Cryptozoology is a pseudoscience and subculture that aims to prove the existence of entities from the folklore record, such as Bigfoot, chupacabras, or Mokele-mbembe. Cryptozoologists refer to these entities as cryptids, a term coined by the subculture. Because it does not follow the scientific method, cryptozoology is considered a pseudoscience by the academic world: it is neither a branch of zoology nor folkloristics.

Explanation: Nucleation can be described as the process that determines how long an observer has to wait before a new phase occurs,such as the conversion from liquid to gas or vapour or from Solid to liquid.
There are basically two types of Nucleation which includes the HOMOGENEOUS NUCLEATION AND THE HETEROGENEOUS NUCLEATION.
Homogeneous nucleation(nucleation that occurs in the absence of foreign particles) is a type of Nucleation that requires more undercooling than Heterogeneous nucleation, they occur below the freezing temperatures.
Heterogeneous Nucleation (a type of Nucleation that occurs in the presence of foreign particles), it usually takes place at the surface and they usually require less undercooling temperature than Homogeneous nucleation.
