EES 102: Introduction to Earth Sciences (3)
Learning Objectives:
This is an undergraduate level course to introduce students to the basic concepts of Earth Science. The course gives an introduction to the dynamic planet Earth, explains the natural principles and processes that govern how its interior works and couples with the external system. In essence, this course provides a beginner's guide to planet Earth. Upon the completion of this course the student will have an understanding of the co-evolution of the Earth and life.
