Alexa created a model and chart of a soil horizon to present to her science class.

Layer Descriptions

O: dark layer made of living and decomposing materials.

A: dark layer made of minerals and decomposed materials; contains humus

B: light layer made of minerals, clay, and organic material

C: light layer made of rock and a small amount of organic material

Which statement best explains a mistake in Alexa's presentation?

• Layer O should not have any living materials.

• Layer A should be a light color from the humus.

• Layer B should be darker because of the clay.

• Layer C should not contain grass roots.
