FAQs on Coastal Plains and Islands (CBSE NCERT Social Science) Video Lecture - Class 7

1. What are the coastal plains and islands?
Ans. Coastal plains are flat areas of land located alongside the coastlines, while islands are land masses surrounded by water on all sides. Coastal plains are formed by the accumulation of sediments brought by rivers, ocean currents, and wind. Islands, on the other hand, are formed by various geological processes such as volcanic eruptions or tectonic movements.
2. How are coastal plains different from other types of plains?
Ans. Coastal plains differ from other types of plains in terms of their location and formation. Coastal plains are found along the coastlines, while other types of plains can be found inland. These plains are formed by the deposition of sediments brought by rivers and ocean currents, whereas other plains may be formed by different geological processes like erosion, glaciation, or volcanic activity.
3. What are some notable features of coastal plains and islands?
Ans. Coastal plains and islands have several distinct features. Coastal plains often have sandy beaches, dunes, marshes, and estuaries. They are also known for their fertile soil, which is suitable for agriculture. Islands, on the other hand, may have unique ecosystems and diverse flora and fauna due to their isolation. They can also have stunning natural landscapes, such as cliffs, caves, and coral reefs.
4. How do coastal plains and islands impact human settlements?
Ans. Coastal plains and islands have a significant impact on human settlements. Their proximity to the coast provides opportunities for fishing, trade, and tourism. Coastal plains often have ports and harbors, facilitating transportation and economic activities. Islands, on the other hand, may face challenges such as limited resources, isolation, and vulnerability to natural disasters. However, they can also attract tourists, supporting local economies.
5. How are coastal plains and islands important for biodiversity?
Ans. Coastal plains and islands are crucial for biodiversity. They provide diverse habitats for a wide range of plant and animal species. Coastal plains, with their estuaries and wetlands, support various migratory birds, marine animals, and mangrove forests. Islands, especially those with unique ecosystems, are home to endemic species found nowhere else. These areas are essential for the conservation of biodiversity and contribute to the overall ecological balance.
