Yes, it does. I've read that something like 60 tons a year is gained from objects captured by Earth's gravity.

Ok to clear this one up...yes it gains 'Mass' all the time. It barrles along in space through dust and asteroids and lots of other stuff, and picks them up like a magnet. Whats lost from earth into space is tiny compared. Remmber gravity is an effect and gives us a perception of weight. But all in all the effect is, we get some funky stuff from space that may or may not contain life and other intresting stuff, also we get water and minerals from out there as well.

Also when we destroy an item on earth ie burn wood. It still has the same mass once its gone, thats if you could collect all the atoms , all thats happend is, its been broken down into base components.

I think we're talking about mass here, not weight due to gravity.
Nothing that matters much has left the earth and, with all the births, including animals and such, I'd say that the earth is much, much heavier than it was at the outset.
Even with all the people who have died in that time, their remains are still on earth.
The amount gained isn't calcuable,

Keep in mind that earth is also losing mass every day due to the atmosphere being swept away by the solar wind. The elements that make of the atmosphere ultimated come from volcanoes. This may be more than influx of matter from space. Hard to say.

This question has 2 acceptable answers-

1)Because the Earth is gaining Mass from interstellar matter collected by its gravity it IS getting Larger but not necessarily heaiver
2)The Earth is becoming lighter in terms of of weight, because weight is determined by gravity and Earth is drifting away from the Sun because the universe is expanding therefor lessening the gravity and in turn the weight is smaller, even though the mass could be increasing.

Yes, Earth gains anywhere from 1,000 to 80,000 tons of mass per day (which varies depending on who you ask) from space debris. Compared to the total mass of the Earth, however, this amount is insignificant.

Mass cannot be created or destroyed, so its mass due to the substances within it (e.g. trees growing from seeds...) are due to the change from one form to another.

However, everyday, some debris from space does indeed fall onto our Earth, and it is the debris that results in the increase in the mass of our Earth.

It gets heavier!

no, the earth is actually getting lighter in theory. this is due to the expansion of the universe, all of solar systems are moving away from each other, and as this happens we are being slowly removed from our current orbit round the sun. therefore there is less gravity acting on the earth and we are getting lighter.
