Atmospheric pressure refers to the force exerted by the weight of the atmosphere on a unit area of surface. Essentially, it's the weight of the air above a given point on the Earth's surface. As you move closer to the Earth's surface, the weight of the air above you increases, hence increasing atmospheric pressure. Conversely, as you move higher in altitude, atmospheric pressure decreases since there's less air above you. This pressure is crucial for maintaining Earth's climate and supporting life as we know it.

The atmospheric pressure at sea level is approximately 100,000 pascals. Atmospheric pressure value is 101.325 kilopascals (kPa). However, atmospheric pressure can vary depending on factors such as weather patterns, altitude, and geographical location. For instance, high-pressure systems typically bring higher atmospheric pressure, while low-pressure systems bring lower pressure. Additionally, atmospheric pressure decreases with increasing altitude; at higher elevations, such as on top of a mountain, atmospheric pressure is lower than at sea level.
