Question

1. ______ the c horizon consists of weathered bedrock. p.165
2. ______you can use the ph scale to measure how acidic a soil is. p.164

Explanation:

It seems these are fill - in - the - blank or true - false (with possible correction) questions related to soil science, which falls under the subfield of Geography (in Natural Science) or Environmental Sciences (also in Natural Science). Let's analyze each:

Question 5

The statement "The C horizon consists of weathered bedrock" is a factual statement about soil horizons. If this is a true - false or a fill - in - the - blank to confirm the statement, the correct term related to the description of the C horizon being weathered bedrock is just confirming the statement. If it's a fill - in to state if it's true (maybe a T for true), but looking at the handwritten part, maybe it's a true statement.

Question 6

The statement "You can use the pH scale to measure how acidic a soil is" is correct because the pH scale measures the acidity or alkalinity (basicity) of a substance, including soil.

If we assume these are true - false questions where we mark T for true:

For question 5: The statement is true (T) as the C horizon in soil profile is made of weathered bedrock.

For question 6: The statement is true (T) as pH scale is used to measure acidity (and alkalinity) of soil.

But if the original questions were to fill in the correct term (maybe "True" or the correct concept), for question 5, the C horizon's composition is weathered bedrock, so the answer related to the statement's validity is that it's true. For question 6, using pH to measure soil acidity is true.

If we follow the handwritten style (maybe filling in "T" for true):

Question 5: T (since C horizon has weathered bedrock)

Question 6: T (since pH measures soil acidity)
