The image is a diagram titled 'HOW AN IGLOO IS MADE OUT OF SNOW', illustrating an 8-step process for construction. Step 1 shows cutting hard-packed snow with a snow saw. Step 2 shows the lower portion of the dome built with an entrance. Step 3 depicts the dome being capped. A measurement of 4 metres is shown between the center of a circular base and the nearly completed dome. Step 5 illustrates applying loose snow to the exterior. Step 6 shows the igloo with an added entrance tunnel. Step 7 details the creation of interior air holes. Step 8 shows a person entering the completed igloo.

Overall, the process involves several stages, starting with the formation of snow bricks before the igloo is fully completed.
In the first stage, hard-packed snow is cut into small blocks using a snow saw. These blocks are then arranged in a circular shape to form the base of the igloo. On the next step, the blocks are stacked about 4 meters, gradually creating a dome-shaped structure.
Next, loose snow is used to fill the gaps between the snow blocks. This helps strengthen the structure and improves stability. After that, a small entrance tunnel is added to the front of the igloo, which is low and narrow, allowing people to crawl inside.
After completed every steps, the igloo becomes a warm and secure shelter despite being made entirely of snow.
