Investigate and report on legislation such as the Clean Water Act and its impact on the quality of Delaware water.
Earth’s dynamic systems are made up of the solid earth (geosphere), the oceans, lakes, rivers, glaciers and ice sheets (hydrosphere), the atmosphere, and organisms (biosphere). Interactions among these spheres have resulted in ongoing changes to the system. Some of these changes can be measured on a human time scale, but others occur so slowly, that they must be inferred from geological evidence.
Technology enables us to better understand Earth’s systems. It also allows us to analyze the impact of human activities on Earth’s systems and the impact of Earth’s systems on human activity.
