The asteroid belt does not have a surface as it is not an objects. It is a loose scattering of objects.
Yes, they orbit the sun, a nice balance of centrifugal force and gravity. If they did not move, relative to the sun, the sun's gravity would pull the asteroids into
Yes, the force of gravity is constantly acting upon the asteroid belt. It is in fact thought that this is why the asteroids in the asteroid belt didn't become planets; as the gravitational pull of Jupiter caused, and still causes the asteroids to move about and therefore never form into a larger planet.
Some asteroids are considered associated and are called "groups." Most asteroids are not part of groups but are in a "belt" positioned between Mars and Jupiter. Certain zones of gravitional equilibrium can capture asteroids. These zones are known as LaGrange Points. Jupiter, having the most powerful planetary gravity, has several groups at these points. Two of them, because the individual asteroids in them are named after heroes in the Trojan War, are known as "Trojan asteroids." One group is the "Trojan" group and another is the "Greek" group, even though there's an important Trojan in the Greeks and an important Greek with the Trojans.
The evidence that asteroids have collided with earth before, depends on the surface. The way you can find this if there is unusual shapes in the ground( e.g. really deep ditch, that is too big for a human too dig).
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.

Yes, it is commonly thought the moons originated as asteroids, pulled from the belt by gravity.
No. The asteroid belt is not an object but a region with more asteroids than the rest of the solar system. Asteroids themselves have too little gravity to have atmospheres.
The reason asteroids shoot is because gravity pulls them away from the belt. A other reason that asteroids shoot is because smaller asteroids hit them and send them rorring through the air.
No. The asteroid belt is not an object. It is a region of the solar system where there are more asteroids than in other areas.

asteroids belt
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 ("star like things") better name Planetoids ("planet like things"). Bits of the rocky parts of the early Solar System that didn't get to form into one planet, presumably due to the perturbations of Jupiter's gravity. They lie in a harmonic zone where a planet should be, but the largest of them, Ceres, is only about the size of Texas.
Earth is much more massive than asteroids and comets, and thefore has much stronger gravity, which pulls it into a spherical shape. Most asteroids and comets do not have strong enough gravity to do this.
