Two wires carrying electricity can create a spark if they come too close together. This spark can start a fire. Wires carrying electricity are usually covered with plastic to keep them from starting a fire. Why does the plastic keep electricity from starting a fire?

• Mrs. Radke said so.

• It is an insulator.

• It is a conductor.

• All of the Above

Erosion is one of the processes involved in the formation of sedimentary rock. Which of these best describes the process of erosion?

• 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.
