How igloos keep you warm?? Full video. Realityenvisioned
This is how they do it..
Ah, the fantastic world of igloos! Ever wondered how these snowy shelters keep you warm in freezing temperatures? Well, it's all thanks to some cool science. Let me break it down for you:

Insulation: Igloos are made of snow, which is an excellent insulator. Fresh, powdery snow contains lots of tiny air pockets. These air pockets act as insulation, trapping heat inside and keeping the cold air out. So, the igloo acts like a cozy blanket, protecting you from the chilly outside.

Body Heat: When you're inside an igloo, your body generates heat. This heat radiates from your body, creating a warm zone around you. The air inside the igloo then circulates and mixes with your body heat through a process called convection. So, it's like having your own personal warmth bubble.

Catenary Arch: The shape of an igloo is no accident. Real igloos have a unique shape called a catenary arch. If you were to cut an igloo in half, it would look like a gently sloping curve. This shape is super strong and stable. It helps distribute the weight of the snow evenly, making the igloo sturdy and resistant to collapsing.

Wind Protection: Igloos are often built in sheltered spots or with a protective wall made of snow blocks. This helps block the cold wind from directly hitting the igloo, reducing heat loss. So, it's like having a shield against the freezing gusts.

Smart Design: Inside the igloo, there are different levels or platforms. This design helps create a temperature gradient. Hot air rises to the top, while colder air sinks to the lower levels. So, the sleeping and eating areas are strategically placed to keep you away from the coldest air, providing a more comfortable environment.
