FAQs on Drainage Class 9 Worksheet Geography Chapter 1

1. What is drainage?
Ans. Drainage refers to the process of removing excess water or liquid from an area, such as from the surface of the land or from a building, to prevent flooding or waterlogging.
2. Why is drainage important in agriculture?
Ans. Drainage is important in agriculture as it helps in removing excess water from the soil, preventing waterlogging and providing proper aeration to the roots of plants. It also helps in controlling soil erosion and improves the fertility of the soil.
3. What are the different types of drainage systems?
Ans. There are two main types of drainage systems: surface drainage and subsurface drainage. Surface drainage involves the removal of excess water from the surface of the land through channels, ditches, or drains. Subsurface drainage involves the installation of pipes or tiles below the ground to remove excess water from the soil.
4. How does poor drainage affect buildings?
Ans. Poor drainage can have various negative effects on buildings. It can lead to the accumulation of water around the foundation of the building, causing it to weaken and potentially collapse. It can also result in the growth of mold and mildew, which can cause health issues. Additionally, poor drainage can cause water seepage into basements or crawl spaces, leading to damage to the structure and belongings.
5. What are the common methods of improving drainage?
Ans. There are several common methods of improving drainage, including grading the land to create slopes that direct water away from the area, installing surface drains or channels to remove excess water, and using subsurface drainage systems such as French drains or perforated pipes. Additionally, proper maintenance of existing drainage systems and regular removal of debris can also help improve drainage.
