Answer 1

- It ionizes atoms and molecules in the thermosphere.
- It forms ozone in the stratosphere.

Reason: High-energy solar UV/X-rays ionize gases in the upper atmosphere (creating the ionosphere/thermosphere), and UV photodissociation of O2 produces O atoms that combine with O2 to make O3 in the stratosphere.
