How can the earth be 100,000 tonnes heavier that it was last year?

Answer 1

Meteor dust alone accounts for most of it, roughly the amount of cosmic dust the falls on the earth per year is about the size of a shoe box full per acre of every acre on earth. Which is about, give or take 44 billion acres. That's a lot of shoe boxes full of cosmic meteor dust every year. Meteor dust is consisted of 91% of iron, 7% of nickel, 0.5% of cobalt, as well as a small amount of platinum and iridium. Knowing that a shoe box full of iron would be quite heavy you know where all the weight gaining the earth gets each year comes from. Hope this answers your question.

Answer 2

there is no possible way for the earth to gain mass other than from astroids or somthing of the like. its a simple law that every first semester chemestry student learns: conservation of mass. atoms cannot be created or distroyed. they can only be recombined in different forms to make different materials. so unless 100,000 tonnes of astroids have made it to the earths surface this year, your facts are wrong

Answer 3

I'd never heard of that piece of data, and I'd like to know where you heard it and how reliable their information is.

Truth is, the only way for earth to gain mass like that would be if it came from in space, in the form of meteorites (they do it all the time, too small to actually make an impact on the ground, most of the time, usually just burning up in the atmosphere for the particles to slowly descend to earth). We can't make our own mass on earth, since the things we make have to come from something that's on earth already.

Answer 4

There is a specific answer to what you ask, and it has nothing to do with what has been proposed. The answer lies in one of the aspects found in the physics trilogy which is: E = mc2, m = E/c2, and c2 = E/m. The last of the three is that of a field of gravity. It describes the basis for the existence of this force. In that the force of gravity performs work, it must have an energy source. If this were not true, then the force of gravity would be that of a continuous field being continuously created in all matter at all times.

Because this force is one of energy to mass relationship, if one were to increase the value of "E" relative to that of the mass, a field of gravity would also be increased. Or, a person could decrease the mass ratio to that of energy and the same would happen.

Answer 5

Some matter must be coming to the earth from space or our own upper atmosphere. The stuff that is already here can change form, move around, or change in density, but it can't not change its own mass. Things don't just disappear or appear, even atoms.

Answer 6

Who said it had? All matter on earth must be the same even in some other form so I cant see how the earths weight can alter either way............unless I'm missing the plot somewhere?

Answer 8

More product has been produced to compensate for growing consumer demand

Answer 9

a comple thousand rocks from space landed on earth.

Answer 10

More crops grown, more animals etc. These come from no weight (hardly) and can grow to weigh a lot e.g Cows and Americans
