Which answer choice correctly matches the horizon name with its composition?
E Horizon - This is called the bedrock layer. This is the parent material for the soil.
C Horizon - This layer contains some mineral components with a large amount of organic material.
O Horizon - This layer is mostly settled clay. Since clay is the soil texture with the smallest size, this lays directly above bedrock.
A Horizon - This is called the topsoil. This is where seeds germinate, and worms and nematodes are likely to live.
B Horizon - This is called the organic layer. This is where dead leaves and other detritus accumulate and form a nutrient rich layer. This incorporates into the soil as substances are broken down through decomposition and are carried into the soil.
