with all the coal and oil being taken from the earth and burnt wouldnt the earth be getting lighter?

Answer 1

First,YOU MUST KNOW WHAT IS Law of conservation of mass.

The law of conservation of mass/matter, aka Law of Mass Conservation (or the Lomonosov-Lavoisier law), states that the mass of a closed system of substances will remain constant, regardless of the processes acting inside the system. An equivalent statement is that matter changes form, but cannot be created nor destroyed.

Since the waste produced v.i.z smoke, unburnt fuel , ash from coal weigh the same as that of the original fuel.
SINCE THESE PRODUCTS DONOT ESCAPE THE EARTH BY ANY OTHER MEANS, the mass of earth remains constant.
EARTH DOESNOT GET LIGHTER BY THE DAY.

Answer 2

Matter can be destroyed. (I.e the collisition between electrons and positrons; or any other form of matter/antimatter.) Matter, when destroyed, is converted into energy; generally in the form of photons. As far as the Earth getting lighter, the Earth doesn't weigh anything since it is our relativistic view point by which we measure weight. (If it landed on another planet then it would.) As far as the mass of the Earth, it is not getting smaller because gravity holds the air in the atmosphere. The Earth does get less massive when we send satellites or other such objects into outer space, but only negligibly. Yours Truly,

Answer 3

Kinda... The energy released from that burning of coal ect makes heat and that heat will excape from the earth at some point. But the earth is probably growing in size and mass if my theorys are correct and they very well could be crazy gibberish :) Anyhow to answer your question Its possible the earth is getting lighter then it was because we burn fuel yes but I dont know if its true or not. :)

Answer 4

Matter cannot be created nor destroyed, but i dont know if would float up to space or not, maybe it is, nothing to detrimental to the well being of earth though. Not as much as a nuke atleast
