Explanation:

To solve these questions about soil formation, we refer to concepts in Earth Science (a subfield of Natural Science, specifically Geography or Environmental Sciences, related to soil horizons and soil properties):

Question 1 (True/False - Modify if False)

Statement: Another name for the B horizon is topsoil.

• The A horizon is called topsoil. The B horizon is also called the subsoil. So we change “topsoil” to “subsoil”.

Question 2 (True/False - Modify if False)

Statement: Soil that is rich in humus generally has fine texture.

• Humus-rich soil (like topsoil) often has a fine texture (e.g., loam). If the original statement was marked, but based on soil science, humus-rich soil (e.g., A horizon) typically has fine texture, so this may be true (or adjust if the underlined word was incorrect; assuming “fine” is correct, it’s true).

Question 3 (True/False - Modify if False)

Statement: Subsoil is the solid layer of rock beneath soil.

• The solid rock layer beneath soil is bedrock (R horizon). So change “subsoil” to “bedrock”.

Question 4 (True/False - Modify if False)

Statement: Soil texture depends on the size of rock particles in soil.

• Soil texture is defined by the size of mineral (rock) particles (sand, silt, clay). This is true.

Question 5 (True/False - Modify if False)

Statement: The E horizon consists of weathered bedrock.

• The E horizon is an eluviated layer (leached), while weathered bedrock is in the C horizon (or R horizon). So change “E” to “C” (or “R” for bedrock, but C is weathered bedrock/parent material).

Question 6 (True/False - Modify if False)

Statement: You can use the pH scale to measure how acidic a soil is.

• The pH scale measures acidity/alkalinity. This is true.

Question 7 (Multiple Choice - Which soil layer contains little humus?)

• The B horizon (subsoil) or E horizon has little humus (A horizon has the most humus). Typically, the B horizon (subsoil) or C horizon has less humus. If options were (e.g., B, C, E), the answer is likely the B or E horizon (e.g., B horizon has little humus compared to A).

For each question, we apply soil science concepts (from Geography/Environmental Sciences, subfield of Natural Science) to identify true/false and correct terms.

Final Answers (Sample for Each):

1. Change “topsoil” to subsoil
2. (If true) True; (if false, adjust, but likely True)
3. Change “subsoil” to bedrock
4. True
5. Change “E” to C (or “R” for bedrock)
6. True
7. (E.g., if options: B. B horizon, then B. B horizon)
