Which describe the horizons in a soil profile? check all that apply. horizon a is mineral deficient. bedrock lies below the soil layers. horizon o forms from organic material. horizon b undergoes the least amount of change. horizon c is least affected by the soil formation process.

 correct options are Bedrock lies below the soil layers, Horizon O forms from organic material and Horizon C is least affected by the soil formation process.

Soil profile is a vertical section of the soil that is exposed by digging a hole from the surface of the soil to the underlying bedrock. Most soil profiles are composed of a series of horizons or layers of soil.

O horizon - fallen leaves and partially decomposed organic matter

A horizon - A surface mineral horizon, living organisms, and rock particles.

B horizon - A sub-surface horizon where depletion of organic matter and an accumulation of clay.  

C horizon - A layer of partially altered bedrock

R horizon- Hard bedrock

Bedrock lies below the soil layers.

Horizon O forms from organic material.

Horizon C is least affected by the soil formation process.

These are the correct answers.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
