The most important justification for the framework’s increased emphasis on ESS is the rapidly increasing relevance of earth science to so many aspects of human society.It may seem as if natural hazards, such as earthquakes and hurricanes, have been more active in recent years, but this is primarily because the growing population of cities has heightened their impacts.Understanding the different processes that cause Earth to change over time (in a sense, how it “works”) therefore requires knowledge of the multiple systems’ interconnections and feedbacks.In addition, Earth is part of a broader system—the solar system—which is itself a small part of one of the many galaxies in the universe.And many of the conclusions drawn from this science, along with some of the evidence from which they are drawn, are accessible to today’s students. C: The History of Planet Earth Core Idea ESS2: Earth’s Systems ESS2. B: Plate Tectonics and Large-Scale System Interactions ESS2. The selection of much of the framework’s content was informed by these documents, thereby ensuring that the ESS core ideas we present are not only current and accurate but also relevant; they express content that the science research communities themselves recognize as being most important.Core Idea ESS1: Earth’s Place in the Universe ESS1. C: The Roles of Water in Earth’s Surface Processes ESS2. E: Biogeology Core Idea ESS3: Earth and Human Activity ESS3. The framework includes a broader range of ideas in ESS than previous efforts related to science education standards, largely because of pertinent recent developments in ESS and the increasing societal importance of Earth-related issues.

The history of the universe, and of the structures and objects within it, can be deciphered using observations of their present condition together with knowledge of physics and chemistry.
Similarly, the patterns of motion of the objects in the solar system can be described and predicted on the basis of observations and an understanding of gravity.
However, the underlying traditional discipline of geology, involving the identification, analysis, and mapping of rocks, remains a cornerstone of ESS.
Earth consists of a set of systems—atmosphere, hydrosphere, geosphere, and biosphere—that are intricately interconnected.
