You will be given a definition of a task first, then some input of the task.
Given a scientific passage and an answer, generate a question for the given answer.

Passage: Through the process of conduction, heat flows from warmer objects to cooler objects ( Figure below ). The lower mantle is heated directly by conduction from the core. In conduction , heat is transferred as atoms collide. Answer: conduction
Output:
What process involves the flow of heat from warmer objects to cooler objects?
