Some Common Types of Fog. The most common form of fog, known as radiation fog, typically occurs on clear nights as the earth's surface cools moist air immediately above it.

A cryptocurrency is a digital or virtual currency designed to work as a medium of exchange. It uses cryptography to secure and verify transactions as well as to control the creation of new units of a particular cryptocurrency.
Crypto, the prefix in both words, comes from the Greek word kruptos, which means âsecret.â Cryptocurrencies incorporate many of the technologies and theories developed by cryptographers in order to create a digital money exchange system that is resistant to both censorship and fraud.
