FAQs on Major Landforms of the Earth Video Lecture - Geography Class 6 ICSE

1. What are the major landforms of the Earth?
Ans. The major landforms of the Earth include mountains, hills, plateaus, plains, and valleys. Mountains are elevated landforms that rise prominently above their surroundings. Hills are smaller than mountains and have a rounded shape. Plateaus are flat elevated areas, while plains are vast, flat stretches of land. Valleys are low areas between hills or mountains, often with a river running through them.
2. How are mountains formed?
Ans. Mountains are formed through various geological processes, primarily tectonic forces. When tectonic plates collide, they can push the Earth's crust upwards, creating mountain ranges. This process is known as orogeny. Additionally, volcanic activity can also create mountains when magma erupts from the Earth's interior.
3. What is the difference between a plateau and a plain?
Ans. The main difference between a plateau and a plain is their elevation. A plateau is a flat, elevated area that rises sharply above the surrounding land, while a plain is a flat or gently rolling area of land at a low elevation. Plateaus can be formed by volcanic activity or the uplift of the Earth's crust, whereas plains are typically formed by the deposition of sediments from rivers.
4. What are the characteristics of valleys?
Ans. Valleys are low-lying areas between hills or mountains, often formed by erosion caused by rivers or glaciers. They typically have a V-shape, created by river erosion, or a U-shape, formed by glacial activity. Valleys can be fertile and support agriculture due to the presence of river water and nutrient-rich soil.
5. Why are landforms important for human activities?
Ans. Landforms are crucial for human activities as they influence climate, agriculture, transportation, and settlement patterns. For example, plains are ideal for farming due to flat land, while mountains can provide resources like minerals and timber. Additionally, rivers in valleys can serve as transportation routes and sources of water, making landforms essential for economic development and habitation.
