According Collier (1985) lightning is a minor weathering agent, in the sense that if it directly strikes a rock it may crack it or start a fire. Alternatively, it may just heat the boulder to excessively high temperatures, so as when it rains the cold water my cause the boulder to break up.

Emission of Infra Red, Ultraviolet and Gama radiation from the sun is why it is an agent of weathering.

No, weathering is the process or wearing rock and similar things down.

what are the agents of weathering
the nature of the material weathered (shape, size, composition) the nature of the weathering agent the frequency of the weathering agent the properties of the surrounding environment
-Mechanical weathering -Chemical weathering -Biological weathering
Unloading acts as a weathering agent by breaking bedrock into smaller pieces. This increases the surface area along which chemical reactions can occur, which eventually leads to weathering.
