The given diagram illustrates the process of construction of igloo from snow.
Overall, this procedure consists of eight stages, commencing with preparing for the conduct of snow saw and hard packed snow and culminating in igloo being formed and checked by people.
The eight-stage process begins when the processed steps of snow saw and hard packed snow are conducted. Thanks to this stage, the preparation of constructing the round-shaped wall is ensured in terms of safety, and
this wall has a length of 4 meters. Afterward, construction workers add numerous small blocks to the surrounding sector of the wall, which helps this architecture gradually become higher and larger. This structure is then provided with a button made of blocks to fill sufficiently for construction.
Once the additional process has been finished, the construction is experiencing a process of losing snow, with the height of 2 metres being expected to construct this wall. Subsequently, a new structure is created and its interior being prepared for a significant amount of air holes to help ventilation. Finally, a finished igloo will be formed and be meticulously checked by construction workers.
