Sedimentary rocks form when broken bits of other rock are deposited and then –

• buried and squeezed and cemented together

• melted by the heat of the Earth’s core

• completely dissolved in salt water in the ocean

• used by humans as a natural resource

Reorder the following steps in the formation of sedimentary rock

• The sediment is buried and pressure pushes down on it.

• The sediment is glued together forming one rock.

• Sediment is dropped off by wind, water, or ice.

• Rock is broken down into sediment by wind, water, or ice.

• Sediment is carried by wind, water, or ice.

The model shows layers of sediment on the floor of an ocean. Which of the following best explains how these layers can become rock over many years? (5.7A)

• Sand in the sediment melts and turns into rock.

• The weight of the water compacts the sediment into rock.

• Changing water temperatures turn sand in the sediment into rock.

• Pollution caused by humans turns the sediment into rock.

Fossil fuels formed over long periods of time after particles in water settled to the sea floor and formed marine mud. What kinds of particles needed to be present in the marine mud in order for fossil fuels to form? (5.7A)

• Mostly sand and a few small bits of wood

• Mostly decaying organisms

• Mostly lava and a few sedimentary rocks

• Mostly metal minerals

Some students make a model to show one of the first steps in the formation of sedimentary rock. The students pour 2 centimeters of light-colored sand into a clear plastic box. Then they add 1 centimeter of gravel. Finally they pour 2 centimeters of dark-colored sand on top of the gravel. Which characteristic of sedimentary rock does this model best show? (5.7A)

• Sedimentary rock is made of layers.

• Sedimentary rock is cemented bits of rock.

• Sedimentary rock is often limestone.

• Sedimentary rock is common in Texas.

Erosion is one of the processes involved in the formation of sedimentary rocks. Which of these best describes the process of erosion? (5.7A)

• Rocks are broken into smaller pieces that remain in the same location.

• Pressure compacts layers of sediment and turns them into rock.

• Pieces of rock or soil are carried from one place to another.

• Sediment grains fall to the bottom of a lake to form sedimentary layers.
