| 3-5 | ESS2.A: Earth materials and systems |
Four major Earth systems interact. Rainfall helps to shape the land and affects the types of living things found in a region. Water, ice, wind, organisms, and gravity break rocks, soils, and sediments into smaller pieces and move them around. |
| 3-5 | ESS3.C: Human impacts on Earth systems |
Societal activities have had major effects on the land, ocean, atmosphere, and even outer space. Societal activities can also help protect Earth's resources and environments. |
| 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.C: Human impacts on Earth systems |
Human activities have altered the biosphere, sometimes damaging it, although changes to environments can have different impacts for different living things. Activities and technologies can be engineered to reduce people's impacts on Earth. |
