When children learn about different types of houses in school geography, one of the most fascinating structures they study is the Igloo.
The direct Hindi translation of Igloo is 'बर्फ का घर' (Barf ka ghar) या 'हिमकुटी' (Himkuti).
Hindi Meaning: बर्फ का घर (Snow House).
Builders: Historically built by the Inuit (Eskimo) tribes.
Shape: A perfect Dome (अर्धगोलाकार).
Material: Built using compressed blocks of wind-blown snow.
Scientific Purpose: Uses snow as a massive thermal insulator to trap body heat inside during deadly winter blizzards.
An igloo is a special type of temporary shelter made entirely out of blocks of solid snow and ice. It is built in the shape of a perfect dome. It is historically built by the Inuit people (commonly known as Eskimos) who live in the freezing, harsh Arctic regions of the world (like northern Canada and Greenland).
It sounds impossible that a house made of freezing ice can keep you warm, but the science behind the Igloo is brilliant. Solid snow is full of millions of tiny air pockets, making it a fantastic thermal insulator. When Eskimos go inside the igloo and light a small oil lamp (or even just use their own body heat), the dome traps all the hot air inside. While it might be a deadly -40°C outside in the storm, the temperature inside the igloo can easily stay around a comfortable +15°C, preventing the people from freezing to death.
An igloo does not have a normal door. It has a long, underground tunnel leading into it. Because cold air is heavy, it sinks and gets trapped in the bottom tunnel, while the warm air rises and stays trapped up in the dome where the people sleep.
The Hindi meaning of an Igloo is 'बर्फ का घर' (a house made entirely of snow and ice blocks).
Historically, the native Inuit people (often called Eskimos) of the freezing Arctic regions lived in igloos during hunting trips.
Slightly. The heat inside does melt the very inner layer of snow, but the freezing wind outside instantly freezes it into solid ice, actually making the igloo stronger like a cement wall!
