Question

6. Give reasons:
a) Stratosphere is ideal for air traffic.
b) Thermosphere is useful for wireless communication​

Answer 1

1. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
2. The thermosphere layer of the atmosphere makes the radio communication possible on Earth. This layer is composed of several ions that reflect the radio waves back to Earth, making it possible to have wireless communication.
