And How It Got This Way.
Planet Earth is a very complex system which in many ways is like the body.
It is not static, but is dynamic and evolving with time. In this course we will learn how observations on the surface and the interior of the Earth have been used to construct a theory of the Earth. From observations on the present state of the Earth, we can backtrack and construct much about the history of the Earth over the past 4.6 billion years. Our current view of the Earth differs greatly from theories of only a few decades ago, and some history of Earth science will be discussed. We will also learn what the Earth's interior is like, even though we are able to barely pierce the shallowest levels with the deepest drillholes.
