Erosion is a process that moves pieces of rock or soil from one place to another. This process most often takes place by water, wind, or ice. Which of the following best describes the process of erosion?

• Potential energy

• Chemical energy

• Kinetic energy

• Elastic energy

Which of the following statements best describes the molecules in different states of matter(solid, liquids, or gases)?

• The molecules in a solid have potential energy because they are not in motion.

• The molecules in solids have potential energy, while liquids and gases have kinetic energy.

• The molecules in liquids have more kinetic energy than the molecules in gases.

• The molecules in solids, liquids, and gases have kinetic energy because they are in motion or vibrating.

Which of the following objects has the most kinetic energy?
