The Layered Atmosphere: A Protective Shield

 

The Layered Atmosphere: A Protective Shield

Earth's atmosphere is a complex system of layers, each with distinct characteristics. These layers protect life on Earth from harmful radiation, regulate temperature, and facilitate weather patterns.

The Layers of the Atmosphere

1. Troposphere:

   • The layer closest to Earth's surface.
   • Contains most of the atmosphere's mass and where weather occurs.
   • Temperature decreases with altitude.

2. Stratosphere:

   • Contains the ozone layer, which absorbs harmful UV radiation from the Sun.
   • Temperature increases with altitude due to the absorption of UV radiation by ozone.

3. Mesosphere:

   • Temperatures decrease with altitude in this layer.
   • Meteors burn up in this layer.

4. Thermosphere:

   • Temperatures increase rapidly with altitude due to the absorption of high-energy solar radiation.
   • This layer is where auroras occur.

5. Exosphere:

   • The outermost layer, gradually merging with space.
   • Very thin and extends far from Earth.

Understanding the structure of the atmosphere is crucial for studying weather patterns, climate change, and space exploration.
