igloos keep you from the snow inside that is built with it
The dome shape offers little resistance to the wind. It traps air pockets making it an insulator, not letting warm air escape.
According to experts, most Eskimos dwell in snow-shaped domes in the Arctic called igloos. Contrary to its appearance, the igloos keep Eskimos warm and comfortable inside.
they are warm not hot or cold
Actually they do. I guess its because the heat stays in.
Igloos so that it keeps them warm.
Gravity and friction are what keep igloos together.
to keep the at trapped in
they live off of the animals, fire and their cozy and warm igloos
in the winter they built igloos and summer the used animal skins to make tents
Hardly any Alaskan natives live in igloos. Most have regular houses. Igloos were useful because they could be readily made from items at hand (ice and snow) and lasted one or several seasons. Native Eskimos using ice and snow for housing is no more remarkable than the southwest Indians using clay or the northwest Indians using wood.
Inuit homes were made of snow. The Inuit shaped snow into hard blocks of ice. They made igloos out of the snow to protect themselves from the cold. Igloos were warm, small and comfortable for a temporary home.
As you probably know snow is made of water and water is a very good insulator. It also takes a lot of heat to warm it up and an igloo will insulate and keep your body heat in and keep the cold out but sometimes people will put small fires to make it warmer The dome shape enables it to use your body heat as a heat source for the igloo. and a igloo (if made of ice blocks) uses snow or more ice as mortar to hold itself together, so the colder it gets outside, the better the igloo will hold its shape, and, in theory, it should insulate against the cold better.
The reason igloos are built in the polar region is that it is cold enough to prevent them from melting. Igloos are built by stacking blocks of ice in a domed fashion.
