Understanding historical dating
The rapidly rising number of humans on the planet—doubling in number roughly every 40 years—combined with increased global industrialization, has also stressed limited planetary resources of water, arable land, plants and animals, minerals, and hydrocarbons.
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.
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.
These systems have differing sources of energy, and matter cycles within and among them in multiple ways and on various time scales.
Small changes in one part of one system can have large and sudden consequences in parts of other systems, or they can have no effect at all.arth and space sciences (ESS) investigate processes that operate on Earth and also address its place in the solar system and the galaxy.
