Transfer of potential energy to kinetic can shape the earth's surface.
Examples include impact craters, landslides, earthquakes, the effects
of wave action, and the energy of removal and accumulation. In Unit
2 you explored various forms of energy and examined how energy transferred
around our dynamic planet.
Potential and Kinetic Energy review
Kinetic energy - energy associated with motion.
Potential energy - stored energy ready to be released and converted
to other forms of
energy, such
as kinetic.
Pushing a ball uphill gives it potential energy. Then it falls
down due to gravity, illustrating
kinetic energy.
A. Craters
Since falling objects are the classic example of potential eneregy
to kinetic energy, we can use falling objects to show how kinetic energy
can effect the earth's surface. We will begin our exploration with impact
craters.
B. Landslides
Landslides are good examples of mass movement caused by the conversion
of potential energy to kinetic energy.
C. Earthquakes
An earthquake is a movement of the ground caused by the sudden release
of potential energy to kinetic energy.
D. Wave Action
The energy from wave activity is important in the erosion and deposition
of materials.
