Across
  1. 6. The artificial application of water to land to assist in the growth of crops or vegetation.
  2. 8. Water that is found on the Earth's surface, such as in rivers, lakes, and reservoirs.
  3. 12. A large natural or artificial lake used for storing water for various purposes, such as irrigation, water supply, or hydroelectric power generation.
  4. 15. A microorganism, such as bacteria, viruses, or fungi, that causes disease.
  5. 17. Water located beneath the Earth's surface, usually in aquifers, that supplies wells and springs.
  6. 18. The degradation of water quality caused by a significant increase in water temperature, often from industrial processes or power plants.
  7. 21. The process by which water bodies become overly enriched with nutrients (often from agricultural runoff), leading to excessive plant growth and oxygen depletion.
Down
  1. 1. Pollution that comes from multiple, diffuse sources, such as runoff from agricultural fields, urban areas, or forests.
  2. 2. Pollution that comes from a single, identifiable source, such as a pipe or a factory discharge.
  3. 3. A layer of rock or sediment that holds water, often serving as a source of groundwater.
  4. 4. Water that has been used for domestic, industrial, or commercial purposes and is typically contaminated, requiring treatment before it can be returned to the environment.
  5. 5. The process by which the concentration of toxic substances increases as they move up the food chain, affecting predators at higher trophic levels.
  6. 7. The contamination of water bodies (such as rivers, lakes, and oceans) with harmful substances, making the water unsafe or harmful to living organisms.
  7. 9. System A network of rivers and streams that drain an area of land.
  8. 10. The ability of a material (such as rock or soil) to allow water to pass through it.
  9. 11. Water that is safe for drinking.
  10. 13. The area of land where all the water that falls or flows through it drains into a common outlet, such as a river or ocean.
  11. 14. A structure built across a river or stream to control the flow of water, often to store water or prevent flooding.
  12. 16. The process of removing salt and other minerals from seawater to make it suitable for drinking and irrigation.
  13. 19. An area where water infiltrates the ground and replenishes an aquifer.
  14. 20. The measure of empty spaces (pores) in a material, such as rock or soil, which determines how much water it can hold.
