How do Igloos keep you warm?

A: How do Igloos keep you warm?

B: I’m a little busy, so I’ll tell you later.

A: All right. I’ll explain. Heat is a form of energy present in our body. When the temperatures around us are low, we begin to lose heat.     The more we lose heat, the colder we feel.  Now, although Igloos are made up of blocks compressed snow, they keep us warm.

B: Oh, stop baffling. How’s that possible.

A: Compressed snow has air trapped in it, and air is a bad conductor of heat. Hence, the heat given off by our body does not get lost from Igloo. It stays in the Igloo, thus keeping us warm. Besides this, we know that warm air rises up and cold air sinks to the  bottom. Hence, during night Eskimo that are people living in igloos sleep at the upper most part of the Igloo to stay warm.
