Is Q-Inherent Soil Quality
SQS-Soil Quality Standards
Climate is defined as the average weather pattern over a long period of
time at a particular location, normally in terms of temperature and
Weather is not the climate, climate is long term trends
Climate is not the same everywhere. Why? There are two fundamental
abiotic reasons why
1) The Earth is round (non-equal distribution)
2) Tilted on its axis (unequal amounts of sunlight)
Hadley Cell –30 digress North/South of equator
Cycle that creates heavy rainfall near equator, and the leftover cool
air at sucks up all moisture at 30 degrees
Polar Cell – 60 degree/cool dry air sent over the artic (cycle)
The polar cell and Hadley cell interact and create what is known as the
temperate zone (Ferrel cell) (30-60 degrees = creates our temperate
Coriolis Force: objects/winds deflect to the right in northern hemisphere and
to the left in southern hemisphere
World Biomes are affected by participation and temperature
Both alive and inert, soil chemistry drives activity.
Each subsequent level of soil is called a horizon
O horizon: Organic layer freshly fallen organic material - most
A horizon: Mixture of organic matter, minerals, clay, silt and/or
B horizon: Clay, humus, and other materials leached from A horizon
- often contains plant roots.
C horizon: Weathered “parent” material. (rock bed, (no soil and
E.g. of soils in Canada
Podzolic soils in Boreal regions
Chernozemic soil: dark areas are the organic layers Processes which re-distribute soil are: wind and water are two main abiotic
processes that move soil around.
C. Biome: 3 definitions that can be found
• A large, relatively distinct terrestrial region, encompassing many
interacting ecosystems, and characterized by similar climate, soil, plants,
and animals, regardless of where it occurs on Earth.
• A biogeographic region; a major regional ecological community
characterized by distinctive life forms and principal plant (terrestrial biome)
and animal (marine biome) species.
• A major life zone containing interrelated plants and animals adapted to a
particular climate and soil, which covers a large geographical area.
There are many different Terrestrial Eco-zones within a Biome.
Terrestrial biomes is a variety of habitats, not just one (patches of
Artic tundra: short growing season with little participation
Boreal Forest: dominated by black spruce trees, acidic soil limits
tree variation. S
