- 9. Multiple ChoiceSome students made a model to show one of the first steps in the formation of sedimentary rock. The students pour 2 cm of light-colored sand into a clear plastic box.

Sedimentary rock is made of layers.B. Sedimentary rock is cemented bits of rock.C. Sedimentary rock is often limestone.D. Sedimentary rock is common in Texas.

- 12. Multiple ChoiceA student creates a model of the formation of fossil fuels by first placing a layer of leaves, representing organic matter, in the bottom of a cup. What step will come next in the model?A. Pouring water over the leaves to model washing away by rivers.B. adding sand on top of the leaves to model burial in sediments.C. Burning the leaves to model the decay of organic matter.D. Putting the leaves in the freezer to model conditions on top of mountains.
