This simulation contains rock layers and fossils from several different locations. Examine the fossils and rock features of each layer. Arrange the rock layers in the correct order, from the oldest at the bottom to the youngest at the top. Rock layers from different locations but the same age should be placed next to each other in the same layer. Once a fossil disappears, it’s gone from the fossil record and does not reappear. Take a screenshot of your results to include in your Lab Report.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
