WebAug 10, 2024 · Inside an igloo, heat can transfer via three methods; conduction, convection, and radiation. Our bodies are an example of radiation as they transmit heat to the insides of the igloo, making it warmer. Convection acts like a current, allowing this radiated heat to circulate on the inside of the igloo, increasing its internal temperature. WebJul 4, 2007 · Snow caves work for several reasons. 1) You are protected from wind-chill. Cold air moving past you pulls heat from the body because it maintains a steep thermal gradient. In the snow cave the air moves relatively little and hence you are warmer. 2) The white surface reflects heat back at you.
