Alright kiddo, imagine a big boat that is made of animal skins and is used by some people who live in a cold place with lots of snow and ice. This boat is called an umiak.
The umiak is very special because it is designed to help the people who use it to travel across the water without getting too wet or sinking. The boat is made from many different pieces of animal skin that are sewn together using special needles and thread.
The frames of the boat are usually made from wood or bones that are bent into a special shape to make the boat strong and sturdy. The umiak is also designed to be very wide and flat, which helps it to stay balanced when it travels across the water.
These special boats are used by people who live in places like Alaska, Canada, and Greenland, where the water is very cold and icy. They are great for fishing, hunting, and transporting people and supplies across the water.
So, in short, an umiak is a special boat made of animal skins and wood that is used by some people who live in cold places with lots of snow and ice. It helps these people travel across the water without getting too wet or sinking.
