Planet Earth

Online Course

University of Illinois

Price: Free
Website: http://www.coursera.org/course/earth
Description: This online course teaches you how the elements comprising the Earth formed in the guts of stars and supernovae, how Earth and its Solar System neighbors formed from a vast cloud of gas and dust over 4.5 billion years ago. And how the atmosphere, oceans, and rocks of our planet form and change.

You will also learn the fascinating interactions and exchanges that take place among land, sea, air, and life, and how these interactions they result in the great variety of landscapes—from deserts to glaciers—that make our planet unique, and influence climate change in the past and, potentially the future. Finally, you will delve into the processes that produce the energy and mineral resources that modern society depends on, to help understand the context of the environment and sustainability challenges that we will face in the future.
