By mining materials that are burnt up in the atmosphere ,are we making the earth lighter,and so changing its axix..Could this be why the climate is changing..if it is?
hard to be non political,but the biggest lobby movement usually wins..power from coal, especially could have been lowered many years ago
ROFL... You guys are funny.
Isostasy - we'll float... but...
Just say the earth has a radius of around 6371 km, give or take, and the continental crust has a thickness of (say) 30 km to 50 km, give or take... and an area of 2 km by 0.5 km by 0.2 km (deep) is mined... and 50% of that material is exported, the remainder is not... oh... I lost my point in waffle... oh yeah, it is so insignificant, that even if it did make a difference, we'd float!
As plants receive energy from the sun and deposit their residue do they not add matter to the earth?
As we dig up and burn various materials, they float around in the atmosphere for some time and eventually return to earth. The effect is neutral.
There will come a time in the not too distant future when we will start to mine the solar system for minerals rare and expensive on Earth. As times go by we will become richer as we exploit the solar system. Earth's mass will increase as our wealth increases.
Every year Earth gains about the weight of two aircraft carriers landing on it. 40,000 tonnes-worth of debris lands on Earth. You can demonstrate this for yourself. If you put a big plastic sheet or a white sheet on your grass in the garden on a nice day, leave it for a few hours and then run a magnet over it. You can often find specks have just fallen down from outer space and landed on your magnet. Debris, dust and other stuff raining in from space contributes a huge amount of weight to the Earth every single year.
Yes, we do gain weight.
people have short ,memories,,Len Hancock,,midnight oil..asbestos..Gina is very rich.and money is not her zenith now,
If you burn something in a closed environment, say in a glass container that was air tight, the weight of the system wouldn't change.
In an open environment it would appear that there is less weight as some would be lost to the environment.
