The Earth's atmosphere is divided into five layers based on temperature and composition: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
1. Troposphere: This is the lowest layer of the atmosphere, extending from the Earth's surface up to about 10-15 kilometers. It is where most weather phenomena occur, as it contains the majority of the Earth's clouds, precipitation, and atmospheric gases. The temperature decreases with altitude in this layer, which creates convection currents that drive weather patterns.
2. Stratosphere: The stratosphere extends from the top of the troposphere to about 50 kilometers above the Earth's surface. It contains the ozone layer, which absorbs and scatters harmful ultraviolet radiation from the sun. This layer is important for regulating the Earth's temperature and protecting life on Earth from the sun's harmful rays.
3. Mesosphere: The mesosphere extends from the top of the stratosphere to about 85 kilometers above the Earth's surface. It is the coldest layer of the atmosphere, with temperatures dropping as low as -90 degrees Celsius. This layer plays a role in the formation of noctilucent clouds and meteor showers.
4. Thermosphere: The thermosphere extends from the top of the mesosphere to about 600 kilometers above the Earth's surface. It is the hottest layer of the atmosphere, with temperatures reaching up to 2,500 degrees Celsius. This layer is where the auroras occur, as charged particles from the sun interact with the Earth's magnetic field.
5. Exosphere: The exosphere is the outermost layer of the atmosphere, extending from about 600 kilometers to 10,000 kilometers above the Earth's surface. It is where the atmosphere transitions into outer space, with very low densities of gases. This layer plays a role in the escape of gases into space and the interaction with the solar wind.
Each layer of the atmosphere plays a crucial role in the process of weather and climate. The troposphere is where most weather phenomena occur, such as clouds, precipitation, and storms. The stratosphere helps regulate the Earth's temperature by absorbing harmful UV radiation. The mesosphere influences the formation of clouds and meteorological events. The thermosphere is where the auroras occur, and it plays a role in the Earth's energy balance. The exosphere helps regulate the escape of gases into space and the interaction with the solar wind. Overall, the layers of the atmosphere work together to create the Earth's weather and climate systems.

Layers of the Atmosphere:
1. Troposphere (0-10 km)
- Closest to Earth's surface
- Contains most of the air we breathe (75%)
- Where weather phenomena occur (clouds, rain, wind)
- Temperature decreases with altitude
2. Stratosphere (10-50 km)
- Ozone layer (15-35 km) absorbs harmful UV radiation
- Temperature increases with altitude, due to the absorption of UV radiation by ozone
- Contains weather balloons and airplanes
3. Mesosphere (50-85 km)
- Temperature decreases rapidly with altitude
- Contains meteors that burn up as they enter the atmosphere
4. Thermosphere (85-600 km)
- Temperature increases sharply with altitude, due to the absorption of solar radiation by molecules
- Contains the aurora borealis and aurora australis
5. Exosphere (600 km - Space)
- Outermost layer
- Very thin and diffuse
- Fades into space
Role of Each Layer in Weather and Climate:
1. Troposphere:
- Determines daily weather conditions
- Convection currents cause the rise and fall of air masses, leading to weather systems
- Contains water vapor, which condenses into clouds and precipitates as rain or snow
2. Stratosphere:
- Protects Earth from harmful UV radiation
- Temperature inversion stabilizes the layer, preventing major weather events
- Contains the jet stream, which influences global weather patterns
3. Mesosphere:
- Absorbs meteors and protects Earth from debris
- Cold temperatures prevent convection and weather formation
4. Thermosphere:
- Expands and contracts due to solar activity
- Influences satellite communication and GPS signals
5. Exosphere:
- Gradually merges into space
- Has little direct impact on weather and climate on Earth's surface
