One is that when we are bored or tired, we just don't breathe as deeply as we usually do. As this theory goes, our bodies take in less oxygen because our breathing has slowed. Therefore, yawning helps us bring more oxygen into the blood and move more carbon dioxide out of the blood.

3. Why do icebergs stay solid even though they are immersed in water?

Icebergs are found in salty oceans. Salt helps in maintaining the freezing point of the ice, and the altitude of the water body and its elevation to the Arctic or Antarctic Circle decide the temperature of the water body and the freezing point of the iceberg. Water gets heated and cools down later than the Earth surface. So, once maintained, the cool temperature stays tuned for a longer duration.
