Atmospheric pressure is influenced by several factors, including altitude, temperature, humidity, and weather conditions. As altitude increases, atmospheric pressure decreases because there is less air above that point exerting a downward force.

Temperature affects atmospheric pressure through its impact on air density. Warmer air is less dense and exerts lower pressure, while cooler air is denser and exerts higher pressure. Humidity, or the amount of water vapour in the air, also affects atmospheric pressure. Moist air is less dense than dry air, leading to slightly lower pressure. Weather conditions such as high or low-pressure systems can cause temporary variations in atmospheric pressure.
