Soil or Rock in which part or all of the pore water has turned into ice. Frozen ground occurs when the ground contains water, and the temperature of the ground goes down below Celsius (32° Fahrenheit). It can make a big difference if the ground stays frozen all year, or if the ground freezes and thaws. More than half of all the land in the Northern Hemisphere freezes and thaws every year, and is called seasonally frozen ground. One-fourth of the land in the Northern Hemisphere has an underground layer that stays frozen all year long. Ground that stays frozen for at least two years in a row is called permafrost.
