Objectives On the completion of this subject students will be able to discuss and/or describe the birth and evolution of the universe and solar system; the earth's structure and chemistry; geophysical techniques used in deciphering the earth's structure and exploring for natural resources; geologic time and its importance in the evolution of the earth; the evolution of the earth's crust, in particular plate tectonics; and identify some common minerals and igneous and sedimentary rocks; the formation of igneous, sedimentary and metamorphic rocks; life in the early part of earth's history; similarities and differences in the atmospheres of earth and other terrestrial planets in the solar system.
Synopsis This subject introduces students to many of the aspects of earth sciences. In the beginning, we present theories on the birth and evolution of the universe, solar system and earth. This is followed by lectures on planetary geology, specifically the stucture and chemistry of the earth and other planets. The evolution of the earth, in particular its crust, is next, where we present the concepts of geologic time and plate tectonics. This provides a framework for examining the evolution of the crust and surface of the earth as well as those of other planets. We describe minerals, crystals, rocks and the processes that formed them. Finally, we talk about the birth and evolution of life on earth, the development of atmospheres on earth and other terrestrial planets and some of the present atmospheric problems we face in our environment.
