The latest thinking on this subject is as follows: Not all small and sundry asteroids can be stopped from hitting the earth. Those asteroids whose paths and trajectory are fairly known along with their periodicity can be nudged from a collision course to earth by sending a rocket or spacecraft. The proximity of the rocket or spacecraft itself is expected to change the trajectory of the asteroid (in a controlled and calculated manner.) In years to come, science may come up with other additions to this basic concept to successfully deviate the asteroid from its collision course to the earth.
No known existing equipment or firm plans are in place at this time for stopping a huge potential Earth strike asteroid from making contact. Ideas being bandied about are nuclear detonations at or near the asteroid, and propulsion system attachment to the asteroid to veer it away from Earth intercept.
There isn't much that can be do now. When asteroids that will impact the Earth are discovered, its probably already too late. Even one year is won't be enough time. However, it would be possible in the near future (up to 200 years) to send up space missiles to destroy smaller asteroids (bigger ones will need stronger weapons to destroy).
We could also possibly use magnetic devices to change the course of the asteroids. However, these wouldn't be invented as quickly as space missiles.
Only an asteroid larger than 10km in diameter would send ash all over the world. There are not many of these. The chance of an asteroid crashing with the Earth is close to 0%, so we are generally quite safe.
The gravitational force of Jupiter pulls in asteroids and comets that might hit earth.
NASA is planning for it.If possible humans will shoot down meteor and make it crash into pieces.

the o zone
The main thing it does is it prevents comets and asteroids from hitting earth by pulling them towards itself with its enormous gravity. Some astronomers also think its gravity changes the paths of objects that would otherwise hit earth.
Hopefully, they burn up on entering our atmosphere, due to friction with the air.
It is possible for comets and asteroids to hit Earth, but they are extremely rare events.
Asteroids orbit the Sun, and some of them can cross the Earth's orbit.
The athmosphere
All the way from forming the moon to pretty lights in the sky.

Small asteroids can be deflected by explosives (ordinary or nuclear) if they are far enough away. The problem is getting the explosives there. Asteroids travel at orbital speeds of thousands of kilometers an hour, and a large rocket would be required to reach the asteroid and match its speed, so that it could rendezvous and detonate. Hitting an asteroid with a head-on shot would be extremely difficult if not impossible, and could result in a shower of smaller pieces hitting the Earth.
Asteroids that occasionally cross the orbit of Earth are known as Near Earth Asteroids. Asteroids that both cross the orbit of the Earth and are large enough to pose a significant threat in the event of an impact are known as Potentially Hazardous Asteroids.
asteroids vary in size from rock size to earth size and bigger.

No. Asteroids can hit anywhere on earth.
Air pressure is a atmospheric pressure. Air pressure creates: 1. Different climate 2. Creation of rain 3. Creation of wind 4. It prevents small asteroids to come to the earth
No, that would be apollo asteroids
