| 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. |
| 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. |
| 9-12 | ESS2.A: Earth materials and systems |
Feedback effects exist within and among Earth's systems. |
