Erddruck
Erddruck refers to the pressure exerted by the Earth's atmosphere at a given location. It is the weight of the air column above a specific area. This pressure is not constant and varies with altitude, temperature, and weather conditions. At sea level, standard atmospheric pressure is approximately 1013.25 hectopascals (hPa) or 1 atmosphere (atm). As altitude increases, the air becomes less dense, and consequently, the atmospheric pressure decreases. This is why mountaineers often experience lower blood oxygen levels.
Temperature also plays a role in erddruck. Warmer air is less dense than cooler air, so areas
