asteriods as they enter the atmoshpere

Because an asteroid is moving at speeds of 6,000 mph and higher it passes the atmoshpere in seconds. When it goes through the atmosphere, it creates a huge amount of air friction causing it to catch fire. The fire gets so hot, that the asteroid can break into smaller pieces. thus not causing as much damage to earth

The gravitational force (or attraction) between any two objects increases as the distance between them decreases. Thus, as an asteroid approaches Earth, the Earth's gravitational pull will increase as it gets nearer.

An asteroids orbit is often in an asteroid belt where as a comet is able to change its course when it approaches a planet. An asteroid can not do this.

Not much should usually happen, though it might depend on the size of the asteroid. The real danger is for the asteroid to actually hit Earth.

it depends on how big the asteroid is... if it is Hugh everyone on earth could die.. if it is small it could kill some people
