Légkör
Légkör is a Hungarian term that translates to "atmosphere" in English. It refers to the layer of gases surrounding a planet, star, or other celestial body. In the context of Earth, the atmosphere is composed of several layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. These layers are crucial for supporting life on Earth, regulating temperature, and protecting us from harmful solar radiation. The composition of the atmosphere, primarily nitrogen and oxygen, is vital for respiration and photosynthesis. Weather phenomena, such as wind, rain, and clouds, occur within the lower layers of the atmosphere. Understanding the atmosphere and its dynamics is essential for meteorology, climate science, and aviation. The term légkör can also be used more broadly to describe the gaseous envelope of any celestial object. Changes in atmospheric composition or structure can have significant impacts on the environment and habitability of a planet.
