This image is called.....

• A soil horizon

• A soil profile

• A soil pit

• A soil sample

Which of these is not a function of soil?

• Base for construction
• Habitat for soil organisms
• Support plant growth
• Something which chemically weathers parent rock

Which of these is a correct definition of the A horizon?

• A layer of partially decomposed organic matter
• A layer of unweathered parent rock material
• Mineral matter mixed with some organic matter
• A zone of illuviation

The finest soil particles are known as -

(HINT: They trap & hold nutrients ... sometimes out of plants' roots' reach)

• silt

• clay

• loam

• sand

The most productive soil type is

• sandy soil

• clay soil

• loam soil

• silty clay loam

soil flows include (choose all that apply)

• weathering

• decomposition

• leaching

• organic matter

• biological mixing

The A soil horizon (topsoil) is made up of

• leaf litter

• bedrock

• clay and minerals

• decomposed organic matter and minerals

Weathering is a process where

• organic matter is broken down into smaller parts, usually by living organisms

• rock is broken down into soil and small grains

• soluble nutrients and minerals are drained from soil through water action

• soil/rock is moved from one surface to another by wind/water/glaciers
