Water Resources

2. Land areas where water covers the surface for significant periods
7. Soil, rock or sediment that is frozen for more than two consecutive years
9. It is only 2. 5% of Earth’s total water
10. 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
14. Impermeable rocks where water is trapped and held down by pressure between them.
15. This is a zone in which the spaces between the particles are filled mainly with air.
17. Smaller streams
18. Flood that occurs when heavy rainfall creates a flood event independent of an overflowing stream
19. Saltiness of saltwater
20. Partly enclosed coastal body of water where freshwater from stream meets the saltwater from the sea

1. Part of Earth’s subsystem containing the oceans, lakes, streams, underground water, and snow and ice
3. Process whereby too much soil and sediments are delivered to streams
4. Narrow, elongated landform separating individual streams within a basin
5. Process whereby rain that falls into land surface penetrates the soil
6. Zone or land area where water enters the ground and replenish the groundwater.
8. Reduction of the mineral content by taking salt out of the seawater to produce freshwater
12. Ability of the rock or sediments to allow water to pass through it
16. Streams that are fed by groundwater
