Transcript Soil and Biomes

SOIL
What is soil:
Soil:
is a complex mixture of
inorganic minerals, decaying
organic matter, water, air, and
living organisms
How is soil produced?
Produced
by a process called
weathering, which breaks
down rocks via erosion and
decomposition
Layers of Soil
 Topsoil:
uppermost layer that
consists of twigs, leaves, insects,
etc
 Subsoil: consists of rock particles
and minerals
 Weather Rock: made of bits of
rock broken (bedrock)
How Does Soil Differ?
Differs
according to mineral
content, pH, organic content,
etc.
Differs according to location or
biome that it is found in.
BIOME
What is a biome?
Large
geographic area that
has a particular climate, native
animals and plants, etc
Either terrestrial or aquatic
Terrestrial Biomes
 Tropical
Rain Forest
 Grassland (prairies)
 Tundra
 Savanna
 Desert
 Coniferous Forest (or Taiga)
 Deciduous Biome (our biome)
Aquatic Biomes
 Freshwater
(lakes, ponds, streams, etc)
 Marine (oceans)
10% Law
 Used
to determine how much energy is
present in different trophic levels of a food
chain
Where are the biomes located??
 You
will be given a blank map of the world
and different locations for each biome.
Color code each biome to its
corresponding location- hand it at the end
of the period.
