Definition

A vast, treeless biome found in Arctic regions characterized by permanently frozen subsoil (permafrost), low temperatures, and sparse vegetation including mosses, lichens, and small shrubs. Tundra regions support unique wildlife adapted to extreme cold.

Example Usage

The Siberian tundra is one of Earth's most extreme environments, yet it's home to millions of migrating birds each summer.

Origin

From Sámi (Scandinavian indigenous language) 'tunturi,' meaning 'fell' or 'treeless mountain'; adopted into English via Russian.

Fun Fact

The Arctic tundra is melting due to climate change, releasing vast amounts of previously frozen methane and carbon dioxide into the atmosphere.
