Summarize this article for a 10 year old
In physics and chemistry, flash freezing is the process whereby objects are rapidly frozen.[1] This is done by subjecting them to cryogenic temperatures, or it can be done through direct contact with liquid nitrogen at −196 °C (−320.8 °F). It is commonly used in the food industry.

Flash freezing is of great importance in atmospheric science, as its study is necessary for a proper climate model for the formation of ice clouds in the upper troposphere, which effectively scatter incoming solar radiation and prevent Earth from becoming overheated by the sun.[2]
The process is also closely related to classical nucleation theory, which helps in understanding many materials, phenomena, and theories in related situations.
