KIDS TRIVIA

Detailed explanation-1: -Permafrost is a permanently frozen layer on or under Earth’s surface. It consists of soil, gravel, and sand, usually bound together by ice. Permafrost usually remains at or below 0°C (32ºF) for at least two years. Permafrost can be found on land and below the ocean floor.

Detailed explanation-2: -Permafrost, also known as perennially frozen ground, is generally considered to be a thickness of soil, surficial deposits, or bedrock at a variable depth below the surface of the earth in which the temperature of the matrix has existed below the freezing point of water for a period of at least several years.

Detailed explanation-3: -Tundra biome is located in the far north and is characterized by persistent soil ice (permafrost) throughout the growing season which in turn does not allow growth of any vegetation.

Detailed explanation-4: -When water freezes or when the temperature of soil drops to or below 0°C (32°F) it is known as frozen ground. Permafrost, or permanently frozen ground, is soil, sand, sediment, or rock bound by ice that remains at or below 0°C (32°F) for at least two years.

Detailed explanation-5: -Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink.
