The wind chill is how cold it feels when the effect of the wind is added to the temperature. Wind moves heat away from the body so that it feels colder. Inform students that the winds in Antarctica can be dangerously strong and that they can last for days. The harsh winds are called katabatic winds. They are found in other places in the world but never as strong as they are in Antarctica.
Katabatic winds originate in the interior of the continent.
They are formed because of the domed shape of Antarctica. This is as windy as a hurricane. The winds are much calmer in the interior of the country. Ask students for reasons that the winds are dangerous. The force of the winds can injure humans or animals.
