WebAug 6, 2024 · Sphere to Hamburger Bun. When the drop is small (under 1 mm across), surface tension wins out and pulls it into a spherical shape. But as the drop falls, colliding with other drops as it does so, it grows in size and it falls faster which increases the pressure on its bottom. This added pressure causes the raindrop to flatten on the bottom. WebDec 10, 2024 · Snowflakes can only form when the temperature reaches 0°C – the freezing point of water molecules.

WebSnowflakes can only form when the temperature reaches 0°C – the freezing point of water molecules. That doesn’t mean that it will always snow when it is 0°C, since there are other atmospheric conditions that have to be met to guarantee there will be snow, such as humidity, moisture, wind, etc. WebIn the model following assumptions are used: (1) Snowflakes are spherical and have ice skeleton structure incollapsable until the com- pletion of melting. (2) Melting takes place at snowflake surface and water produced by melting on the surface penetrates into the inside. The water does not
