• A is false, and R is true.

Answer 1

Both A and R are true, and R is the correct reason for A.

Explanation:

The troposphere is also called the “changing sphere” because it is the atmospheric layer closest to the Earth’s surface, where all weather changes take place. The air in the troposphere is constantly in motion, containing most of the water vapour and solid particles, which are essential for cloud formation and weather phenomena like rain, hail, snow, and storms. Thus, both the assertion that the troposphere is called the changing sphere and the reason that all weather changes occur there are true and related.
