Choose the situation that is an example of heat transfer by radiation. A. An ice cube melts while you hold it in your hand. B. Hot soup rises to the top of the bowl while cooler soup sinks to the bottom. C. Coastal temperatures are cooler than temperatures in inland areas. D. The sun's energy is transferred through the vacuum of space to the earth. I think it would be A, but I'm not quite sure. Please help, thanks!

    I remember back in 6th grade, we learned out how to remember Conduction, Convection, and Radiation. Imagine a classroom. The student in the front has a book that the student in the back needs. Key: Book = Energy/Heat Students in Class = Molecules Classroom = Universe Conduction: The student in the front passes it to the student sitting behind him, that student passes it to the student behind him and so on till the book reaches the student at the back. Convection: The student in the front, with the book, walks to the back of the class himself and hands it to the student who needs the book. Radiation: The student in the front throws the book to the student in the back, without it having to go through any of the other students.
