**Q1: A watershed experiences increased urbanization, resulting in higher peak runoff and reduced
groundwater recharge. Which hydrological change best explains this outcome?**
A) Increased infiltration due to vegetation growth
B) Decreased surface imperviousness
C) Increased impervious surfaces reducing infiltration
D) Increased evapotranspiration from soil moisture
**Correct Answer: C**
**Rationale:** Urbanization increases impervious surfaces such as roads and buildings, preventing
water infiltration and increasing surface runoff. This leads to higher peak discharge and reduced
,groundwater recharge. The other options incorrectly assume increased infiltration or evapotranspiration
processes that are typically reduced in urban environments.
---
**Q2: Which component of the hydrological cycle directly transfers water from vegetation back into the
atmosphere?**
A) Condensation
B) Evapotranspiration
C) Infiltration
D) Percolation
**Correct Answer: B**
**Rationale:** Evapotranspiration combines evaporation and plant transpiration, returning water from
vegetation and soil to the atmosphere. The other options represent subsurface or phase-change
processes not involving vegetation release.
---
**Q3: A river system shows increased sediment load after deforestation. What is the primary cause?**
A) Reduced precipitation intensity
B) Increased soil stability
C) Loss of root structures binding soil
D) Increased groundwater recharge
, **Correct Answer: C**
**Rationale:** Vegetation roots stabilize soil. Deforestation removes this structure, increasing erosion
and sediment transport into rivers.
---
**Q4: Which factor most directly affects groundwater recharge rates?**
A) Atmospheric pressure only
B) Soil permeability
C) Wind speed
D) Solar radiation intensity
**Correct Answer: B**
**Rationale:** Permeable soils allow water to infiltrate and recharge aquifers. Atmospheric and climatic
factors are indirect compared to subsurface properties.
---
**Q5: A catchment area experiences flash flooding. Which condition most likely contributes?**
A) High infiltration capacity soils
B) Steep slopes and low vegetation cover
