Soil cover's most of the world's land and we need it to grow plants for food.

Soil is made from: worn down rock, humus (dead and rotting material), air and water.

Soil is full of life:
  • worms, insects and termites eat, live and die in the soil;
  • microbes like bacteria break down dead plants and animals.

The properties of a soil depend on what kind of worn dock rock it comes from:

  • sandy soil is pale coloured, usually feels dry and has few nutrients in it;

  • clay soil is orange coloured, is very sticky when wet, has few air gaps and gets waterlogged easily;
Standing water - geograph.org.uk - 1608755
  • peat soil is mostly made from decayed plants, is dark and crumbly and is rich in nutrients (chemicals that plants need to grow).
