Ilmakehässämme

Ilmakehässämme refers to the Earth's atmosphere, the layer of gases surrounding our planet. This complex system is crucial for life as we know it, providing the air we breathe and regulating Earth's temperature. The atmosphere is composed primarily of nitrogen and oxygen, with smaller amounts of other gases like argon, carbon dioxide, and trace elements.

The atmosphere is divided into several distinct layers, each with unique characteristics. The troposphere, closest to the Earth's surface, is where weather phenomena occur. Above it lies the stratosphere, containing the ozone layer which absorbs much of the Sun's harmful ultraviolet radiation. Higher still are the mesosphere, thermosphere, and exosphere, each progressively less dense and hotter.

Human activities, particularly the emission of greenhouse gases, are impacting ilmakehässämme. This leads to changes in global climate patterns, commonly referred to as climate change, with consequences such as rising sea levels and more extreme weather events. Understanding the composition, structure, and dynamics of the Earth's atmosphere is vital for addressing these challenges and ensuring the long-term health of our planet.
