Which is the most harmful to life on Earth and why?

Answer by tiger b
Do your own homework!!!. You can use anything as simple as a dictionary. Or much better but, the glossary that usually comes in the back of a science text book.

Answer by quantumclaustrophobe
An asteroid is a rock, or collection of rocks, that orbits the sun.

A Comet is largely created up of ice, with some rocky material.

A meteor is a rock which enters the atmosphere of a planet.

They can ALL be harmful, but I guess we’re in worry of the asteroid the most.

Answer by Arkalius
A comet is most hazardous. A meteor is not an object, it is an occasion, when a meteoroid enters the Earth’s atmosphere and creates a visible streak from the intense heating due to the ram pressure from it really is higher speed. Meteoroids are generally really tiny and need to one particular hit the surface of the Earth, it would not produce an impact powerful adequate to endanger significantly of something in most instances.

Asteroid impacts can definitely kill us all if the asteroid is huge adequate. However, asteroids tend to hang out within about 4 AU of the sun, and therefore their orbital speed is in no way that much greater than that of Earth’s. Also, since they are never ever really far away, chances are we will be able to spot a dangerous asteroid a great extended time prior to it will hit us, giving us some type of possibility to prepare.

A comet on the other hand will be coming from the far outer solar technique on a hugely eccentric, or even open hyperbolic orbit, which indicates it will be moving much faster than an asteroid. This indicates it has a lot much more kinetic power per kilogram and will produce a significantly heavier influence than a similarly sized asteroid would. Also, we are unlikely to see an incoming comet till a couple months or even a couple of weeks before it reaches us giving us practically no time to prepare or try to deflect it, wihch would be really tough anyway considering it is speed.

Author Peter William Clements new book, No Want for God devotes itself to give answers to the queries which people have attempted to answer because the dawn of civilization: Exactly where do we come from? Where are we going to? What are we right here for? What the hell’s it all about? In his belief that Catholic Theologians consciously fail to revise and rebuild the intellectual architecture of their faith and due to the fact they deliberately refuse to accommodate the discoveries of science, Clement bravely measures out to share his findings that contradicts what most theologians made all Roman Catholics believe.

&#13

Getting been a student of catholic theology for far more than 65 years, and possessing spent seven years soon after his retirement into scientific analysis, Clement asserts that learning and understanding of contemporary science is incompatible with the dogmas of Roman Catholicism. His arguments and his points are summed up in the part of his book that says:

&#13

The findings of modern neuroscience prove with carloads of experimental and observational date that, without having the material substrate of the brain, there can be no consciousness: that is, there can be no soul that survives the death of the physique. The correlative point is that we now have empirical proof that ‘God’ did not magically inject a supernatural soul into a single-celled zygote at the precise moment of its conception simply because there is no such entity. Catholic Theologians can not recognize the truth empirically demonstrated by modern neuroscience the reality that there is no such entity as a supernatural soul. Their only recourse is to preserve a policy of inflexible obscurantism in plainer words a ‘theology’ of systematic prevarication.

&#13

With the use of arguments from science (in layman’s terms) evolutionary biology, geology, archaeology, anthropology, particle physics, astronomy, and cosmology Clement was in a position to demonstrate the validity of his proposition all summed in 4 words No Require for God.
