- Permafrost - Permanently frozen ground, found in polar and tundra regions.
- Polar - The regions of Earth surrounding the North and South Poles.
- Tundra - The flat, treeless Arctic regions of Europe, Asia and North America, where the ground is permanently frozen.
Considering this, what are the characteristics of soils in cold environments?
Permafrost may extend up to 450m below the ground. The soil is rich in nutrients because it is too cold for organisms to decompose. Climate – Tundra environments are cold, windy and have little precipitation. Precipitation falls as snow in winter and as rain during the brief summer.
Likewise, how are plants adapted to cold environments? Adaptations. Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Plants may hold onto dead leaves for insulation, or use deep snow like a blanket to protect against the cold.
Besides, what is a cold environment?
Cold environments are characterised by low temperatures but are varied in their nature. They cover approximately 25% of the world's land surface. Defining a cold environment is not always precise as some cold environments are permanently cold whereas others are seasonally cold, warming up in the summer months.
Why are cold environments fragile?
Small number of species and slow growth rate- Population numbers vary greatly. Large oscillations provide polar and artic ecosystems with resilience and can survive change – eg Climate change.
