It is a loose covering of broken rock particles and decaying organic matter.
It forms from the surface downward toward the parent rock.
Living organisms add nutrients to it.
It takes a long time to form.

Answer 1

Answer:

It forms from the surface downward toward the parent rock.

Explanation:

A typical soil does not form from the surface downward toward the parent rock.

Soil is formed by the weathering of the parent rock. During weathering, a rock is broken down into smaller fragments by chemical and physical means.

• From the bedrock, as the disintegration proceeds, fine particles of earth are formed.
• This in turn gets mixed with organic matter, water and air to form a full soil profile.
• Soil takes a very long time to form.
