Question

A large portion of the water that falls on the Earth is absorbed by plants and used in photosynthesis. The plants secure the soil with their spreading roots, which of the following practices, would contribute the most to periodic flooding in an area

1. Building terraces on farmland with sloping fields.
2. Constructing dams to generate electricity.
3. Irrigating crops with well water or water from nearby, lakes or streams.
4. Planting vegetables crops along waterways
5. removing the natural plant cover and leaving the land barren

Answer 1

5. Removing the natural plant cover and leaving the land barren

This practice would contribute the most to periodic flooding in an area because without the plants to absorb the water, there is nothing to prevent excessive water from running off the land and causing flooding. The natural plant cover helps to slow down the flow of water, allowing it to seep into the soil and be absorbed by plants, reducing the risk of flooding.
