Study Notes
The Atmosphere
- The atmosphere is a thin envelope of gases surrounding the planet.
- It protects from harmful radiation and regulates temperatures suitable for life.
- It acts like a protective coat.
Atmosphere Composition
- Primarily composed of nitrogen (78%) and oxygen (21%).
- Minor components include helium, carbon dioxide, and water vapor (approximately 1% combined).
- Most gases concentrated near the Earth's surface.
Impact of Human Activities
- Burning fuels increases carbon dioxide (CO2) levels.
- Dust and ash can block sunlight, influencing plant life.
- Water vapor percentages vary geographically, ranging from nearly 0% in deserts to 4% in humid tropics.
Air Pressure
- Air pressure is the weight of the air column above a point.
- Barometers measure air pressure.
- Air pressure decreases with increasing altitude.
Atmospheric Layers
- The atmosphere is divided into four main layers.
Troposphere
- Closest layer to Earth, extending up to about 10 km.
- Contains weather phenomena (clouds, rain, wind, snow).
- Temperature decreases with altitude.
Stratosphere (Ozone Layer)
- Located 10-50 km above Earth.
- Contains the ozone layer, absorbing harmful ultraviolet (UV) radiation.
- Temperature increases with altitude.
Mesosphere
- Located 50-85 km above Earth.
- The coldest layer in the atmosphere.
- Meteors burn up due to friction in this layer.
Thermosphere
- Located above the mesosphere (85 km and higher).
- Temperatures are extremely high, reaching 1800°C or above.
Energy in the Atmosphere
- The Sun is the primary energy source for the atmosphere.
- This drives processes like the water cycle and air movement.
- Solar energy absorbed by the atmosphere helps maintain a relatively stable temperature on Earth.
Heat Transfer
- Heat transfer in the atmosphere occurs through conduction, convection, and radiation.
- Air heated by solar energy rises, creating air currents and winds.
- Winds move from areas of high pressure to areas of low pressure.
