Atmosfäärejä

Atmosfäärejä is a Finnish term that translates to "atmospheres" in English. It refers to the gaseous envelope surrounding a planet, star, or other celestial body. In the context of Earth, the atmosphere is a crucial component of the planet's environment, supporting life and regulating climate. The Earth's atmosphere is composed primarily of nitrogen and oxygen, with smaller amounts of argon, carbon dioxide, and trace gases.

The structure of Earth's atmosphere is divided into several layers, each with distinct characteristics in terms of temperature, pressure, and composition. These layers include the troposphere, where weather occurs; the stratosphere, which contains the ozone layer that absorbs ultraviolet radiation; the mesosphere, where meteors burn up; the thermosphere, which is very hot but has extremely low density; and the exosphere, the outermost layer that gradually fades into space.

Understanding atmospheric composition and dynamics is vital for fields such as meteorology, climatology, and atmospheric physics. Phenomena like weather patterns, climate change, and the aurora borealis are all directly related to the properties and interactions within the atmosphere. The concept of "atmosfäärejä" can also be applied more broadly to other celestial bodies, where their atmospheres, if present, play a significant role in their physical and chemical processes.
