FAQs on Mindmap: Major Landforms of the Earth - Class 6 to 12 NCERT Mindmaps for UPSC Preparation

1. What are the major landforms on Earth?
Ans. The major landforms on Earth include mountains, plateaus, plains, hills, and valleys. These landforms are the result of various geological processes and have distinct characteristics.
2. How are mountains formed?
Ans. Mountains are formed through tectonic processes, such as the collision of tectonic plates or volcanic activity. When two plates collide, they can push up the Earth's crust, resulting in the formation of mountains. Volcanic activity can also lead to the formation of mountains when molten rock erupts and builds up over time.
3. What are plateaus and how are they formed?
Ans. Plateaus are flat elevated landforms with steep sides. They are formed through various geological processes, including volcanic activity and erosion. Volcanic plateaus are formed when lava flows spread out over a large area and solidify, creating a flat surface. Erosional plateaus are formed when external forces, such as wind, water, or glaciers, erode the surrounding land, leaving a flat-topped plateau behind.
4. What are plains and where are they commonly found?
Ans. Plains are large, flat areas of land characterized by low relief. They are commonly found in regions with low elevation, such as coastal areas and river valleys. Plains are often formed through the deposition of sediments by rivers, which create a level surface over time. They are important for agriculture and human settlements due to their fertile soil.
5. How are valleys formed?
Ans. Valleys are formed through various geological processes, including erosion by rivers, glaciers, or tectonic activity. River valleys are commonly formed when a river cuts through the land over a long period, gradually eroding the surrounding rocks and creating a V-shaped valley. Glacial valleys, on the other hand, are formed when glaciers carve through the land, creating U-shaped valleys. Tectonic activity, such as the shifting of Earth's crust, can also create valleys.
