The Science Behind Snowflakes and Snow


❄️ What is Snow?

Snow is frozen water that falls from the sky when the air is very cold.

👉 Snow is made of ice crystals, not raindrops.


🌬️ Step 1: Water goes up into the air

  • Water from rivers, lakes, and oceans evaporates (turns into invisible water vapor)
  • The vapor rises into the sky

☁️ Step 2: Clouds form

  • High in the sky, air is cold
  • Water vapor cools down and forms tiny water drops or ice crystals
  • These collect together to make clouds

❄️ Step 3: Why snow forms instead of rain

Snow forms when:

  • The temperature in the cloud is below 0°C (32°F)
  • Water vapor freezes directly into ice crystals

👉 Instead of becoming liquid rain, it becomes solid ice


❄️ Step 4: Snowflakes grow

  • Tiny ice crystals stick together
  • They grow into snowflakes
  • Each snowflake has a special shape

🌟 No two snowflakes are exactly the same!


🌨️ Step 5: Snow falls to the ground

  • When snowflakes get heavy enough
  • Gravity pulls them down to Earth
  • If the air stays cold, they reach the ground as snow

If the air becomes warm:

  • Snow melts → rain or sleet

🧊 Why snow is white?

Snow looks white because:

  • Snowflakes have many flat surfaces
  • They reflect light
  • All colors of light together look white

🧠 Simple science summary

🌬️ Water vapor rises
☁️ Freezes in cold clouds
❄️ Forms ice crystals
🌨️ Falls as snow


🌟 Fun snow facts

  • Snowflakes grow inside clouds
  • Snow helps keep the ground warm like a blanket
  • Fresh snow makes places quiet

🎯 Easy to remember

Very cold clouds + water vapor = snow
