Absolute pressure 10 meters below the water's surface is twice the standard atmospheric pressure. So that doesn't mean we weigh twice as much? I'm not making anything up. It is called Pascal's principle. It allows hydraulic jacks, hydraulic presses and so to work. Easy to understand for normal people.
What's the matter with you? can't you process the fact that I've never mentioned weighing heavier 10 meteres underwater, so what are you making this crap up for?
By definition of pressure I meant its demonstration from the forces exerted on a differential fluid element. Too difficult for you, forget it.
Can't you type normal and just say what you mean?
http://en.wikipedia.org/wiki/Gravimeter This is how a gravimeter works. Still doesn't explain why we can detect certain minerals with it. You can use a barometer to measure the atmospheric pressure on the building, leave all the windows open if you want to. It will show the same results.
Agitation of matter changes atmospheric pressure. It can be a minute change or a easily viewable change. A barometer may not pick up certain tiny hanges but a more delicate mechanism would. Hmmm, maybe a gravymeater.

They're all pressure gauges with different ways of measuring it. That's all.
If only you believed what you were saying... Anyway, you are probably the best troll I've ever seen in the internet, I give you that. Coming to this webpage to play the same character for years, that's dedication!
I'm dedicated because I'm a genius of the basics. I can see what you can't. Why?...because I use logic to determine things. I use common sense to decipher what those in labcoats try to baffle the average Joe with bullshit, probably unknown to them that they are actually doing it, as most are simply just the same as the people they teach. Parrots.
When I believe I'm right, you have to work very hard to make me change that belief and you can't do it by spouting bullshit.
Now, denpressure has destroyed your gravity that you hung onto like a limpet.
There's no special case for this Earth. How it works is all around you if you can observe.
Go along happily with the bullshit. It matters not, to me. If you are true to yourself though, you will sit and think about what I've said and do it with an mind that can think outside of the box. This way you never know, you may see things a lot differently.
I doubt it but you may surprise me.
