Yes. It is heavier through the bombardment by meteors, asteroids, comets, and another planet (which led to the formation of the Moon).
No.
Everybody gets heavier, and has a lot more trouble just moving around.
Yes, wolves are still found on earth.
YES, after eliminating the weight of any alien objects hitting earth from space it should weigh the same. It doesweigh the same; the earth's weight is zero. However, it is certainly more massive now than it was then. The above conclusion is problematic, because the 'alien' objects referred to are the very things that the earth is made of. Tons of material come down to earth each day.
a currently popular theory is that the moon came about when an asteroid collided with earth, ejecting what is now the moon into near-earth orbit.
No. Earth does not have enough mass to compress itself any more than it is now.
yes now shut up
no. If there were, we Earthlings would have ruined it by now.
Yes of course it did, and east and west and south. It started in Israel and now covers the whole earth..
Add seven pounds on to your weight. That's about how much you would weigh. Because Saturn has such low density, your weight would not be much heavier than what it is now.
What an existential question. We could all ask ourselves, "where on earth are any of us right now", and try to believe we're really on this earth. But perhaps we're not. Maybe this earth is just a concept borne of our own minds.
no, never. We have the same about of water now as we had since the start of the earth, therfroe we won't lose any now.
