Question

suggest why meteriods are such different sizes​

Answer 1

Explanation:

Most meteoroids that cause meteors are about the size of a grain of sand, i.e. they are usually millimeter-sized or smaller. Meteoroid sizes can be calculated from their mass and density which, in turn, can be estimated from the observed meteor trajectory in the upper atmosphere.

Answer 2

Answer is:-

Most meteorites date from the oldest times in the solar system and are by far the oldest material available on the planet. Despite their age, they are fairly vulnerable to terrestrial environment: water, salt, and oxygen attack the meteorites as soon they reach the ground.

So, they have such different size.
