landscape and Water

2. Water that is stored underground in the cracks and spaces of soil, sand, and rock.
4. A state that occurs when an aquifer's water supply is reduced or emptied because it is used faster than it is replaced.
7. The upper layer of soil and rock where the pore spaces are partially filled with air and partially with water.
8. An underground layer of highly permeable rock or sediment that contains usable amounts of groundwater.
10. The upper boundary line separating the zone of aeration from the zone of saturation.
12. The general physical features of the Earth's surface in a specific region.
13. A landscape feature with high elevation and high relief, often with distorted or folded rock structures.
14. A landscape feature with low elevation and low relief, usually consisting of flat rock layers.
15. The percentage of empty space (pores) within a rock or soil material, which determines how much water it can hold.

1. The process of surface water naturally infiltrating down into the ground to replenish an aquifer.
3. The process of surface water soaking into the ground to become groundwater.
5. Precipitation that flows over the Earth's surface instead of sinking into the ground.
6. The layer beneath the water table where all pore spaces are completely filled (saturated) with water.
9. A landscape feature with high elevation and low relief, typically consisting of flat, horizontal sedimentary rock layers.
11. The ability of rock or soil to allow water to flow freely through its interconnected pore spaces.
