FAQs on Tundra region Video Lecture - UPSC
| 1. What is the tundra region? |  |
Ans. The tundra region refers to vast, treeless areas found in the Arctic and subarctic regions, characterized by extremely cold temperatures, short growing seasons, and permafrost. It is mainly composed of mosses, lichens, and low-lying shrubs.
| 2. What are the key features of the tundra region? | |
Ans. The key features of the tundra region include low temperatures, a short growing season, permafrost (permanently frozen ground), limited vegetation, and a fragile ecosystem. It experiences long, cold winters and short, cool summers.
| 3. How does the tundra region support life? | |
Ans. Despite its harsh conditions, the tundra region supports a variety of life forms. Animals such as polar bears, Arctic foxes, reindeer, and migratory birds are adapted to survive in this environment. The region's vegetation, including mosses, lichens, and dwarf shrubs, provides food and shelter for these species.
| 4. Why is the tundra region important for the global climate? | |
Ans. The tundra region plays a crucial role in the global climate system. Its permafrost stores large amounts of carbon, which, if released, can contribute to the greenhouse effect and climate change. Additionally, the tundra acts as a carbon sink, absorbing carbon dioxide from the atmosphere and helping to mitigate the impacts of global warming.
| 5. What are the environmental challenges faced by the tundra region? | |
Ans. The tundra region is facing several environmental challenges. Climate change is causing the permafrost to thaw, leading to habitat loss for tundra species and releasing greenhouse gases. Human activities, such as oil and gas exploration, mining, and pollution, also pose threats to this fragile ecosystem. Conservation efforts are crucial to protect the tundra region and its unique biodiversity.
