That would depend on the mass of the black hole, and how close it came. A black hole the size of a star, a few light-years distance, would not be any more dangerous than a star at the same distance.
Black holes are out in space. Atmosphere is wrapped around a planet.
If a planet and its atmosphere came near enough to a black hole they would be pulled into it.
Okay i think i might know but i'm not sure but i think this can never happen because if it did the atmospheric pressure would crush us. our fluids in our bodies exert pressure on the atmospheric pressure(the same amount) and pretty much neutralize the effect!
They would bleed less profusely.
If you mean, who needs to know what the atmospheric pressure is, that would be meteorologists. If you mean, who makes use of the atmosphere, that would be everybody who breathes.
You would use a mercury manometer

the atmospheric pressure on top of a moutain would be lower than the atmospheric pressure down in a mine shaft
Think about this: if the pressure WERE equal, what would happen in the instant when you open the neck of the balloon and whatever pressure is on the inside meets the pressure that is on the outside (atmospheric pressure)? In your experience, what DOES happen?
It would expand as the gases inside expand against the pressure of the skin of the balloon and the atmospheric pressure.

Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
A human would be crushed by the intense atmospheric pressure, which is 90 times that of the Earth's atmospheric pressure.
Yes, Barometric Pressure and Atmospheric Pressure are the same thing. Except one describes what Atmospheric Pressure would be measured in.

Water boils when its internal pressure reaches that of the atmospheric pressure. Therefor, if one lowers the atmospheric pressure, the water would boil at a lower temperature (in fact, one can make water boil at room temperature by dramatically lowering the atmospheric pressure).
