How do ice crystals form in a cloud?

Answer 1

When a liquid hits it's freezing point (0 Degrees Celsius) the liquid atoms start to crystallize and expand. Thus, creating ice! when the ice melts, the atoms separate again and decrease in size. Thus, liquid! There you go!

Answer 2

Ice crystals form in a cloud when water vapor in the air freezes onto microscopic particles known as cloud condensation nuclei. These ice crystals grow in size as they collide with one another and become heavy enough to fall as snow or rain. Temperature and humidity levels in the cloud play a significant role in determining the formation of ice crystals.

Answer 3

Just as liquid cloud droplets form on condensation nuclei, ice crystals may form in subfreezing air on particles called ice-nuclei.

Also, in a cold cloud, there may be several types of ice-forming nuclei present.

For example, certain ice nuclei allow water vapor to deposit as ice directly onto their surfaces in cold, saturated air. These are called deposition nuclei because, in this situation, water vapor changes directly into ice without going through the liquid phase. Ice nuclei that promote the freezing of supercooled liquid droplets are called freezing nuclei.

The last process is called contact freezing, and the particles involved are called contact nuclei. Studies suggest that contact freezing may be the dominant force in the production of ice crystals in some clouds.

Answer 4

Liquid water, placed in an ice-cube tray, will form into ice cubes when you freeze it. The freezing process involves water molecules which, as they slow down, bond to each other and form a crystalline solid.

Answer 5

The ice forms by putting a liquid to a freezer for some hours, turns to a solid and that's how it forms.

Answer 6

From large drops of water at freezing temperatures that cause hail and also freezing separated mist into snow.

Answer 7

Clouy ice is formed when air molecules mixed with water molecules so that some defect is formed in water molecules which lead to color change(or cloudy ice formation.)

Answer 8

Crystal clear ice forms by cooling the water after you boil it. You must have constant agitation of the water to produce clear water and prevent bubbles.
