an iron meteorite look like?

Iron is heavy and most meteorites feel much heavier in the hand than an ordinary earth rock should. A softball-sized iron meteorite will likely weigh five or six pounds, making it seem unnaturally dense. Imagine holding a steel ball bearing as big as a grapefruit and you’ll get the idea.

What are the different types of meteorites?

Meteorites are divided into three basic groups: irons, stones, and stony-irons. Practically all meteorites contain a significant amount of extraterrestrial iron and nickel, so the first step in identifying a possible meteorite is the magnet test.

What happens when a meteoroid enters the Earth’s atmosphere?

When a meteoroid (a potential meteorite) streaks through our atmosphere, tremendous heat is generated by atmospheric pressure. The surface of the rock melts and the air around it incandesces. As a result of this brief but intense heating, the surface burns and forms a thin, dark rind called fusion crust.

What is the oldest known meteorite in the world?

Iron meteorite – Campo del Cielo: This beautiful 654.9-gram Campo del Cielo iron meteorite was found in Chaco Province, Argentina. It is one of the world’s oldest-known meteorites and was first discovered by the Spanish in 1576. This example displays excellent regmaglypts (thumbprints), as well as a rare natural hole.
