A large impact would send shock waves throughout the Earth, causing earthquakes and possibly stimulating volcanism. In addition, the material thrown into the atmosphere would block out the sun's light, reducing photosynthesis.

The effects on Earth will vary depending on the size and makeup of the asteroid and where it hits. Asteroid strikes have led to minor and major extinction events due to environmental impacts.

What is the percentage of an asteroid hitting earth in the next 100 years?

How can you stop an asteroid from hitting earth?

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.

What effects did an aseroid have on earth?

The Asteroid would be slowly sucked in my Earth's gravitational forces. If it is traveling at a high speed it could plummet towards earth. This may or may not be fatal to the Earth's population. I could quite possibly dislodge enough dust into the atmosphere to be fatal to all beings on the Planet. However if the asteroid is not travelling at a high speed it would orbit around the earth until disturbed. Hope this helps.

If a asteroid hit the world what would the effects be?

The effects would depend on the size of the asteroid, but even if the asteroid was the size of a small house the effects would be devastating. First of all those who live in the area of impact would die in instant destruction. if the asteroid hit water huge tidal waves would be created flooding most of the world, the waves could be up to 3 miles tall maby even taller depending on the size of the asteroid. the sun would also be blackend out because dust would be spewn up into the atmosphere which would stop heat from reaching the planet causeing global cooling
