It is the chief cause of warming in the troposphere.
It is the chief cause of warming in the troposphere.

It forms ozone in the stratosphere.
It forms ozone in the stratosphere.

It ionizes atoms and molecules in the thermosphere.
It ionizes atoms and molecules in the thermosphere.

It helps atoms to escape Earth's gravity in the exosphere.

Answer 1

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

Briefly: high-energy UV splits O2 to produce O and O3 in the stratosphere, and extreme UV/X‑rays ionize upper-atmosphere gases (the ionosphere in the thermosphere). Ionizing radiation is not the main cause of tropospheric warming, and atmospheric escape in the exosphere is driven by thermal and solar-wind processes rather than direct ionization alone.
