The RoleMaster Classic version of Spell Law, as opposed to the RM2 or RMSS versions.
The section on Elemental Spells has a breakdown on pages 73-75 of how each of the specific element types affects the environment, in terms of starting fires, breaking things, noise, frost, ice, melting things, shattering things, conducting electricity onto other targets, etc.
It leads into the "Material Objects and Structural Integrity" section.
It's one of the sections of completely new material added to the book.
