I don't just mean the earth itself but all the things on it also. For example there is now millions of cars and houses but they all came from raw materials from the earth. I guess some of the oceans have evapourated a bit but does that water come back to earth???

The mass of the Earth increases by about 40 tonnes per day due to micro meteorites striking the planet, so over a 1000 year period that's an increase of about 15 billion tonnes.

Hard to say.
We have satellites, probes and shuttles which are no longer part of the earth and have burned earth fuels in space. Also, some man-made chemical reactions have probably caused chemicals to leave the atmosphere.But - we also have space garbage (meteors and such) entering earth's atmosphere frequently. It would be hard to say, but I think that items entering the atmosphere probably outnumber what we have put out there.
However, this amount is incredibly small compared to the total weight of earth - so YES the earth does weigh the same (give or take a few thousand pounds)

The mass and for that matter weight of earth has not changed in the last 1000 years for following reasons:
(1) The houses, automobiles, human population has increased but its only re-distribution of matter from within the earth. So this would have no effect.
(2) Burning of all kinds of fuel generates ash and gases that remain in the earths atmosphere and is again part of a giant recycle or transformation of state of matter or transformation of one matter into another. So this would have no effect.
(3) The meteorite falls - yes this adds to the mass of the earth though insignificant.
(4) The space ships, satellites burn out in outer space contribute in loosing material out of earth- yes this is loss to the mass of the earth though insignificant.
(5) The evapo-transpiration is again part of hydrological cycle - this causes no loss of water.
Except (3) & (4) nothing changes the mass of earth.
The raw matter conversion of biotic-abiotic mass does not alter the mass/weight of earth .

The earth doesn't HAVE a 'weight'. That would require a really large scale and a place to set it. But the earth is constantly being bombarded by meteorites and other cosmic debris. this more than makes up for any lost hydrogen or oxygen that escapes into the solar wind.

The known mass of the universe enlarge's as science find's more trillion's of star's, each epoch of our journey. The weight of planet earth is so microscopic that it is likened to a grain of sand in the pacific ocean. The gravity of our planet determine's the weight, as legally a kilo is parisienne standardized. Therefore the planet earth get's more meteorit'es and ice from space, but no one know's, ;if blue planet earth conveert's this mass of rock and ;ice into added weight, gravitational wise, and if you know tell us

The mass of the earth is increasing all the time because of meteorites space dust etc.
I cant remember the amount but it may be as much as 1000 truck loads a day.
in 1000 years then 365 000 000 truck loads.
or 2 000 000 000 ton.
Would it make a big difference? Not really because it is a small percentage.

meteors are constantly falling to earth ("falling stars"), raising the weight of the earth.
also, every day, the earth is bathed in the weight of photons from the sun and the more-negligible weight of dust floating in general in space.
on the contrary, weight is lost when light and heat is expressed from the earth.
On the whole, though, the earth is getting heavier. More matter is falling to the earth than is escaping from the earth.

No, the earth weighs more now. Every year asteroids rain down on the earth and break up into dust and small rocks but it is a significant amount.

It all depends how you look at it.Yes,all things come from this earth,such as cars,food,water,houses,even people.I would imagine the earth is probebly the same weight that it was 1000 years ago.Besides,in earth time,1000 years is nothing.This earth is around 4.5 billion years old,most people say.That is 4.5 million thousand year chunks.

Every day the earth is still accumulating mass in the form of thousands of tons of micrometeorites that fall onto it from outer space. It really is that simple!
