Disciplinary Core Ideas in Earth and Space Science

Earth and space sciences examine processes on Earth and compare them to processes elsewhere in the solar system and galaxy. The earth and space sciences often draw on physical and life sciences, and much of Earth and space science is interdisciplinary. Geology is used to understand the past and present of the earth and other celestial bodies. On Earth, scientists seek to understand the interconnected systems that drive the cycling of materials and energy and cause change over time. In Earth and space sciences, the framework emphasizes interconnections at many scales.

One Earth system, the hydrosphere, encompasses the ocean and freshwater systems on Earth. This system interacts with other large-scale Earth systems, including the atmosphere, the geosphere, and the biosphere. Water from the hydrosphere cycles through and shapes the other Earth systems, bringing with it matter and energy. The ocean is closely tied to weather and climate, including global climate change. The ocean and freshwater bodies also provide many natural resources and are especially vulnerable to human impact. For example, marine debris is waste that has accidentally or purposefully been released into the ocean. Marine debris can include fishing nets and gear, plastics bags, bottles, and other garbage that has made its way into the ocean. Marine debris can entangle organisms (Fig. 2.23), be mistakenly consumed by animals, or poison organisms with toxic chemicals.
