5.1 Soil systems review

What percent of the soil is minerals and nutrients?

• 5%

• 25%

• 45%

• 50%

Soil texture is the look and feel of the soil and is linked to the proportion of                 , silt and clay particles.

Using the soil triangle below state what type of soil has 33% clay, 43% silt and 24% sand. (N.b do not assume the arrows drawn in red, yellow and blue relate to this soil). 

Soil may be compared to an open system as it exchanges both matter and energy with the surroundings. Choose the sequence which lists soil storages.

• Water, air, organic matter, organisms, nutrients and minerals

• Air, water, nutrients and minerals, horizons, leaf litter

• Precipitation, water, nutrients and minerals, parent material, plants

• Organisms, weathering, leaching, decomposition, water
