Question

Particles of soil often differ greatly from the underlying bedrock in color, mineral compoition, and organic content. Which conclusion about these soil particles is best made from this evidence?

Answer 1

Let's go through the options: 1 They are residual sediments. No, since the information says they're different in color, mineral composition, and organic content. [ The bedrock would have to be the same if the soil was a residual sediment. 2 They are transported sediment. This seems reasonable. If the sediment is not the same type as the rock, it would have had to come from somewhere else. 3 They are uniformly large-grained. Maybe, but it doesn't say anything about it. 4 They are soluble in water. Again maybe, because it doesn't say anything about it. If you think carefully through each option in questions like these, you can usually think through to what things make the most sense.

Answer 2

They are transported sediments.

Step-by-step explanation:

A solid and very hard stone is called a rock. Geology defines rocks as linked solids that are formed by one or more minerals. The notion of a mother, on the other hand, refers to a female who gave birth or the origin of something. The idea of parent rock therefore evokes what defines and defines the mineral matrix of a soil. In other words, the parent rock is the type of rock on which the soil is supported. Through erosion and a weathering process, the parent rock allows the development of the inorganic sector of the land in question.

However, it is common for the soil to be different from the rock that originated it. This difference can be seen in color, mineral composition and organic content. This is because they are transported sediments.
