1. What is a map?
A map is a representation or drawing of a specific area, such as a village, town, state, or even the whole world, viewed from the top.
2. What are the main components of a map?
The three main components are distance, direction, and symbols.
3. What is an atlas?
An atlas is a collection of maps.
4. What are the types of maps?
- Physical maps: Show natural features like mountains, rivers, and oceans.
- Political maps: Show boundaries, states, and cities.
- Thematic maps: Provide specific information, like population or climate.
5. What does a scale on a map indicate?
The scale represents the ratio between distances on the map and actual distances on the ground.
6. What are cardinal directions?
Cardinal directions are the four main directions: North, East, South, and West.
7. What are intermediate directions?
Intermediate directions are Northeast, Southeast, Southwest, and Northwest.
8. Why do we use symbols in maps?
Symbols help represent features like buildings, roads, and natural landmarks in limited space.
9. What is a globe?
A globe is a spherical model of the Earth or other celestial bodies.
10. What are latitude and longitude?
- Latitude: Measures the distance north or south of the Equator in degrees.
- Longitude: Measures the distance east or west of the Prime Meridian in degrees.
11. What is the Equator?
The Equator is the 0° latitude, an imaginary line dividing the Earth into the Northern and Southern Hemispheres.
12. What is the Prime Meridian?
The Prime Meridian is the 0° longitude, an imaginary line passing through Greenwich, England, dividing the Earth into the Eastern and Western Hemispheres.
13. What is the International Date Line?
The International Date Line is approximately at 180° longitude. Crossing it changes the date by one day.
14. Why do time zones exist?
Time zones exist because the Earth rotates, creating different local times for different longitudes.
15. What is Indian Standard Time (IST)?
IST is 5 hours 30 minutes ahead of Greenwich Mean Time (GMT).
16. How many degrees of longitude represent one hour of time difference?
15° of longitude equals one hour of time difference.
17. Why is the Equator the longest latitude?
The Equator is the widest circle around the Earth, dividing it into two equal halves.
18. What is the latitude of the North and South Poles?
- North Pole: 90°N
- South Pole: 90°S
19. What is the significance of Ujjain in Indian astronomy?
Ujjain was the reference point for India’s ancient prime meridian, known as madhya rekhā.
20. How is longitude related to local time?
Local time changes by one hour for every 15° of longitude.
21. What is the difference between local time and standard time?
- Local time: Specific to a location based on the Sun’s position.
- Standard time: A uniform time for a country or region.
22. Why are time zone boundaries irregular?
They are adjusted to follow political borders and administrative regions.
23. How do maps show elevation?
Maps use contour lines, colors, or shading to represent elevation.
24. What are grid lines on a map?
Grid lines are the intersections of latitudes and longitudes.
25. How do latitude and climate relate?
- Near the Equator: Hot (torrid zone).
- Between the tropics and poles: Moderate (temperate zone).
- Near the poles: Cold (frigid zone).
26. What is Greenwich Mean Time (GMT)?
GMT is the local time at the Prime Meridian.
27. Why do countries like the USA have multiple time zones?
These countries are geographically large and span several longitudes.
28. How many time zones does Russia have?
Russia has 11 time zones.
29. How do you locate a place using latitude and longitude?
A place is identified by its coordinates, e.g., 29°N latitude and 77°E longitude.
30. Why is 180° longitude unique?
It is the same line for both 180°E and 180°W and marks the International Date Line.
31. What is the shape of the Earth?
The Earth is an oblate sphere, slightly flattened at the poles.
32. What are parallels of latitude?
Parallels of latitude are imaginary east-west lines, parallel to the Equator.
33. What are meridians of longitude?
Meridians of longitude are imaginary north-south half-circles connecting the poles.
34. How is the Earth’s rotation connected to time zones?
The Earth’s 360° rotation in 24 hours divides time zones into 15° segments, each representing one hour.
35. Why are symbols standardized on maps?
Standard symbols ensure maps are universally understood.
36. What is a thematic map?
A thematic map provides information on specific themes, like population density or climate.
37. Why are globes more accurate than flat maps?
Globes represent the Earth’s spherical shape, avoiding distortions seen in flat maps.
38. What happens when you cross the International Date Line eastward?
You subtract one day from the calendar.
39. What happens when you cross the International Date Line westward?
You add one day to the calendar.
40. How is longitude measured?
Longitude is measured in degrees from the Prime Meridian, up to 180°E or 180°W.
Suggested Activities:
- Draw maps of your locality with symbols and directions.
- Use a globe or atlas to find coordinates of major cities like Delhi and Mumbai.
- Calculate time differences using longitude values.
