Use the information below to answer the following question.
A teacher gave students four rock samples. The students listed their observations about each rock sample in the data table below.
Which of these statements best explains why the edges of Rock 4 are smooth?
3.
The diagram below shows the rock cycle.
Which conclusion is best supported by the diagram?
4.
Your teacher has brought a sample of water to class. The sample contains a mixture of small rocks, sand, and silt (very
fine soil) from the Mississippi River. After a few hours, the sample settles. Which diagram shows how the sample will settle?

14. Index fossils help scientists estimate the age of a rock because index fossil species only existed for a relatively short time. What
happened to the species that are now used as index fossils?

27. Where an oceanic plate collides with a continental plate, why does the oceanic crust get pulled under the continental crust?
28. Why do earthquakes occur at subduction zones?
29. In transform boundaries, the plates can become “stuck.” What happens when the plates suddenly become “unstuck”?
