Biomes
Landscape is northern areas, open landscape, streams
Climate is cold, dry, short summers
Tundra Biome
Rising moist air masses generate rain ansd moist climates
Decending dry air masses create dry climates
What are precipitation patterns?
Complex ecological systems, mix of living and non-living material where most terrestrial life depends on.
What is Soil?
What is Climatic Variation?
Soil is most fertile in decidous area with nuetral pH, rich in organic matter and nutrients
Biology is vertically stratified forest, vast fungi and bacteria to recycle nutrients, mice to bears
Temporate Biome
Landscape is norhern hemisphere, dense coniferous forest, grassland in south
Climate is long cold winter, minimal evaporation
Boreal Forest Biome
Seasonal variation in temperature/precipitaion
Length and intensity of wet and dry seasons
Portion of year when average minimum temperature is above and below 0degrees
What is summary of climate info?
What is displayed on a climate diagram?
Settlement largly follows resource abundance, modify their environment at larger sclae than any other organism
What are Human Dominated Systems?
Warm air rises, dense cool air takes place. Creates loops of air
What are Convention Currents?
Soil is fertile soil is deep, nuetral pH, lots of oragnic matter, black prarie soils most fertile
Biology is trees and shrubs at streams and rivers, 80% of biomass underground, large herbivors
Grassland Biome
Landscape is both deciduous and coniferous trees,old growth
Climate is moist growing season, average winter
Agricultural Ecosystems
Hydrological cycles disrupted causing droughts and water shortages.
Rising permafrost temperatures, increased rate of decomposition and release of 02
Agriculture development leaves grasslands the most endangered biome
Etc.
What are Human Impacts on Biomes?
The changes are driven by regular shifts in the lattitudes at which the sun is directly overhead
What drives the changes associated with the seasons?
Soil is peat/humus and permafrost
Biology is herbacous plants (grass, moss) caribou, musk-ox, mosquitos, migratory species
Tundra Biome
Landscape is largest biome, dier, grassland, can experience droughts
Climate is most precipitation during summer growing season, can be year-long droughts
Grassland Biome
Winters with low average temperatures and shorter days and summers with high average temperatures and longer days
What do seaonal shifts in solar energy produce at high lattitudes of both hemispheres?
Creates prevailling wind patterns as earth rotates west to east dragging air cells with it
What is the Coriolis Effect?
Thermal loops created by air convection movement confined by specific lattitudes
What are cells?
Soil is thin, acidic, fertility increases as lowered, low temp and pH - slow decomposition
Biology is plants adapted to cold winters and low nutrients, bogs and fens, moose, wolves, bears
Boreal Forest Biome
