Key Differences
The atmosphere is a complex layer of gases that envelops the Earth, playing a critical role in protecting life by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. Whereas the biosphere refers to the global ecological system integrating all living beings and their relationships, including their interactions with the elements of the lithosphere, hydrosphere, and atmosphere.
While the atmosphere is composed primarily of nitrogen (78%) and oxygen (21%), with smaller amounts of other gases, the biosphere is made up of countless ecosystems, each with a diverse array of life forms adapted to their specific environments.
On one hand, the atmosphere's structure is divided into layers based on temperature variations, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. On the other hand, the biosphere is not defined by a physical structure but by the presence of life in various forms, from the deepest parts of the ocean to the highest mountains.
The atmosphere plays a crucial role in the Earth's water cycle and climate system, influencing weather patterns and climate change. In contrast, the biosphere is essential for the production of oxygen through photosynthesis, which is crucial for life and affects atmospheric composition.
Atmospheric phenomena, such as the greenhouse effect, are critical for maintaining the Earth's temperature. Meanwhile, the biosphere influences and is influenced by these phenomena, demonstrating the interconnectedness of Earth's systems.

Atmosphere
An atmosphere (from the greek words ἀτμός (atmos), meaning 'vapour', and σφαῖρα (sphaira), meaning 'ball' or 'sphere') is a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low.
Biosphere
The biosphere (from Greek βίος bíos "life" and σφαῖρα sphaira "sphere"), also known as the ecosphere (from Greek οἶκος oîkos "environment" and σφαῖρα), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth.
Atmosphere
