An igloo is a formation built from blocks of compressed snow, which are carefully placed to fit in ideal positions. Igloos are mostly associated with Inuit culture. People in snowy regions will often build these structures in the winter. An igloo is sometimes called a "snow house." The typical igloo is dome-shaped with chunks of ice built up in a vortex. The roof has a small hole for air circulation, and the entrance is dug into the snow, so that is beneath the igloo itself.
The placement produces a cold trap so that the igloo remains warm enough. The construction process of building an igloo is very complex and interesting. The blocks are cut from snow, which is densely packed, ensuring it will be made secure. When North Americans build it, they add skins and furs to keep warm. A basic igloo stays warmer inside than outside in the snow because the packed snow insulates.
Building an igloo house is quite easy; just make sure you get the right equipment to use. The first thing to watch out for when you want to build an igloo house is the location; find a place where the snow is dry, hard, and closely packed together. Then you use the snow saw (knife) to cut out your snow into blocks. The snow will be cut in cuboids’ form of about 15 inches of length, breadth of 3 inches, and a high of about 8 inches. This is to ensure that your igloo is strong enough and to make it last.
After you might have cut your ice, smooth the edges and place it round in a circular form. Then you put more ice blocks that you have cut on it. Mind you, the blocks at the upper part are to be smaller than the ones below. Do not forget to leave a space for entrance at the foot of your igloo house; you will also have to dig through the entrance. The blocks are to overlap themselves, making your construction be in the form of a dome.
