A comparison of the science of Earth as compared with the other planets in our solar system.

a. Much is known about planet Earth, as it is our home planet. It is therefore an ideal planet for comparative planetology. Briefly describe the properties of our planet and explain them. Include the qualities of the earth's interior, and how we learn about it, as well as a description of properties that shape and change the earth's surface (i.e. impact cratering, volcanism, tectonics, erosion).

b. Then, examine each planet in our solar system. How does it compare to Earth? What are its unique characteristics? Why do these features exist on that planet, as opposed to Earth?

you can use popular astronomy magazines and reputable Web sites. Jet Propulsion Laboratory (JPL) and National Aeronautics and Space Administration (NASA) Web sites (http://www.jpl.nasa.gov/ and http://www.nasa.gov/), will assist you in finding the latest information on planets.
