Share & grow the world's knowledge!
We want to connect the people who have knowledge to the people who need it, to bring together people with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
Relate various physiographic divisions you have studied in the earlier grades with various endogenic forces responsible for their origin.
• Fold mountains, such as the Himalayas, were formed by the collision of tectonic plates. • Plateaus were formed due to volcanic activity or the uplift of the Earth's crust. • Rift valleys developed where tectonic plates moved apart. • Volcanoes formed when magma rose through cracks in the Earth's cRead more
• Fold mountains, such as the Himalayas, were formed by the collision of tectonic plates.
• Plateaus were formed due to volcanic activity or the uplift of the Earth’s crust.
• Rift valleys developed where tectonic plates moved apart.
• Volcanoes formed when magma rose through cracks in the Earth’s crust.
• Earthquakes occur due to sudden movements along plate boundaries.

What are the sources of energy that are required to cause movements associated with the internal forces of the Earth?
The movements associated with the Earth's internal forces are mainly powered by heat energy from the Earth's interior. This heat comes from the Earth's formation and the radioactive decay of elements inside the Earth. It creates convection currents in the mantle, which move tectonic plates and leadRead more
The movements associated with the Earth’s internal forces are mainly powered by heat energy from the Earth’s interior. This heat comes from the Earth’s formation and the radioactive decay of elements inside the Earth. It creates convection currents in the mantle, which move tectonic plates and lead to earthquakes, volcanic eruptions, and mountain building.

Why should we study Social Science?
Social Science helps us understand the systems (roads, schools, markets, digital spaces) that shape our daily lives. It explains why differences in language, customs, and occupation exist and helps us recognise the underlying unity within diversity. It also prepares us to participate responsibly inRead more
Social Science helps us understand the systems (roads, schools, markets, digital spaces) that shape our daily lives. It explains why differences in language, customs, and occupation exist and helps us recognise the underlying unity within diversity. It also prepares us to participate responsibly in civic life, think critically about shared challenges like environment and employment, and connects the past, present, and future to help us make wiser choices.

History writing draws on archaeological and literary traditions such as travelogues, memoirs, correspondence, genealogical records, folklore and oral traditions, and revenue documents. Archaeological sources include monuments, architectural structures, excavated sites, artefacts, objects, and art such as sculptures and paintings, often analysed using scientific instruments and laboratory testing.

See lessUsing the example of a drought, explain why Social Science is studied through multiple disciplines.
A drought affects crops (environment), farmers' incomes (economy), government relief measures (politics), migration to cities (society), and traditional ways of coping with scarcity (culture). To understand such situations, we must examine society from different perspectives. This is why Social ScieRead more
A drought affects crops (environment), farmers’ incomes (economy), government relief measures (politics), migration to cities (society), and traditional ways of coping with scarcity (culture). To understand such situations, we must examine society from different perspectives. This is why Social Science is not a single subject but a group of related disciplines that together provide a comprehensive understanding of society.
