12 chapters covering Geography, History, Civics and Economics — NCERT Class 6
Globe vs Map: A globe is a 3-D model of the Earth that shows true shape, size and position of continents and oceans. A map is a 2-D flat representation. Maps can show the whole world or a small locality in great detail.
Three Components of a Map: (1) Distance — measured using a scale that relates map distance to actual ground distance. (2) Direction — shown using a compass rose; four cardinal directions (N, S, E, W) and four intermediate ones (NE, NW, SE, SW). (3) Symbols — conventional signs used to represent features like roads, rivers, railways, settlements.
Types of Maps: Physical maps (show natural features — mountains, rivers, plains), Political maps (show boundaries, states, capitals), Thematic maps (show specific data — rainfall, population, soil types).
Latitudes (Parallels): Imaginary horizontal circles running east-west. The Equator is 0°. Latitudes range from 0° to 90°N (North Pole) and 0° to 90°S (South Pole). Total: 181 lines (90N + 90S + Equator). Important lines: Tropic of Cancer (23.5°N), Tropic of Capricorn (23.5°S), Arctic Circle (66.5°N), Antarctic Circle (66.5°S).
Longitudes (Meridians): Imaginary vertical semicircles running from pole to pole. The Prime Meridian (0°) passes through Greenwich, England. Longitudes range from 0° to 180°E and 0° to 180°W. Total: 360 lines. All longitudes are equal in length.
Grid System: The network formed by intersecting latitudes and longitudes. Any place on Earth can be located by stating its latitude and longitude (e.g., Delhi: 28.6°N, 77.2°E).
Hemispheres: The Equator divides Earth into Northern and Southern hemispheres. The Prime Meridian divides Earth into Eastern and Western hemispheres.
Time Zones: Earth rotates 360° in 24 hours = 15° per hour. Each 15° of longitude = 1 hour time difference. India’s Standard Meridian is 82.5°E (IST = GMT + 5:30).

Water-Land Ratio: About 71% of Earth’s surface is water and 29% is land. That is why Earth is called the “Blue Planet.”
Seven Continents (by size, largest to smallest): Asia, Africa, North America, South America, Antarctica, Europe, Australia/Oceania.
Five Oceans (by size, largest to smallest): Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, Arctic Ocean.
Pangaea Theory: About 250 million years ago, all continents were joined as a single landmass called Pangaea (meaning “all lands”), surrounded by a single ocean called Panthalassa. Over millions of years, tectonic plate movements broke Pangaea apart into the continents we see today.
Asia: Largest continent. Home to the highest mountain (Mt Everest, 8,849 m), largest lake (Caspian Sea) and most populous countries (China, India).
Africa: Second largest. Has the longest river (Nile, ~6,650 km), largest desert (Sahara) and the most countries (54).
Antarctica: The coldest, driest, windiest and highest (by average elevation) continent. Covered in ice, no permanent human population.
Pacific Ocean: Largest and deepest ocean. Contains the Mariana Trench (deepest point on Earth at ~11,034 m). Covers more area than all the land on Earth combined.
| Term | Meaning |
|---|---|
| Continent | A large continuous mass of land |
| Ocean | A vast body of saltwater covering much of Earth’s surface |
| Pangaea | The supercontinent that existed ~250 million years ago |

| Isthmus | A narrow strip of land connecting two larger landmasses (e.g., Isthmus of Panama) |
| Strait | A narrow passage of water connecting two larger water bodies |
| Tectonic Plates | Large pieces of Earth’s crust that move slowly over time |
Mountains: Elevated landforms with steep slopes and narrow summits. Types: (1) Fold mountains (Himalayas, Alps — formed by tectonic collision), (2) Block mountains (Vindhyas — formed by faulting), (3) Volcanic mountains (Mt Kilimanjaro — formed by volcanic eruptions). Mountains influence climate by blocking winds and causing rainfall on the windward side.
Plateaus: Flat-topped elevated areas with steep sides. Also called “tablelands.” Rich in minerals (Deccan Plateau — iron, coal, manganese; African Plateau — gold, diamonds). Often called the “storehouses of minerals.”
Plains: Flat, low-lying areas, usually formed by river deposition. Most densely populated because of fertile soil, gentle slopes and easy transport. Examples: Indo-Gangetic Plain, Great Plains of North America.
Deserts: Extremely dry regions receiving less than 25 cm of rainfall annually. Hot deserts (Sahara, Thar) have extreme day-night temperature variation. Cold deserts (Ladakh, Gobi) are at high altitudes with freezing temperatures.
Valleys: Low-lying areas between hills or mountains, often carved by rivers. River valleys are very fertile (e.g., Kashmir Valley, Nile Valley).
Erosion and Deposition: Rivers erode the land in their upper course (V-shaped valleys, waterfalls) and deposit sediment in their lower course (deltas, floodplains). Wind erosion shapes desert landforms (sand dunes, mushroom rocks). Glaciers create U-shaped valleys and moraines.
| Term | Meaning |
|---|---|
| Landform | A natural feature of the Earth’s surface |
| Fold Mountain | Mountain formed by folding of Earth’s crust due to tectonic forces |

