Sometimes they do; that's what a "meteor shower" is. The point is that all of the rocks and dust given off by a comet, and the head of the comet too, travel the way gravity and the light pressure of the Sun force them to.
The head of the comet is freely falling towards the Sun. (if a comet gets close enough to a planet, the gravity of the planet becomes significant, and sometimes the comet will collide with the planet; look at Shoemaker-Levy 9, which hit Jupiter in 1994.) As the heat of the Sun begins to melt the ices of the comet, gas and dust escape from the comet. Because the gas molecules and dust particles are very light, the pressure of the Sun's light pushes them away from the comet; this forms the "tail" of the comet.
Over the course of thousands of orbits, the gas and dust spreads out to fill in much of the orbit of the comet. Where the Earth's orbit intersects the comet's orbit, we see annual meteor showers.

Meteors are rocks from outer space that?
Meteors are rocks from outer space that strike the Earth's atmosphere and are heated to incandescence (glowing heat) by friction. Most are completely vaporized, but some do fall to Earth.
What does a planet's atmosphere do?
it keeps us alive. it holds in are air. it blocks the suns harmfull rays. it breaks up space rocks when the fall twards earth.
Why dont you fall down from earth while it rotate?
Sir Issac Newton is rolling in his grave... The answer is Gravity, essentially, everything is pulled toward the center of the earth. Gravity causes things to fall and gives everything on earth weight
How objects fall on Earth and on the moon?
Objects fall faster to the earth, then compared to the moon, it is due to the different power of gravity on the the earth and moon.
Will the International Space Station fall to the Earth?
it will fall in 20 year till it will fall.
How do meteors hit earth?
There's nothing special about it; they are just falling rocks. Of course, they are rocks that fall FROM SPACE, and the Earth is just sort of "in the way" as the rocks are falling around the Sun.
What cuases rock fall?
Rocks fall because of gravity. Gravity is the force that brings things back to earth. Rocks on a slope, mountain, hill, etc. fall or roll down the hill with gravity. Also, mudslides and other things can push rocks down.
What space objects are made of chunks of rock?
Comets and asteroids are made of chunks of space rocks and dust. Meteorites are space rocks that are captured by the earth's gravity and fall to earth.
Meteors are rocks from outer space that?
Meteors are rocks from outer space that strike the Earth's atmosphere and are heated to incandescence (glowing heat) by friction. Most are completely vaporized, but some do fall to Earth.
Describe the dirction in which soil and rocks particles to fall?
Things fall in the direction that we call "down". BTW, "down" may point in different "absolute" directions.
What invisible force holds you onto the earth so that you dont simply fall?
Gravity, obviously.
What causes the soil and rocks particles fall?
When the ground thaws, the force of gravity causes the soil and rock particles to fall back down. But they fall vertically, toward the center of Earth. The result is movement downhill.
What type of rocks fall off mountains?
rocks
Why does rocks from fall from the sky?
When a volcano erupts it releases liquid magma into the air and as it falls to the earth it cools down and becomes solid.
Can you fall of the earth?
No, you can not fall of the Earth.
Why doesnt the earth get bigger if rocks are forming?
The earth does get bigger! Every time a meteorite hits the earth, or even if it burns up in the atmosphere, the "mass" of that meteorite adds to the mass of the earth. Simply put, mass is weigh and material. Rocks however don't add too much mass to the earth. Rocks are formed from lava (igneous rocks) or from part of the earth's crust (sedimentary rocks). They don't add any weight to the earth because when the weight of the rocks is added to the weight of the rest of the earth, the total weight is the same as it was before the rocks were formed. I believe your question has more to do with size. In other words, if more and more rocks are being formed on the outside of the earth, why doesn't the earth get bigger? The answer is similar. The rocks that are formed on the outside of the earth come from the inside of the earth. Therefore, when rocks are formed on the outside of the earth, they leave empty spaces inside the earth. In reality, the"empty space inside" that I mentioned could be very small and is not deep in the earth's crust. The empty spaces won't make the earth fall in on itself all of the time. If water from under the earth's crust are carried away, however, sinkholes can form. Much more mass needs to be added to the earth until the earth can become noticeably bigger
What is a Rock fall?
a rock fall is when rocks fall off cliffs or other things it is mostly for Stonehenge and Stonehenge rocks fell because of the angry birds.
