Question

students from a high school science class visited the desert of southern california and investigated a sample of sedimentary rock from the region. which question can they answer through scientific investigation? which fossils are found in different layers of sedimentary rock? why are sedimentary rocks prettier than other kinds of rocks? which layers of a sedimentary rock have the most interesting fossils? why should scientists study sedimentary rocks?

Explanation:

• "Which fossils are found in different layers of sedimentary rock?" is a scientific question. It can be investigated by examining the rock layers, using techniques like stratigraphy and fossil identification.
• "Why are sedimentary rocks prettier than other kinds of rocks?" is a subjective question as "prettier" is based on personal opinion and not measurable or testable in a scientific way.
• "Which layers of a sedimentary rock have the most interesting fossils?" is subjective. "Most interesting" is a matter of personal preference and not an objective, scientific criterion.
• "Why should scientists study sedimentary rocks?" is more of a philosophical or value - based question rather than a question that can be directly answered through a hands - on scientific investigation of the rock sample.

Answer:

Which fossils are found in different layers of sedimentary rock?
