| Grade | Discipline | Core Idea |
|---|---|---|
| 3-5 | ESS2.C: The roles of water in Earth's surface processes | Most of the Earth's water is in the ocean and much of the Earth's fresh water is in glaciers or underground. |
| 6-8 | ESS2.C: The roles of water in Earth's surface processes | Water cycles among land, ocean, and atmosphere, and is propelled by sunlight and gravity. Density variations of sea water drive interconnected ocean currents. Water movement causes weathering and erosion, changing landscape features. |
