Document Summary
Scientists collect data on natural phenomena such as tsunami, but it is often politicians (and indirectly, people who elect them) who determine what actions should be taken to protect the public. In addition, the sun and assorted features from space, collectively termed the exosphere interact with the earth system and are sometimes considered a 5th earth system component. Example: 2004 tsunami: involved 3 of the components: hydrosphere (ocean), geosphere (sea floor earthquake) and biosphere (people, plants, animals) - figure 1. 4, Key point: science is a process of discovery, a way of thinking about the world around us, and that increases our body of knowledge. Earth scientists combine their basic knowledge of facts and concepts with tehcnical skills to explore earth and solve its mysteries. The example of the hutchinson gas explosions (p8-p9) shows that scientific investigations are driven forward by the curiosity and presistence of scientists who systematically rule out potential solutions to arrive at an explanation.
