he table below shows a diagram of part of a watershed.
In the diagram above, region B is the _______ .
a
discharge zone
b
recharge zone
c
saturated zone
d
unsaturated zone
Recharge zone
In the diagram above, region B is the recharge zone.
To determine the correct answer, we need to understand the definitions of the given terms: discharge zone, recharge zone, saturated zone, and unsaturated zone.
- Discharge zone refers to an area where water flows out or is released from an aquifer, such as a river or a spring.
- Recharge zone refers to an area where water replenishes an aquifer, usually through percolation or infiltration of surface water.
- Saturated zone refers to an area of an aquifer where the spaces between the soil or rock particles are completely filled with water.
- Unsaturated zone refers to an area above the water table where the soil or rock contains some water, but also has space filled with air.
Now, let's analyze the diagram to determine which term describes region B.
Based on the diagram, it does not show water flowing out (discharging) or being released from the aquifer in region B. Additionally, it does not show water replenishing (recharging) the aquifer through percolation or infiltration.
However, the diagram does show region B as an area where the spaces between the soil or rock particles are completely filled with water. This corresponds to the definition of the saturated zone.
Therefore, the correct answer is c) saturated zone.
