The Earth's atmosphere consists of several layers, each with unique characteristics. Here are the layers from the ground up, along with some key points about each:
1. Troposphere:
- Closest to the Earth's surface.
- Where weather occurs.
- Contains the majority of the atmosphere's water vapor.
- Temperature decreases with altitude.
2. Stratosphere:
- Contains the ozone layer, which absorbs and blocks most of the sun's harmful ultraviolet (UV) radiation.
- Temperature increases with altitude due to the ozone layer.
3. Mesosphere:
- Temperatures decrease again with altitude.
- The mesosphere is where meteors burn up upon entry into the atmosphere.
4. Thermosphere:
- Very high temperatures due to the absorption of solar energy.
- Contains the ionosphere, which aids in radio wave propagation.
- Astronauts orbit in this layer, but the air is extremely thin.
5. Exosphere:
- The outermost layer.
- Gradually transitions into space.
- Very low density, with few gas molecules.
- Satellites and space stations orbit within the exosphere.
These layers vary in thickness and composition, and they play critical roles in protecting life on Earth and influencing our climate and communications systems.
