Maybe no-one can answer this, maybe the answers will be massive speculation delivered with unprecedented authority, or maybe there is a definite solution. The question is out there now people, go to work!

Good, Good, some good answers here... All as I expected however! Perhaps 'Created' was a poor choice of words... tsk
All of you, give yourselves a well deserved pat on the back. Yeah

Also using the word 'weight' instead of 'mass' has made me feel very silly, but hey, you can't have a one without the other no?

This can be a trick question.
Earth as such does not really have a weight, because it is in orbit.
However it does have a mass.
That mass has gone up since the beginning as meteorites of various size fall each day. The estimate is that earth gains from 37000 to 78000 tons each year (see link). So, the Earth has been gaining mass since the beginning, and continues to do so.

Heavier due to increased population???? Some absolutely astonishing answers on here. Unless the population came from outerspace I cant see how increased numbers would make any difference at all! As others have pointed out, the planets mass is steadily increasing due to meteors constantly falling on its surface. Every few thousand years there's a big one maybe a kilometre across and smaller ones are more common - look up Tunguska to investigate the last major strike.
The moon was indeed ripped from the 'earths' mass but what we call the Earth I feel would begin after that separation so the answer is increased mass. There's always more stuff falling on our planet and no good way to get rid of it!

Ok, here you go.
the Earth was not created. It formed slowly over the course of billions of years. According to the accretion and solar nebula theories, the planets underwent a period of rapid growth as they accreted the material near thier orbits in the early solar system. The last part of this period, late heavy bombardment, was when the earth gathered most of the rest of it's mass (yes, the earth does not have a weight as previous writers have pointed out, it has a mass--weight is only relative to mass!)
However, at some point, a large body, perhaps as large as mars, collided with the earth. This caused the earth to GAIN mass, and the "splash" of this collision sent a small amount of material from the earth's crust back up into orbit. The moon formed from this splashed material--this is why the moon is so much less dense than the earth--it is made from crustal material!
After the moon formed (it did NOT break off from the earth) you could say that the earth was essentially "done" forming. If we start from that point and count forward, the earth (and moon) have been gaining mass ever since. Current estimates seem to be that the Earth gets about 40,000 tonnes of material added from space every year, in the form of dust, metrorites, and whatnot. This number is hotly debated, as there are no good ways to really measure infalling material with any accuracy.
So there you go. Yes, the earth is getting bigger.

A black hollow is a area of area from which no longer some thing, such as mild, can destroy out.if so how earth is destroy out from this??? round a black hollow there is an undetectable floor which marks the point of no go back, pronounced as an adventure horizon. that is called "black" because it absorbs all the mild that comes in the route of it, reflecting no longer some thing, a twin of a appropriate black body in thermodynamics.[a million] less than the idea of quantum mechanics black holes own a temperature and emit Hawking radiation.

Since it came into existence the earth has been bombarded with all types of matter,so it has probably put on a bit of weight in 6 billion years!

the answer can be delivered by an 11th grade physics student. Planets do not have weights, they are measured by their mass. Same as moons, starts, and anything else out there in space.

considerably lighter. This is mainly because the moon was once part of the earth and now is not.
Other than that, the earth gains mass from meteorites and asteroids, and loses it through evaporation of gasses (like hydrogen) for a net gain.

Heavier..
Lots of meteorites have hit us in the past few billion years since
the moon was created...

its probably heavy because of the increasin number of poeple bt it nt fallin cause the pressure of the universe is able to sustain the weight of the earth

so much space debris has bombarded us over the last 5 billion years, id say that it almost for sure has to be heavier.
