FAQs on What are Landforms Video Lecture - Social Studies for Class 5

1. What are landforms?
Ans. Landforms are natural features of the Earth's surface. They include mountains, hills, valleys, plateaus, plains, and deserts. Each landform has its unique shape and characteristics, and they are formed through various natural processes like erosion, weathering, and tectonic activities.
2. How are mountains formed?
Ans. Mountains are formed mainly through tectonic activities. When tectonic plates collide, they push the Earth's crust upwards, creating mountains. This process can take millions of years. Other ways mountains can form include volcanic eruptions and the folding of the Earth’s crust.
3. What is the difference between a plateau and a plain?
Ans. A plateau is a flat area that is raised significantly above the surrounding land, often with steep sides. In contrast, a plain is a flat, low-lying area with little elevation. Plateaus are usually formed by volcanic activity or the uplift of land, while plains are often formed by sediment deposition from rivers.
4. What are the characteristics of valleys?
Ans. Valleys are low-lying areas between hills or mountains. They often have a river or stream running through them. Valleys can be V-shaped, formed by the erosion of rivers, or U-shaped, created by glacial activity. They are typically fertile and suitable for agriculture due to the rich soil found there.
5. Why are deserts important in our ecosystem?
Ans. Deserts play a crucial role in the ecosystem by supporting unique plants and animals adapted to extreme conditions. They help regulate temperature and climate, store carbon, and protect biodiversity. Deserts also play a role in the water cycle, as they can influence rainfall patterns in surrounding areas.
