| 6-8 | ESS2.A: Earth materials and systems |
Energy flows and matter cycles within and among Earth's systems, including the sun and Earth's interior as primary energy sources. Plate tectonics is one result of these processes. |
| 6-8 | ESS3.A: Natural resources |
Humans depend on Earth's land, ocean, atmosphere, and biosphere for different resources, many of which are limited or not renewable. Resources are distributed unevenly around the planet as a result of past geologic processes. |
| 9-12 | ESS2.A: Earth materials and systems |
Feedback effects exist within and among Earth's systems. |
