Gravity.
Atmospheric pressure is the weight of a column of air. Of course, the temperature of that air changes it's density and therefore it's weight (i.e. pressure)
Atmospheric pressure will typically not cause outdoor Christmas lights to explode. Atmospheric pressure in most areas is typically not high enough to cause such lights to explode.
The cause is weight of the atmosphere.

Just as water pressure is caused by the weight of water, atmospheric pressure is caused by the weight of the air. Pg. 126 Conceptual Physical Science 4th Edition.
The weight of the liquid is, plus possibly the atmospheric pressure on the top surface of the liquid.
isobars are a measure of atmospheric pressure. variations in atmospheric pressure basically cause weather - high pressure vs low pressure, etc.
Atmospheric pressure
The cause is the pressure difference between the gas pressure in the bottle and the atmospheric pressure.
rain occurs in low atmospheric pressure.
because our body pressure is equal to the atmospheric pressure.
no Because any body subject is affected by the atmospheric pressure in the case of its occurrence under the pressure of what it means that the pressure for increased 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.
