Layers of the Atmosphere

• The atmosphere can be divided into $4$ layers: troposphere, stratosphere, mesosphere, thermosphere.

Troposphere

• Closest to the Earth's surface; weather occurs here; high air density.
• Pollutants and greenhouse gases trapped here, influencing climate.

Stratosphere

• Above the troposphere; ozone layer resides here.
• Less dense than the troposphere; shields Earth from UV radiation.

Key Takeaways

• Understanding the atmosphere's structure is essential for climate dynamics, weather patterns, and life-supporting processes.
