Effect of Cutting Trees on Hillsides
Deforestation on hillsides can have significant impacts, especially regarding rainfall and water management.
Rainfall and Water Cycle Disruption
- Trees play a vital role in the water cycle by absorbing rainfall and releasing moisture back into the atmosphere through a process called transpiration.
- When trees are cut down, this process is disrupted, leading to decreased moisture levels in the air.
Increased Runoff and Erosion
- Without trees, the soil becomes less stable and more susceptible to erosion.
- Rainfall that would typically be absorbed by tree roots instead becomes surface runoff, leading to rapid water flow down the hillsides.
Flooding in Low-Lying Areas
- The increased runoff can overwhelm rivers and streams, especially during heavy rainfall.
- This can cause flooding in low-lying areas downstream, as the water has nowhere to go and accumulates rapidly.
Conclusion
- Cutting trees on hillsides can significantly alter rainfall patterns and increase the risk of flooding.
- It is essential to maintain forest cover to ensure a balanced hydrological cycle and prevent environmental disasters like flooding.
In summary, the correct answer to the impact of cutting trees on hillsides in terms of rainfall is option 'C'. The loss of trees increases runoff, leading to flooding in low-lying areas.
What is the effect of cutting trees on hillsides in terms of rainfall?...
Cutting trees on hillsides can lead to rainwater flowing down bare mountains, causing flooding in low-lying areas. Trees help in preserving water and preventing floods.
