Impact of Deforestation on Water Movement
Deforestation significantly alters the natural processes of water infiltration into the ground. Here's how:
1. Reduced Vegetation Cover
- Trees and plants play a vital role in absorbing rainfall and facilitating water movement into the soil.
- When forests are cut down, there is less vegetation to capture rainwater, leading to increased surface runoff.
2. Soil Structure Disruption
- Tree roots help to create pathways in the soil, allowing water to penetrate more easily.
- Deforestation leads to soil compaction and degradation, which reduces the soil's ability to absorb water.
3. Increased Erosion
- Without trees, the soil becomes more susceptible to erosion by wind and water.
- Erosion removes the topsoil, which is rich in organic matter and crucial for retaining moisture.
4. Altered Hydrological Cycle
- Forests contribute to the hydrological cycle by releasing water vapor into the atmosphere through transpiration.
- Deforestation disrupts this cycle, leading to less atmospheric moisture and reduced rainfall.
5. Consequences of Reduced Infiltration Rate
- With reduced infiltration, more water runs off the surface rather than soaking into the ground.
- This can lead to flooding and decreased groundwater recharge, affecting water availability for plants, animals, and humans.
In conclusion, the correct answer is option 'C' - Reduced infiltration rate. Deforestation diminishes the natural mechanisms that facilitate water movement into the ground, resulting in less water being absorbed and more being lost to runoff.
