Atmosphere (physical space)
The atmosphere is the layer of gases that surrounds the Earth, retained by the planet's gravity, and is composed of approximately 78% Nitrogen, 21% Oxygen, and 1% other gases. The atmosphere plays a crucial role in supporting life on Earth, regulating the planet's temperature, and influencing the weather and climate. The atmosphere is divided into several layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere, each with distinct characteristics and functions. The study of the atmosphere is essential for understanding various phenomena, such as Weather patterns, Climate change, and Air pollution. Researchers use tools like Spectroscopy and Remote sensing to analyze the atmosphere and its components.
