Why do igloos not melt if they have fire inside?
because there is a hole at the very top of the igloo and heat rises so the ice doesn't melt.
What is the Scientific reason why igloos don't melt?
Igloos used to be winter homes for Canadian and Greenland Inuits (the people sometimes called Eskimos). Inuits as a culture don't live in igloos anymore - there's no garage for the snowmobile. Igloos are made with blocks of snow about 2 feet by 4 feet and 8 inches thick. The top edges of the blocks are rounded so the structure forms a dome at the top. An experienced builder can make an igloo in less than two hours. At the top of the igloo is a hole to allow ventilation. This is also a key reason why igloos don't melt. The hottest air and smoke rise up through the hole. In the middle of an igloo, a shallow saucer burns seal blubber for heat and light. A high wood fire might melt the structure. But this wide, low blaze and the inhabitants' body heat keep the igloo relatively warm - between 45 and 60 degrees, experts say. That's not bad, considering it can be 40 degrees below zero outside. The inside wall of the igloo blocks does melt, to some extent. But the outside air is so cold and the building blocks of snow so thick that the blocks continually refreeze.
Why the inside temperature of igloos is high as compared to outside temperature?
Because igloose are made up of ice.
Can you light a penny on fire?
No. You can't light a penny on fire. If you get it hot enough you can melt the penny but it won't really be on fire.
Can a wooden button melt?
No, if the button was made of 100% wood it would catch fire and burn.
Why do igloos not melt if they have fire inside?
because there is a hole at the very top of the igloo and heat rises so the ice doesn't melt.
How do eskimos remain warm even though igloos are made up of ice?
Even though igloos are made up of ice, Eskimos stay warm because their body heat warms the air inside the igloos and the air inside becomes warmer than the air outside. Both air and ice are good insulators and they reduce heat loss from inside the igloos to the surroundings by conduction.
Why igloos are found in arctic region?
They melt.
Why igloos are found in arctic region only?
They melt.
Can igloos melt fast?
no because people sleepn in them.
Do igloos melt in the sun?
Not as long as the air temperature remains below freezing.
Why inside temperature of igloos is high as compare to the outside temperature?
ice is a bad conductor of heat. Any heat generated from inside the igloo, usually from body heat or a small fire, stays inside.
Eskimos choose to live in igloos which is made up of ice even the ice is coldexplain why?
Eskimos stay in there igloos, their body heat warms u the air inside the igloos and the air inside becomes warmer than the air outside. Both air and ice are insulators and they reduce heat loss from inside the igloos to surrounding by conduction..
Are igloos hot on the inside?
they are warm not hot or cold
What did the inuit use animals for?
food, warmth, and materials for inside their igloos.

How does an igloo protect the Inuit from polar bears?
Actually, igloos are ice structures and ice is an insulator. So, any heat(body heat or a small fire) from inside the igloo will be reflected back from the inner ice wall because ice is an insulator. The heat (Especially from a fire) does melt the inner wall of ice a little but the temperature outside the igloo is so cold that it refreezes the ice back. So, this insulation property of ice help the eskimos keep warm. You can check out the link for a more detailed explanation along with illustrations.
