Learn when snowfall happens and how snow forms in this fun video for kids.

Transcript

00:00 Snow usually falls in winter, when it is very cold.

00:04 It forms when the temperature is below 0 degrees Celsius,

00:10 also known as the freezing point of water.

00:15 This causes very small drops of water in the air to freeze into ice crystals.

00:23 And when these ice crystals bump into one another,

00:26 they stick together and form snowflakes.

00:30 It can take a long time for a snowflake to fall from a cloud to the ground,

00:34 because they are so light.

00:36 The journey could take one hour.

00:39 If the ground is cold enough when snowflakes fall,

00:43 they stick and don't melt.

00:45 We say the snow has settled.

00:48 A covering of snow can make everything look white and bright.

00:52 A blizzard occurs when lots of snowflakes fall during a time of strong winds.

00:58 It can be difficult to see between the snowflakes,

01:01 so it's best to stay inside during a blizzard.

01:04 We are able to measure how much snow is lying on the ground using a ruler.

01:10 The deepest snow ever recorded in the UK

01:14 was an enormous 1 metre and 65 centimetres deep.

01:20 It fell in North Wales during the very snowy winter of 1947.

01:27 To measure that, we'd need a very long ruler.
