Comets have tails as they consist mainly of ices, which vapourise when the comet approaches the sun, taking some of the dust off with it. Meteoroids are mainly made of rock, their surfaces tend to stay intact, so they don't have tails.
Sort of. Comets don't have to break up to spawn meteoroids since the solar wind knocks little bits off of them, which become the "tails." "Dust cloud" actually means something different to astronomers, namely the bits of stuff out of which stars (and planets) form. Say rather "cometary dust trails."
Meteoroids primarily originate from two sources: asteroids and comets. Most meteoroids are fragments of asteroids, particularly from the asteroid belt located between Mars and Jupiter. Comets, when they approach the Sun, shed debris that can also become meteoroids. Additionally, some meteoroids can originate from the Moon or Mars, where impacts have ejected material into space.
Meteoroids are typically composed of rock and metal, such as iron and nickel. Ice can also be present in some meteoroids, particularly those originating from comet fragments.
All planets, both with and without atmospheres, encounter meteoroids. If the planet has an atmosphere then those meteoroids will burn up long before reaching the surface. Those without atmospheres do not have such protection and so the meteoroids strike the surface directly.

They are shooting stars
Meteoroids are big lumps of rock in space.
Meteoroids burn up in the Mesosphere. Even though the Mesosphere is the coldest layer, the meteoroids burn up from getting too cold. Meteoroids are also more commonly known as "shooting stars".

The three types of small bodies in the solar system are asteroids, comets, and meteoroids. Asteroids are rocky objects found mostly in the asteroid belt between Mars and Jupiter, comets are icy bodies with tails that form when they approach the sun, and meteoroids are small rocky or metallic fragments that travel through space.

Meteoroids are small, solid, extraterrestrial bodies that hits the earth's atmosphere.

We know that there are small meteoroids and dust in space because meteorites (meteoroids that survive the atmosphere and land on Earth) exist, and also because we can see meteoroids as meteors (the light coming from a meteoroid burning up in the atmosphere) in the sky.
