Snow is made of tiny ice crystals that form unique snowflake shapes. The word "snow" originated from the Old English word "sniwan" over 700 years ago. For snow to settle and accumulate on the ground, the temperature needs to be 3 degrees Celsius or lower. Avalanches occur when a heavy slab of accumulated snow slides down a sloped mountainside, often after a large snowstorm. Snow and hail are different, as snow is made of ice crystals while hail is frozen raindrops. As more snow falls and freezes on top of existing snow, it turns the snow into ice.
2. What is snow?
Snow is made up of one or more tiny ice crystals that
come together to form the unique shapes of a
snowflake
3. Why is snow called snow?
The word "snow" traces back 700 years to the
year 1300.
It comes from word "sniwan", which then
became "snew", then “snaw” and now we
call it snow
4. How many degrees does it take for
snow to settle?
It needs to be 3 degrees celcius to settle.
5. Why does snow avalanche?
• An avalanche happens when a big slab of snow slides
down sloping terrain. Each snowstorm adds new layers of
snow and if the weight of the snow gets too heavy it
causes the slab of snow to slide down the mountain
slope. Most avalanches occur after a big snowstorm.
6. Are snow and hail the same?
• No - Snow is made from ice crystals
• Hail is a frozen raindrop and is a lot bigger than
an ice crystal
7. How does snow turn to ice?
• More snow falls on other snow and then it
freezes and makes ice.
8. Having fun in the Snow
• When it snows I like to:
– Make snowmen
– Make snowballs
– Go snowboarding
– Go sledding
– Eat the snow
– Make snow angels
– Make yellow snow
