Yes. Asteroids can enter earth's atmosphere. In such an event the asteroid will probably strike earth's surface.
Some asteroids split into peices and breaking apart as they enter the atmosphere
No, they start breaking down to a small rock, asteroids enter the earths atmosphere frequently.
Meteors are pieces of asteroids or whole asteroids in the earths atmosphere only. Written By, Brainiocity

Both meteoroid's and comets are made out of rock and burn up when getting into earths atmosphere.
they come from earths atmosphere and gases
Asteroids
That depends are they in earths atmosphere and able to fall, or are they in outer space and only able to float?
The asteroid belt, is a "collection" of asteroids circling the Sun in between the orbits of Mars and Jupiter. A collection cannot have an atmosphere. A single asteroid does not have enough mass to "hold" on to an atmosphere.
Asteroids have a constant speed in a vacuum if there isnt anything else affecting it such as gravity or by colliding with other things. If it was to be in the earths atmosphere then the air would cause a resistance and slow it down :) hope this helps
It is a meteorite (meteor).
yes, many objects enter earths atmosphere everyday but are burnt up before they make it to the ground.
