Snow and Snowflakes - Met Office
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.
