Chapter 1: Introduction of Earth Science 1.  Why Do We Study Earth Science?  Earth scientists are “scientific detectives who try to reveal the past and the future of the Earth”  Earth scientists can use information about the rocks in a certain area to get an idea about what it was like there in the past  Earth scientists can use the information about the past to help prepare for possible hazards in the future  Earth scientists can also find materials that can be used as resources 2.  How Do We Study Earth Science?  The scientific method is a set of steps that scientists use to develop explanations for how things work or came to be  The framework of the scientific method is universal:   Observe and recognize a phenomenon   Develop a hypothesis (tentative explanation)  Conduct experiments to test the hypothesis   Interpret the data, and possibly develop a new hypothesis  Once   extensive   testing   by   multiple   investigators   has   exhausted reasonable doubt, it becomes a theory
