Water Resources

7. Flood that occurs when heavy rainfall creates a flood event independent of an overflowing stream
9. Second layer of the ocean, where the temperature of the water decreases rapidly with depth
11. When this occurs, river flow increases, and the volume of the world ocean increases, resulting to a rise in sea level and reduced land area
13. Evaporation of water from the leaves and stems of plants
16. Land areas where water covers the surface for significant periods
17. Narrow, elongated landform separating individual streams within a basin
19. Process whereby rain that falls into land surface penetrates the soil
20. Partly enclosed coastal body of water where freshwater from stream meets the saltwater from the sea

1. Streams that are fed by groundwater
2. Impermeable rocks where water is trapped and held down by pressure between them.
3. Process whereby too much soil and sediments are delivered to streams
4. It is only 2. 5% of Earth’s total water
5. Smaller streams
6. Reduction of the mineral content by taking salt out of the seawater to produce freshwater
8. Part of Earth’s subsystem containing the oceans, lakes, streams, underground water, and snow and ice
10. Zone or land area where water enters the ground and replenish the groundwater.
12. Ability of the rock or sediments to allow water to pass through it
14. This is a zone in which the spaces between the particles are filled mainly with air.
15. Saltiness of saltwater
18. Soil, rock or sediment that is frozen for more than two consecutive years
