Answer 1

1. Soil.

2. Soil profile.

3. Regolith.

4. Humus.

5. Soil texture.

6. Soil pH.

7. Inorganic.

8. Soil horizon.

9. Parent material.

10. Organic.

Step-by-step explanation:

1. Soil: the thin upper layer of Earth's crust that supports plant life. There are three (3) main types of soil; sandy, clay and loamy soil.

2. Soil profile: a vertical section of soil that shows the horizon and parent material.

3. Regolith: the layer of loose rock on the surface of the earth; also called mantle rock.

4. Humus: dark colored organic material in soil; it is left over from the decay of living things.

5. Soil texture: a physical property of soil that describes how the soil feels, and the relative components of sand, silt, and clay sized particles.

6. Soil pH: a chemical property of soils that describes the measure of hydrogen ions in a soil sample; how acidic or basic a soil sample is.

7. Inorganic: a substance that does not contain carbon and hydrogen atoms, such as salts, rocks, and minerals.

8. Soil horizon: a distinct layer of soil that has characteristic properties.

9. Parent material: the rock material that was weathered to form the sediments in a given soil.

10. Organic: a substance that contains carbon and hydrogen atoms, such as carbon dioxide, glucose, methane, and nucleic acid.
