If Earth's atmosphere contained twice as many molecules as it does today, the atmospheric pressure would also double. This is because pressure is directly related to the number of gas molecules in the atmosphere.
Yes, atmospheric pressure decreases as you go higher in the atmosphere. This is because the weight of the air above decreases with altitude. Additionally, at higher altitudes, there are fewer air molecules exerting pressure.
The electromagnetic force contributes to pressure in both water and the atmosphere. In water, this force between water molecules results in pressure, while in the atmosphere, the force between air molecules creates atmospheric pressure.
Atmospheric pressure is primarily caused by the weight of air above a specific point on the Earth's surface. Gravity pulls air molecules towards the Earth, creating a force that results in atmospheric pressure.
The higher the altitude, the lower the pressure becomes. One way to think of this is that the lower levels of the atmosphere, near the surface, are being pressed down by the molecules stacked above them, all of them drawn by Earth's gravity. Similarly, water in the oceans exerts a higher pressure the deeper you dive. Also, at the higher levels of the atmosphere, it is easier for molecules of lighter gases to achieve enough velocity to fly off into space.
Air pressure is based on the density of molecules in the atmosphere. Density is mass divided by volume or D=M/V. By increasing the mass of air, the density increases. Decreasing volume also causes the density to increase. A high pressure zone means air has more mass per unit volume. A low pressure zone means the air has less mass per unit volume.

Gauge pressure is the pressure measured relative to atmospheric pressure, while atmospheric pressure is the pressure exerted by the Earth's atmosphere on a surface. Gauge pressure accounts for atmospheric pressure, while atmospheric pressure is the total pressure exerted by the atmosphere.
Atmospheric pressure decreases with altitude because there are fewer air molecules higher up in the atmosphere, leading to lower air density and less pressure exerted by the air above.

Atmospheric pressure
A barometer measures barometric pressure. Which is also known as Atmospheric Pressure. That's the pressure in the atmosphere that pushes down on you. When atmospheric pressure falls it can be a sign of potential t-storms and/or rain. Whereas when it rises it can be a sign of potentially fair weather.
The atmospheric pressure on the moon is essentially zero because the moon does not have a significant atmosphere. Unlike Earth, which has a dense atmosphere that exerts pressure due to the weight of the air above us, the moon lacks this gaseous envelope and thus has almost no atmospheric pressure.
The energy source responsible for the motion of molecules in the atmosphere is the pressure caused by the weight of the air. This pressure gradient drives the movement of air molecules from areas of high pressure to areas of low pressure, creating winds and atmospheric circulation patterns.
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.
Atmospheric pressure is the force exerted by the weight of air in the Earth's atmosphere. It is caused by the gravitational pull of the Earth on the air molecules and decreases with altitude.
Pressure decreases with altitude because as you go higher in the atmosphere, there are fewer air molecules above you exerting pressure downwards. This results in lower atmospheric pressure at higher altitudes.
