# What Is Atmospheric Pressure? A Comprehensive Guide **Atmospheric pressure** is the force exerted by the weight of air in the Earth’s atmosphere. It plays a crucial role in weather patterns, human health, and various industrial applications. Understanding this concept is essential for scientists, engineers, and everyday life. ## **Defining Atmospheric Pressure** **Atmospheric pressure** refers to the pressure caused by the weight of air above a given point. Measured in units like Pascals (Pa) or atmospheres (atm), it decreases with altitude. At sea level, standard atmospheric pressure is approximately 1013.25 hPa. **How Atmospheric Pressure Works** Air molecules have weight and collide with surfaces, creating pressure. Factors like temperature, altitude, and…

What is Atmospheric Pressure? A Comprehensive Definition Atmospheric pressure is the force exerted by the weight of air in the Earth’s atmosphere. Understanding this concept is crucial for fields ranging from meteorology to engineering. In simple terms, it’s the pressure created by air molecules colliding with surfaces. Defining Atmospheric Pressure in Detail To truly define atmospheric pressure, we must examine its scientific foundation. Measured in units like Pascals (Pa) or atmospheres (atm), standard atmospheric pressure at sea level is approximately 101,325 Pa. This pressure decreases with altitude as the air becomes thinner.
