1 atmosphere for every 10m
Not much. You create slight changes in pressure when you breathe, but it's almost insignificant.
Much thicker, almost certainly at least as thick as the diameter of the earth. Its pressure is much higher as well due to the high mass of the planet and its atmosphere and the strong gravity.
About 600 pascals. For comparison, standard atmospheric pressure on Earth is about 101 kilopascals.
1 atmosphere for every 10m
Atmospheric pressure is another name for air pressure. This is because the atmosphere is pretty much the same as air.
I'm not sure what a "heavy" atmosphere is but Venus' atmosphere is denser than Earth's and the atmospheric pressure at the surface is much greater than Earth's
the atmosphere around us is troposphere in which we live and it is present upto 20km above earth..
Pressure decreases. This is because atmospheric pressure is a measure of the weight of the atmosphere weighing down. If you are high in the atmosphere, much of the atmosphere is below you so the pressure from above will be very small.
The moon is much smaller than the Earth and has a weaker gravitational field. As a result, gas on the lunar surface leaks away into space, rather than forming an atmosphere. And with no atmosphere, there can be no barometric pressure.
the answer is one atmosphere
Generally, atmospheric pressure is greatest at ground level, because you are at the bottom of the 25 mile thick atmosphere of earth. Greatest water pressure in a swimming pool is at the bottom, too. As you go up into the atmosphere, the pressure tends to decrease.
