Class 6 Social Science - ICSE-GEOGRAPHY
Major Landforms
The chapter 'Major Landforms' introduces Class 6 ICSE Geography students to the diverse relief features of the Earth's surface. It covers the formation, types, and importance of mountains, plateaus, and plains, which are the three primary landforms. Students will learn how internal and external geological forces continuously shape our planet. Understanding these landforms is crucial for board exams as it builds the foundational knowledge of physical geography, map reading, and human-environment interactions. Questions from this chapter frequently test the ability to differentiate between landform types and explain their economic significance.

Mountains
A mountain is any natural elevation of the Earth's surface rising abruptly from the surrounding area, categorized into fold, block, and volcanic mountains.
Plateaus
Plateaus are elevated, flat-topped tablelands that stand significantly above the surrounding area, often rich in mineral deposits.
Plains
Plains are broad, nearly flat stretches of land that are usually very fertile and heavily populated due to ease of agriculture and transport.
Fold Mountains
Mountains formed when two tectonic plates collide and compress sedimentary rocks upwards into folds, such as the Himalayas and the Alps.
Endogenic and Exogenic Forces
Endogenic forces are internal forces that cause upliftment and sinking of the Earth's surface, while exogenic forces are external forces like erosion and deposition that wear down and rebuild landforms.

Board Exam Info
In ICSE Class 6 Geography, this chapter typically carries 8 to 12 marks. Common question types include direct definitions, differentiating between mountains and plateaus, identifying examples of specific landforms on a world map, and short-answer questions explaining the economic importance of plains.
Frequently Asked Questions
What is the difference between a mountain and a plateau?
A mountain has a peaked or narrow summit and steep slopes, whereas a plateau is a flat-topped, elevated tableland that is broad at the top.
Why are plains densely populated?
Plains are heavily populated because they have flat land suitable for building houses and transport networks, and possess fertile soil brought down by rivers, which is ideal for agriculture.
How are block mountains formed?
Block mountains are formed when great forces acting in the Earth's crust cause cracks or faults. The land between the cracks drops down or the land on either side rises, creating elevated blocks called horsts.
