Soils And Application Flashcards
Soils
-Frost heave
-Atmosphere, geosphere and biosphere
-Inputs and outputs
-geomorphic system
-Rapidly lost
-Formed in layers
-Chemical and biological weathering is low
-Physical weathering is high
-Cryohydration
Tundra soils
-Lichen
-Mosses
-Dwarf shrubs
-Grasses
-Freeze-thaw in summer
Permafrost soils
-Top soil in winter -> -10°C
-Ice lenses
-Pingos
Artic vegetation
-1700 species of plants
-Lichen + mosses
-Shallow rooted plants
Antarctic vegetation
-500 plant species
Cold environment vegetation
-Shallow/ / if any roots or stems
-Perenials (no seeds) -> asexual reproduction
-Can still photosynthesise in low temperatures
-Small leaves
Permafrost
Frozen ground which remains frozen all year round for at least 2 consecutive years