BCE & CE System: BCE = Before Common Era (counting backwards from year 1). CE = Common Era (counting forwards from year 1). There is no year 0. Example: 500 BCE came before 200 BCE; 200 CE came after 100 CE.
Primary Sources: First-hand evidence from the time period being studied. Types: (1) Inscriptions — writings engraved on stone, metal or clay (e.g., Ashoka’s rock edicts). (2) Coins (Numismatics) — reveal rulers, dates, trade routes, metals used. (3) Manuscripts — handwritten on palm leaves, birch bark or paper. (4) Monuments & Artefacts — buildings, tools, pottery, sculptures found at archaeological sites.
Secondary Sources: Works created later, based on primary sources. Books, articles, documentaries written by historians interpreting past events.
Archaeology: The scientific study of human history through excavation and analysis of physical remains (pottery, bones, tools, ruins). Archaeologists dig in layers — deeper layers are older.
Carbon Dating (C-14): A scientific method to determine the age of organic materials (wood, bone, cloth) up to ~50,000 years old. Based on the decay rate of radioactive Carbon-14.
Oral Traditions: Stories, songs, customs and knowledge passed down through generations by word of mouth, before writing systems existed.

Town Planning (Grid Pattern): Cities were planned on a grid pattern with streets crossing at right angles. Two parts: Citadel (upper town — public buildings, granary) and Lower Town (residential areas). Houses were made of standardised baked bricks (ratio 1:2:4).
Advanced Drainage System: Every house had drains connected to street drains, which led to covered underground sewage channels. One of the most advanced drainage systems of the ancient world.
Great Bath (Mohenjo-daro): A large, watertight bathing pool (~12m x 7m x 2.4m deep) made of baked bricks sealed with bitumen. Likely used for ritual bathing.
Seals: Over 2,000 seals found, mostly made of steatite. The most famous is the Unicorn seal. Seals had animal figures and an undeciphered script. Used for trade identification and as amulets.

Roles of Family Members: Every member contributes — earning income, household work, childcare, elderly care. The chapter emphasises that these roles should not be fixed by gender. Both men and women should share all responsibilities.
Gender Stereotypes in Families: Traditional stereotypes assign cooking/cleaning to women and earning/outdoor work to men. These stereotypes are harmful and limit both men’s and women’s potential. All work (household and professional) deserves equal respect.
Community: A group of people living in the same area, sharing spaces, resources and responsibilities. Strong communities are built on cooperation, mutual respect and shared decision-making.
Neighbourhood: The immediate area around one’s home. Good neighbourhoods have cooperation (helping during emergencies), shared facilities (parks, markets, schools) and conflict resolution mechanisms.

(3) Nagar Panchayat — for areas transitioning from rural to urban.
Ward System: Cities are divided into wards. Each ward elects a councillor (also called corporator). All councillors together form the municipal council/corporation. The Mayor is elected from among the councillors (in most states).
Functions: Water supply, sewage and drainage, solid waste management, road construction and maintenance, streetlighting, fire services, public health, birth and death registration, building permissions, maintenance of parks and public spaces, urban planning.
74th Constitutional Amendment (1992): Gave constitutional status to urban local bodies. Key provisions: regular elections every 5 years, reservation for women (1/3), SC/ST reservation, State Finance Commission for fund allocation, constitution of ward committees.
Revenue Sources: Property tax (the main source), water and sewage charges, entertainment tax, advertisement fees, government grants, development charges on new constructions.

Three Sectors of Work: (1) Primary Sector — activities that involve natural resources directly: agriculture, fishing, mining, forestry, animal husbandry. Also called the “agricultural sector.” (2) Secondary Sector — activities that transform raw materials into finished goods: manufacturing, construction, factory work. Also called the “industrial sector.” (3) Tertiary Sector — activities that provide services: banking, teaching, transport, healthcare, IT, tourism. Also called the “service sector.”
Dignity of Labour: Every type of honest work deserves equal respect, whether manual, intellectual or creative. A farmer’s work is as valuable as a doctor’s or a teacher’s. No work is “big” or “small” — all work contributes to society and the economy.
Gender and Work: Women often do unpaid household work (cooking, cleaning, childcare) in addition to paid employment. This “double burden” is often invisible. The chapter emphasises that work should not be divided by gender — men and women should have equal opportunities in all fields.
Child Labour: Employing children (under 14) in work that deprives them of education, health and childhood. It is illegal under Indian law (Child Labour Act, 1986; amended 2016). Causes: poverty, lack of schools, family debt. Effects: loss of education, health hazards, exploitation.
Needs vs Wants: Needs are essentials for survival (food, clothing, shelter, education, healthcare). Wants are extras that improve comfort but are not essential (gadgets, luxury items). Understanding this distinction helps in making wise economic choices.
Interdependence of Sectors: All three sectors depend on each other. A farmer (primary) sells wheat to a flour mill (secondary), which supplies bakeries served by delivery people (tertiary). No sector can function in isolation.
| Term | Meaning |
|---|---|
| Primary Sector | Sector dealing with natural resources (agriculture, mining, fishing) |
| Secondary Sector | Sector that transforms raw materials into finished goods (manufacturing) |
| Tertiary Sector | Sector providing services (banking, transport, teaching, IT) |
| Dignity of Labour | The belief that all honest work is equally respectable |
| Child Labour | Employment of children in work that harms their development |
| Livelihood | The means by which a person earns their living |
| Self-employed | A person who works for themselves rather than for an employer |
| Interdependence | Mutual dependence between sectors, people or economies |
