What is soil
  • Soil is a complex mixture of inorganic minerals,

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.
