Solution
re-radiated by land and water
Explanation:
The heating of air occurs due to the re-radiation of solar radiation by land and water bodies. In fact, when the solar radiations fall on the earth, some are absorbed and the majority of these are reflected back or re-radiated by land and water bodies. These reflected or re-radiated solar radiations heat up the atmosphere.
