Across
- 4. Development: the process of building urban areas to accommodate growing populations.
- 7. the clearing or thinning of trees by humans.
- 8. movement of water through the surface of land. Percolation: movement of water through the soil itself.
- 9. pollution: the contamination of water bodies like lakes, oceans, rivers, and aquifers.
- 11. (water below the surface) the precipitation that seeps into the deeper layers of soil and is stored in spaces between or within rocks. This water will slowly flow back into the soil, streams, rivers, and oceans.
Down
- 1. body of rock and/or sediment that holds groundwater.
- 2. Fuels: the burning of coal, oil, and natural gas to produce energy.
- 3. table: the upper surface of underground water (groundwater)
- 5. the precipitation (water) that falls on the land and flows into streams, rivers, and lakes. When too much rain falls onto the ground, part of it "runsoff" downhill due to gravity.
- 6. usage: the use of water by various users like homes, agriculture, industries, and environmental needs.
- 10. the process that carries weathered material to new locations.
