Study Notes
The Atmosphere
- The atmosphere is a gaseous layer surrounding the Earth, influencing nearly all aspects of the physical environment.
- It's the outermost of four environmental spheres (hydrosphere, lithosphere, biosphere).
- The atmosphere is derived primarily from volcanic gases.
- It plays a key role in supplying oxygen, absorbing radiation, protecting the Earth, and enabling the water cycle.
Composition of the Atmosphere
- The atmosphere is a mix of gases and particles.
- Non-variable gases (mostly nitrogen and oxygen) make up over 98% of the atmosphere by volume.
- Variable gases (carbon dioxide, water vapor, ozone) exist in smaller but crucial quantities.
- Particulates (solids and liquids from Earth's surface) are collectively called "dust".
Vertical Structure of the Atmosphere
- The atmosphere is layered based on temperature differences.
- There are five main layers.
