Which pair correctly matches atmosphere layer & feature?
ATroposphere weather
BThermosphere- ozone
CMesosphere - satellites
DStratosphere meteors.
Answer:
A. Troposphere weather
Read Explanation:
Structure of Earth's Atmosphere
- Troposphere: It is the lowest layer of the atmosphere where almost all weather phenomena like rain, fog, storms, and cloud formation occur.
- The atmosphere consists of five primary layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.
Key Layers and Their Unique Features
- Troposphere: Contains about 75% to 80% of the atmosphere's total mass and almost all of its water vapor. Temperature decreases with increasing altitude in this layer (Normal Lapse Rate: 6.5°C per 1000 meters).
- Stratosphere: Located above the Troposphere, extending up to about 50 km. It contains the Ozone Layer (Ozonosphere), which absorbs harmful ultraviolet radiation from the Sun. Commercial jet aircraft usually fly in the lower stratosphere to avoid weather disturbances.
- Mesosphere: Extends up to 80-85 km above the Earth. It is the coldest layer of the atmosphere (temperatures drop to -90°C). Meteors burn up in this layer upon entering Earth's atmosphere.
- Thermosphere: Extends up to about 600 km. It includes the Ionosphere, which contains electrically charged particles (ions) that reflect radio waves back to Earth, enabling long-distance wireless radio communication. Auroras (Aurora Borealis and Aurora Australis) occur here.
- Exosphere: The outermost layer of Earth's atmosphere, extending into space, where light gases like helium and hydrogen predominate. Satellites orbit Earth in this region.
