| aquifer | any layer of rock or sediment that can hold water, below the saturated zone |
| well | a hole sunk into the ground to reach a supply of water |
| desalination | process to remove salt from ocean water to make fresh water |
| groundwater | in a watershed, water that seeps through the ground and is stored below the Earth's surface |
| hydrosphere | system that contains all the liquid and frozen water on Earth's surface, as well as the groundwater below the surface and water vapor in the atmosphere |
| surface water | natural water that is at or near the surface in a watershed.; drainage water |
| runoff | water that flows over the ground when it rains or when snow melts; does not soak into the soil but instead moves across the surface; can carry dirt, chemicals, and trash |

| fertilizer | chemical or natural substance added to soil or land to increase its fertility; can be a source of water pollution |
| ocean system | all the parts of the ocean that work together to support life and the environment; includes the water, currents, marine life, and the ocean floor |
| percolate/leach | to slowly move or filter through a substance; when rainwater soaks into the ground, it percolates or leaches through the soil and eventually reaches underground water sources |
| pollution | when harmful substances, like chemicals, trash, or smoke, are added to the air, water, or land |
| coral bleaching | happens when coral reefs lose their color and turn white; happens when the water gets too warm or when there’s too much pollution |
| subsidence | sunken land surface due to underlying compression of earth material as a result of excessive removal of groundwater |
| permeable | penetrable; porous; allowing liquids or gas to pass through |
| recreation | something done for fun, a hobby or game |
| Marine Protected Areas (MPAs) | areas designated and effectively managed to protect marine ecosystems, processes, habitats, and species; can contribute to the restoration and replenishment of resources for social, economic, and cultural enrichment |
