Which of these statements does not refer to radiation a. some of this energy is is reflected off earths atmosphere b.warm air rises and takes heat with it eventually it cools and sinks c.sunlight travels through space without aid of fluids or solids d.land and ocean absorb and re-emit heat from the sun quick

B.warm air rises and takes heat with it eventually it cools and sinks

Explanation: There are three modes of heat transfer:

1. Conduction: This type of heat transfer happens when there is direct contact between the two object.

2.  Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases and thus it moves upwards.

3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.

Warm air rises and takes heat with it eventually it cools and sinks  is an example of convection and not radiation.
