Answers
Answer:
c. C- horizon
Explanation:
hope it's helpful for you
A- horizon is right answer
A (topsoil): Mostly minerals from parent material with organic matter incorporated. A good material for plants and other organisms to live.
E (eluviated): Leached of clay, minerals, and organic matter, leaving a concentration of sand and silt particles of quartz or other resistant materials – missing in some soils but often found in older soils and forest soils.
B (subsoil): Rich in minerals that leached (moved down) from the A or E horizons and accumulated here.
C (parent material): The deposit at Earth’s surface from which the soil developed.
R (bedrock): A mass of rock such as granite, basalt, quartzite, limestone or sandstone that forms the parent material for some soils – if the bedrock is close enough to the surface to weather. This is not soil and is located under the C horizon.
