Most of the meteorites that we collect on Earth come from the main belt of asteroids located between Mars and Jupiter. They were ejected from their asteroidal “parent body” after a collision, were injected into a new orbit, and they finally felt onto the Earth.Most of the meteorites that we collect on Earth come from the main belt of asteroids located between Mars and Jupiter.

What is the most likely source of meteorites quizlet?
What is the most likely source of meteoroids? Meteoroids come from asteroids that are broken apart by impacts with other asteroids.
Where are meteorites most likely to be found?
Nearly all meteorites are found in deserts. (Yes, Antarctica is a desert because the annual precipitation rate is very low.) Deserts are places that accumulate meteorites over thousands of years and then nothing much happens to the meteorite.
How are most meteorites found?
Most meteorites found on Earth come from shattered asteroids, although some come from Mars or the Moon.
What is the major source of meteor shower meteoroids?
Meteor showers occur when dust or particles from asteroids or comets enter Earth's atmosphere at very high speed. When they hit the atmosphere, meteors rub against air particles and create friction, heating the meteors. The heat vaporizes most meteors, creating what we call shooting stars.
What is a meteorite quizlet?
What is a meteorite? An extraterrestrial body which has fallen to Earth.
What types of meteorites are there?
There are three main types of meteorites:
- iron meteorites: which are almost completely made of metal.
- stony-iron meteorites: which have nearly equal amounts of metal and silicate crystals.
- stony meteorites: which mostly have silicate minerals.
Why are most meteorites found in Antarctica?
Although meteorites frequently fall all over the world, they get concentrated in special places in Antarctica, making them easier to find. As meteorites strike glaciers, they get buried in the ice and accumulate over thousands of years. As the glaciers slowly flow, the meteorites are carried with them.
How rare is it to find a meteorite?
The chance of finding a meteorite is exceedingly small. Since 1900, about 1800 meteorites have been found in North America. That is about 15 per year. About two thirds of meteorites found in the United States have been found in arid regions of California, Nevada, Arizona, New Mexico, Texas, and Kansas.
What are the 3 main sources of meteoroids?
What three sources do meteoroids originate from?
- interplanetary debris that was not gravitationally swept up by the planets during the formation of the solar system,
- material from the asteroid belt, or.
- the solid remains of comets that once traveled near Earth's orbit.
