One of the unique features of the Earth is its crust. None of the other terrestrial planets seem to have a crust similar that of the Earth, and the reason for this is related to plate tectonics, which in turn is related to the way the mantle cools and how it has evolved. In that reason, knowing the evolution of the crust and mantle, and studying how this dynamic system has evolved as the Earth has cooled over the last 4.6Ga is important. To understand the origin and evolution of the mantle and crust including physical and chemical properties of it, I will read the chapter two (The Crust) and eight (Crustal and Mantle Evolution) from a book “Earth as an Evolving Planetary System” by Kent C. Condie. There are no major problems and challenges identified in the process since this project only needs reading.
