Asteroids, even very large ones, actually come close to earth regularly and cause no harm and no effect on life on earth. The concern would be a large asteroid crashing into the earth.

If the meteor was large enough it might significantly affect the environment as to make life difficult. It would have to be extremenly large (moon size) to destroy the earth. However no asteroids of this size exist in our solar system.


Ozone hole affects life. It causes the fatal UV to enter the earth.


The Jupiter helps to divert the path of asteroids which would have otherwise smashed into the Earth and end Life as we know it.


how does what effect life on earth?


It might affect the tide because our moon controls that.


it can affect life on earth by it forming a part of material universe, esp. outside of the earth


They generally have no effects on life, until one impacts at which time the impactor can cause a major extinction event (sometimes killing over 90% of life on land) and thereby major changes in the direction of evolution.


There is no way to know for certain, but no indication of Earth-type lifeforms has been seen or detected on the asteroids visited by spacecraft so far.


its possible what made life on earth possible.


LIFE. Also that many fewer asteroids floating around that could slam into earth and end all life.


No, but it might possibly be theorized that the materials required to spark life on planet Earth could have been delivered in this way. Comets and meteors are also possibilities of the same effect.


The sun affects life on Earth by being the source of most energy on Earth.



no..... asteroids don't support life. there is no atmosphere around asteroids which can hold air we breathe . asteroids are rich in minerals and missions to asteroids are being planned in order to mine them


The troposphere is where most life on earth lives. It is where we have our air and makes our weather.


Yes Suzie, there is life on earth and someday we will find it. It might even be intelligent.


Most asteroids are in the Asteroid Belt between Mars and Jupiter. But a few do come close to the Earth; these are called Near Earth Asteroids. You can see a list of NEAs, and the dates that they will come closest to the Earth, at www.spaceweather.com. Asteroids and comets have collided with the Earth in the past, and someday one will collide with Earth in the future. Depending on the mass of the asteroid, the damage could be catastrophic. 65 million years ago, scientists now believe that an asteroid or comet hit the Earth, causing the extinction of the dinosaurs and most life on Earth.


Destroying the ozone allows UV. These affect life on earth.


because all things in our life affect each other


Carbon is essential to life. Life could not exist without it


earth might not be the only place where life was created


Not getting new thing from different places



WELLL... mares is around 200,894km from earth! earth has life were as scientist have study there might be life or might not!.. hope this has answered ur questions.. if no BAD LUCK!
