Snow is formed when temperatures are low and there is moisture in the atmosphere in the form of tiny ice crystals. When these tiny ice crystals collide they stick together in clouds to become snowflakes. If enough ice crystals stick together, they'll become heavy enough to fall to the ground.

The difference between sleet and hail is that sleet is usually smaller and form in stratus clouds. The video said sleet is usually smaller and are sometimes called ice pellets.They form in stratus clouds snowflakes start to melt as they fall. Then, they refreeze into small pellets. Hail is a shower of round or irregular shaped ice particles which form in a cumulonimbus cloud. They start as ice particles caught in a updraft of air in the cloud. When they ascend they gather water, growing. When the hail gets too heavy for the updraft, it falls to the ground. Some hailstones can be 6 inches in diameter.

This was really cool. I learned a lot about snow. First off, snow forms when temperatures drop below freezing. They start off as snow crystals, then either collide with more water droplets or other crystals to form the different kinds of snow we see. That might be tthe reason you go outside looking for perfect, pretty snow flakes, when that all happened in a cloud! Sorry you missed it! The PWI is a high speed camera that allows people to capture photos of snow flakes that are accurate. This will allow meteorologists to predict when the snow is falling, but now, exactly what type of snow is falling. Grauple, Aggregate, ice, sleet, or rain. This is the future of snowflake photographers.

I learned that snowflakes are created when snow crystals find some thing to hold onto like a grain of sand and then combines with other snow crystals to become a snowflake.

I learned a lot from this video about snow. I learned that snow needs to form at least at the temperature of 0 degrees Celsius. Also, when it is colder the snowflakes will be larger. They need tiny particles to hold onto as they form such as dirt. Hail is different from sleet because sleet is smaller than hail. Hail forms when snowflakes freeze while falling from the cloud so they become little balls of ice. While hail instead of falling right down will get caught in an updraft and will be carried back up through the clouds. The size of the hail depends on how much moisture is in the cloud and how many times it goes through the cloud. Every time it goes through the cloud it will get another layer of ice. This keeps on happening. As a result, some hail can have a diameter of 6 feet! That hail must be very destructed and can make things break into fragments. This is what I learned from this video, and next time I'll know what's happening in the clouds when it's snowing.
