TL;DR

Hail is formed when updrafts lift water droplets in a thunderstorm cloud and freeze them into hailstones, snowflakes form when ice crystals grow branches as they fall through the atmosphere, and snow appears white because it reflects all colors of light equally.

It's AumSum Time. What is hail? A burger rain. No. Hail is a type of rain in which balls of ice called hailstones fall from sky. But, for the hail formation, following conditions are necessary. Firstly, there must be a thunderstorm cloud. Secondly, the upper portion of the cloud should be below freezing temperature. Thirdly, the cloud should have a... Read More

Key Insights

• 😶‍🌫️ Hail is formed in thunderstorm clouds through a process involving updrafts, freezing temperatures, and the accumulation of water on ice.
• 🥶 Snowflakes form their intricate, symmetrical shapes as ice crystals fall through the atmosphere and collect more water, causing branches to grow on the corners.
• 🙂 The color of snow appears white because it reflects all colors of light equally, as it does not absorb any colors.
• 👃 The prediction of rain can be based on the smell of ozone produced by lightning or the smell of aromatic particles released when raindrops hit surfaces.
• 🛝 Snowflakes are unique due to their different paths to the ground and encounters with varying atmospheric conditions.
• 😶‍🌫️ Hailstones become too heavy for updrafts to hold, resulting in their fall from the cloud as hail.
• 🥶 A combination of atmospheric conditions and the structure of ice crystals determines the shape of snowflakes.

Questions & Answers

Q: How is hail formed?

Hail is formed in thunderstorm clouds when strong updrafts lift water droplets upward, causing them to freeze into ice. As the updrafts push the ice higher, more water freezes onto it, creating larger hailstones. Eventually, the hailstones become too heavy and fall from the cloud as hail.

Q: How do snowflakes form their unique shapes?

Snowflakes form when ice crystals fall through the atmosphere and encounter more water. The water freezes on the corners of the ice crystal, causing branches to grow and giving the snowflake its intricate shape. The growth of the branches is symmetrical due to the consistent atmospheric conditions on all sides of the snowflake.

Q: Why does snow appear white?

Snow appears white because it reflects all colors of light equally. Unlike objects that absorb or reflect certain colors, snow does not absorb any colors and reflects all of them. As a result, when sunlight or white light hits the snow, it is reflected back in its entirety, making the snow appear white.

Q: How can people predict rain?

There are two ways to predict rain. In the first case, just before heavy rainfall, lightning splits nitrogen and oxygen molecules, creating ozone. When strong winds carry ozone downward, its sharp smell helps people predict rain. In the second case, when it is already raining nearby, raindrops hitting surfaces with aromatic particles create air bubbles that rush upwards and burst out. The gusts of wind carry these particles ahead of the rain, allowing people to smell them and predict rain.

Summary & Key Takeaways

• Hail is formed in thunderstorm clouds when updrafts lift water droplets, causing them to freeze into hailstones.

• Snowflakes form when ice crystals fall through the atmosphere and collect more water, growing branches and creating a unique, symmetrical structure.

• Snow appears white because it reflects all colors of light equally, as it does not absorb any colors.
