It looks like you've uploaded an image of a diagram titled
"Soil Layers" from EnchantedLearning.com, which shows a cross-section of soil with different layers and a plant growing in it. The diagram includes a vertical column representing the soil profile, with various textures indicating different soil layers, and a blank space on the right side with lines for labeling.
Task:
The task is likely to
label the soil layers shown in the diagram based on their position and characteristics.

Soil Layer Identification (from top to bottom):
1.
Topsoil (A horizon)
- Located at the very top.
- Rich in organic matter (decayed plants and animals).
- Dark in color.
- Supports plant growth — roots are visible here.
- This layer is where most plant roots grow and where nutrients are concentrated.
2.
Subsoil (B horizon)
- Below the topsoil.
- Contains minerals leached from above.
- Often lighter in color than topsoil.
- May have clay or iron deposits.
- Roots may extend into this layer.
3.
Parent Material (C horizon)
- Below the subsoil.
- Consists of partially broken-down rock.
- Less weathered than upper layers.
- Minerals begin to form here.
4.
Bedrock (R horizon)
- The solid rock layer beneath all soil.
- Not soil, but the source material for soil formation.
- Roots can't penetrate this layer.

How to Label the Diagram:
On the right side of the diagram, write the names of the layers
from top to bottom, matching them with the corresponding section in the soil column:
1.
Topsoil (A horizon)
2.
Subsoil (B horizon)
3.
Parent Material (C horizon)
4.
Bedrock (R horizon)
> Note: Some diagrams may combine or simplify layers. If there are only 3 labeled lines, you might see: Topsoil, Subsoil, Bedrock (with parent material grouped with bedrock).

Additional Notes:
- The plant’s roots extend through the topsoil and into the subsoil.
- The surface has litter (dead leaves and plant debris), which decomposes and becomes part of the topsoil.
- The diagram is educational and often used in science classes to teach about soil profiles.

✔ Final Answer:
Label the soil layers from top to bottom as:
1.
Topsoil
2.
Subsoil
3.
Parent Material
4.
Bedrock
This completes the labeling task for the soil layers diagram.
