How an igloo is built from snow – Bài mẫu IELTS Writing Task 1

The illustration shows information about how an igloo is built from snow.

Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The given diagram illustrates the process of building an igloo, a type of dwelling made by the Inuit people. It can be seen that the igloo is made solely of snow and that at least 10 steps are required to create this sort of shelter.

Initially, only hard-packed snow can be used to make igloos because of its toughness and thickness. After being collected, the snow is sawed into rectangular blocks, of which the largest ones are used to form the base of the igloo. When the base is complete, the next blocks will have their edges smoothed by the builder to be placed on top one another, until a dome-like structure is shaped. Then, a hole is dug under the igloo’s wall in order to make an entrance, while on top of the dome, a significantly large block of snow will be used to cover the final opening. Thus, an igloo is shaped.

In the subsequent steps, softer snow is shoveled upon the igloo to provide further coverage, after which the builder makes sure that this snow is also packed tightly into all crevices between blocks. The inside of the igloo is burnished by hand, and afterward, the shelter’s entrance hole is covered with more snow blocks to prevent exposure to the cold. To conclude the process, small holes will be poked on the dwelling’s wall and roof to allow ventilation.
