Base your answer to the following question on the diagram below. Students completed a lab investigation consisting of four stations, A, B, C, and D. Equal amounts of sand at the same starting temperature were heated by identical light sources. The light sources were the same distance from each station, but at different angles to the surfaces. Two thermometers were used at each station, one just above the surface and the other just below the surface. The lights were turned on for 30 minutes and then removed for the next 30 minutes. Temperatures were recorded each minute for the 60 minutes. Which station shows the most light energy being transferred to the sand and why? 1. Station A, because the sand is receiving the most direct heat transfer by radiation

2. Station A, because the sand is receiving the most direct heat transfer by conduction

3. Station D, because the sand is receiving the most direct heat transfer by radiation

4. Station D, because the sand is receiving the most direct heat transfer by conduction
