Question

Why can the sun transmit heat to Earth only by radiation?

The space between the sun and Earth contains almost no matter.

Radiation transmits heat through the motion of a gas.

Radiation does not require the creation of electromagnetic waves.

The molecules in the sun are moving too fast to cause conduction.

Answer 2

Aaaaand which do you think? :P

Answer 3

A or C. I'm not too sure.

Answer 4

Radiation by definition is a form of electromagnetic wave. It's one method of heat transfer, just like convection or conduction, but what makes it unique is that it does not require matter for heat transfer to occur like conduction or convection.
