Locating Places on the Earth
Class 6 · Social Science
4 ideas in Class 6 Social Science, explained in plain words, with games and quizzes to practise.
What a Map Is and Its Types
Part of: Maps and Their Components
A map is a flat drawing of an area viewed from directly above. A small area like a school or a large area like a whole country can all be shown on a map. Maps come in different types: physical maps show natural features like mountains and rivers, political maps show countries and their borders, and thematic maps show one specific kind of information.
Why it matters. Without maps we cannot find our way, plan a journey, or understand how places relate to each other. Knowing the types helps children pick the right map for the right purpose.
Try it in two minutes
- Ask your child: if you wanted to find rivers in India, which type of map would you use?
- Show a simple map of your city or town and ask them to point out roads, water bodies and landmarks.
- Ask them to describe what they would see if they looked down at your house from a tall tower.
Try at home. Ask your child to draw a simple map of one room in your house, viewed from above, and label the furniture.
Scale and Direction on Maps
Part of: Maps and Their Components
Scale tells you how much smaller the map is compared to the real area. For example, if 1 cm on a map equals 500 m on the ground, travelling 3 cm on the map means 1,500 m in real life. Direction on a map is usually shown with an arrow pointing north; from north we figure out south, east and west.
Why it matters. Without scale, you cannot judge real distances from a map. Without knowing direction, you cannot navigate — you might walk east when you meant to walk west.
Try it in two minutes
- Show your child a ruler and say: if 1 cm here stands for 100 m in real life, how far is 4 cm?
- Go outside and ask your child to point north (use a compass or the morning sun in the east as a clue). Then ask them to point south, east and west.
- Look at a simple map together and find the north arrow; check if the map matches what you see around you.
Try at home. Use a tape measure and a piece of paper to make a scale map of your street. Decide a scale (for example 1 cm equals 5 m) and draw it out.
Latitudes and the Equator
Part of: The Grid of Latitudes and Longitudes
The Equator is an imaginary line drawn around the middle of the Earth, exactly halfway between the North and South Poles. Latitude measures how far north or south a place is from the Equator. It is expressed in degrees: the Equator is 0 degrees, the North Pole is 90 degrees North and the South Pole is 90 degrees South. Places near the Equator are hot; places near the poles are cold.
Why it matters. Latitudes help us understand climate patterns. Knowing a place's latitude immediately gives a clue about its climate — hot near the Equator, cold near the poles.
Try it in two minutes
- Show a globe or a printed world map and ask your child to find the Equator.
- Ask: if India is around 8 to 37 degrees North, is it nearer to the Equator or the North Pole?
- Ask your child to name one country that is very close to the Equator (e.g. Kenya or Indonesia).
Try at home. Look up the latitude of your city on a globe or map and compare it with a city in a very cold country. Ask: why is one colder than the other?
Longitudes, the Prime Meridian and Time
Part of: The Grid of Latitudes and Longitudes
Longitude lines (called meridians) run from the North Pole to the South Pole. The Prime Meridian passes through Greenwich in London and is marked 0 degrees. Longitude is measured eastward and westward from the Prime Meridian, up to 180 degrees. Because the Earth takes 24 hours to spin 360 degrees, every 15 degrees of longitude equals one hour of time difference. India's Standard Time is 5 hours 30 minutes ahead of Greenwich Mean Time.
Why it matters. Without longitude, we cannot precisely locate any place on Earth or understand why time is different in different countries. Understanding the link between longitude and time helps explain why it is afternoon in India when it is morning in Europe.
Try it in two minutes
- Ask your child: if the Earth takes 24 hours to turn 360 degrees, how many degrees does it turn in one hour? (Answer: 15)
- Look up the current time in London and compare it with the current time in India. Ask your child why they are different.
- On a globe, trace a meridian from the North Pole to the South Pole with your finger.
Try at home. Find out what time it is right now in three cities — New Delhi, London and New York. Ask your child to explain the differences using longitude.
