Omgivelsesatmosfæren

Omgivelsesatmosfæren refers to the ambient atmosphere or surrounding air. It encompasses the mixture of gases that form Earth's atmosphere, which is essential for life as we know it. This atmospheric envelope is held to the planet by gravity and is composed primarily of nitrogen and oxygen, with smaller amounts of argon, carbon dioxide, and trace gases. The omgivelsesatmosfæren plays a critical role in regulating Earth's temperature through the greenhouse effect, protecting the surface from harmful solar radiation via the ozone layer, and providing the necessary gases for respiration and other biological processes. Its composition and dynamics are influenced by a variety of factors, including geological activity, biological processes, and human activities. Changes in the omgivelsesatmosfæren, such as those caused by pollution or climate change, can have widespread and significant impacts on ecosystems and human societies. Understanding the omgivelsesatmosfæren is therefore crucial for environmental monitoring, climate modeling, and developing strategies for sustainability. The study of the atmosphere, known as atmospheric science, investigates its physical and chemical properties, its movement, and its interactions with other Earth systems.
