Question

state the properties of troposphere and ionosphere?​

Answer 1

Answer:

Properties of Troposphere :  

1. It extends to a height of 18 km at the equator and declines gradually to a height of 8 km at the poles.  

2. Most of the weather phenomena take place in this layer.  

3. It contains almost all the water vapour and most of the dust particles. It is a turbulent zone.  

4. The upper limit of troposphere is called tropopause.  

5. In the troposphere, the temperature of air decreases at an average rate of 1°C for every 166 metres.

Properties of Ionosphere :  

1. It extends from 80 km to 480 km.  

2. It contains electrically charged gas molecules which reflect the radio waves used in long distance communication back to the earth.  

3. The northern lights or aurora borealis are in this zone,  

4. The temperature in this layer rises to a very high degree because the molecules in this layer absorb X-rays and ultra violet radiation coming from the sun.

Answer 2

Answer:

Troposphere: It is the first layer of the atmosphere. It is the layer were living and non-living things interact with each other(biosphere).

Ionosphere: Ionosphere layer present in the Thermosphere helps in radio transmission.

Hope it's understandable and helpful.... :)
