Definition
The atmospheric composition and structure refer to the various gases that make up the Earth's atmosphere and the layers that organize these gases, which play a crucial role in regulating climate and supporting life.
Summary
The atmosphere is a vital layer of gases surrounding Earth, primarily composed of nitrogen and oxygen. It plays a crucial role in supporting life, regulating temperature, and influencing weather patterns. Understanding the composition and structure of the atmosphere is essential for grasping how it affects our environment and climate. The atmosphere is divided into several layers, each with unique characteristics. The troposphere is where weather occurs, while the stratosphere contains the ozone layer that protects us from harmful UV radiation. Greenhouse gases, such as carbon dioxide and methane, are critical in regulating Earth's temperature, but their increasing concentrations due to human activities are leading to climate change, which poses significant challenges for our planet's future.
