Some 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.  Then they add 1 cm of gravel.  Finally, they pour 2 cm of dark-colored sand on top of the gravel.  Which characteristic of sedimentary rock does this model best show?

• Sedimentary rock is made of layers.
• Sedimentary rock is cemented bits of rock.
• Sedimentary rock is often limestone.
• Sedimentary rock is common in Texas.
