Answer 1

Answer:

The correct answers are :

• It forms ozone in the stratosphere.
• It ionises atoms and molecules in the thermosphere.

Explanation:

• Ionising radiations like the cosmic rays are responsible for:

1. Breaking of oxygen molecules in the stratosphere to yield nascent oxygen which again reacts with oxygen molecules to form Ozone.
2. The molecules of different gases present in the thermosphere are radiolysed by these ionising radiations generating ions and huge amount of heat energy. This energy is responsible for the higher temperature in the thermosphere.
