Question

which material is a part of bedrock?
o silt
o plants
o wood
o water

Explanation:

Bedrock is solid rock beneath soil and other loose - overlying materials. Silt is a fine - grained soil particle and can be part of the overlying materials on bedrock, but is not bedrock itself. Plants, wood, and water are not components of bedrock. Bedrock is composed of rock materials. Among the options, none of them are parts of bedrock as bedrock is rock, but if we consider in terms of materials that can be associated with the geological context around bedrock, silt is the closest in the sense that it can be in contact with bedrock in the soil profile.

Answer:

silt
