Answer:
The correct answer to the question is that although scientists have studied meteorites and know that there are two major types, they are still unsure of the exact location from which they came.
Explanation:
Meteorites, Meteors, and Meteoroids, are types of space rocks, that have been classified by science according to where they are at a certain point in time. A Meteoroid, is the name given to the space rock that is still outside of the Earth´s atmosphere, and it can be as small as sand grains, or as big as an asteorid. A Meteor, is a piece of a Meteoroid that enters the atmosphere, and while most are burned against the planet´s surface, some make it in and can be found. When the piece makes into Earth, and hits the ground, they are known as Meteorites. Scientists know exactly the origin of these rocks (planets, stars, asteroids, moons) and they can calculate their general locations. But what they still cannot predict with certainty is the exact location from which a Meteoroid, or asteroid, will come from.
