Question

Soil horizons are defined by physical features. true or false?

Answer 1

The answer is True. A soil horizon is a cross-section of the physical layers that make up the soil. The soil horizons include such features as the organic layer, surface layer, subsoil, substratum and bedrock. Each horizon is unique and different depending on the land it is found on.

Answer 2

The statement “soil horizons are defined by physical features” is TRUE.

Further Explanation:

A soil horizon is a layer which is parallel to the “soil surface”, whose physical feature varies from the layers “above” and “beneath”. Every soil type has a minimum one, usually ‘three’ or ‘four’ horizons. Horizons can be defined in most of the cases by obvious physical characteristics, chiefly texture and color. This can be described both in “absolute terms” (for example, particle size distribution) and in “relative terms” to the ‘surrounding material” i.e. ‘Sandler’ or ‘coarser’ than the horizons ‘above’ and ‘below’.

Description and identification of the ‘horizons’ present at given ‘site’ is the initial step in the classification of soil at higher levels, by the use of systems like “USDA soil taxonomy” or the “Australian Soil Classification”.
