If you stop and think about it, how could the weight change from building structures and so on? How could that possibly happen? If you move all the junk in your room from one side to another, have you changed the weight, or only the location? If you have water in a bottle that is standing up, does the weight change if you place the bottle on its side? (The answer--NO.) On the other hand, when we send satellites into orbit, we subtract a minute fraction of the earth's "weight" from the earth, so the weight changes downward.
If we leave out the preamble to your question, leaving only the part "has the weight of the earth changed," then the answer is YES, it changes probably every second as new material from the "outside," like meteors, and so on add tons to the earth every day.

All of the previous answers, although correct, neglect the fact that weight is the force felt of mass under the influence of gravity. The correct wording of this question should be "...has the mass of the Earth changed". Weight is an arbitrary measurement, based upon the mass and the local gravity. A persons mass might be 1000 newtons (the metric measurement of weight) on earth and 170 newtons on the moon. The weight has changed even though the mass remains constant.

No. Nuclear finding out has been minimum contained in the previous 20 years. If such tests were responsible for quakes and volcanoes we would have considered a rash of them contained in the 60's and 70's, something that only did not happen. i imagine the Mythbuster's in a unmarried of their experiments are extra likely to reason an earthquake than nuclear guns finding out. replace: the object you appropriate to is 4 years previous. If there changed into something to it do not you'll were waiting to locate something somewhat extra modern? Any time you spot a declare like this attributed to an unnamed source, that would favor to be a pink flag. I mean, come on. it really is only hassle-free experience.

the law of conservation of mass would say that it hasn't....whatever we build, we build from material we take out of the earth. whatever is destroyed, stays on the earth in a different form. aside from some space debris and dust (veeeeeeeeeery minimal and in all likelihood even in terms of what comes in and what goes out) there should be no difference...
Except for added human weight.

Not from what you mentioned - all the material was already on (or in) the planet. However , the earth gains mass by constsnt accumulation of dust and particles from space.

where do you think the material for those structures came from?
but the earth actually does pick up several tons of space dust a day

Yes because of occaisional meteors, but the amount of added weight is minimal.

it weighs 5 1/2 lbs more now

probably not because we are just using materals that are already on earth and the weight is already on earth

No, because nothing is every created using something that wasn't already here.
