Earth
We begin our study of the planets with our own planet, Earth.
Although we are still learning more about our planet all the time,
we know much more about it than we do any other. We will learn about
Earth's overall structure, including its interior, surface, and atmosphere.
We will gain understanding abut processes like plate tectonics and
the greenhouse effect. We will study the origin and effects due to the
magnetosphere, and finish by examining the gravitational coupling between
the earth and its moon, evidenced in the oceanic tides.
