ncert_solutionsQ1. Which are the three essential components of a map?
Answer: Scale, direction, and symbols.
Q2. What is a scale?
Answer: A scale shows the ratio between map distance and actual ground distance.
Q3. What is an atlas?
Answer: An atlas is a book containing a collection of maps.
Q4. What are latitudes?
Answer: Latitudes are imaginary lines running east–west on the Earth.
Q5. Name the heat zones of the Earth.
Answer: Torrid Zone, Temperate Zone, and Frigid Zone.
Q6. What are longitudes?
Answer: Longitudes are imaginary lines running from the North Pole to the South Pole.
Q7. What is the Prime Meridian?
Answer: The Prime Meridian is the 0° longitude passing through Greenwich.
Q8. What is a grid?
Answer: A grid is a network formed by the intersection of latitudes and longitudes.
Q9. What is local time?
Answer: Local time is the time based on the Sun’s position at a particular place.
Q10. What is standard time?
Answer: Standard time is the uniform time used across a country or region.
Q11. What is IST?
Answer: IST is Indian Standard Time based on 82.5°E longitude.
Q12. What is the International Date Line?
Answer: It is a line near 180° longitude that separates two calendar dates.
Q13. What is the importance of a globe?
Answer: A globe shows the Earth’s shape, distances, and directions accurately.
Question 1: Which are the three essential components of a map?
Answer: The three essential components of a map are scale, direction, and symbols.
Question 2: What is a scale? Why is it important?
Answer: A scale is the ratio between distances on the map and the actual distances on the ground. It is important because it helps in measuring real distances from a small map.
Question 3: What is meant by an atlas?
Answer: An atlas is a book containing a collection of maps showing different parts of the world.
Question 4: What are latitudes? Name the heat zones of the Earth.
Answer: Latitudes are imaginary lines running east–west on the Earth. The heat zones are: Torrid Zone, Temperate Zone, and Frigid Zone.
Question 5: What are longitudes? What is the Prime Meridian?
Answer: Longitudes are imaginary lines running from the North Pole to the South Pole. The Prime Meridian (0° longitude) is the main reference line from which longitudes are measured.
Question 6: Define “grid”.
Answer: A grid is a network formed by the intersection of latitudes and longitudes. It helps in locating places accurately.
Question 7: Distinguish between local time and standard time.
Answer:
Local time is based on the position of the Sun at a place and changes with longitude.
Standard time is the same for an entire country or region, chosen using a central meridian.
Question 8: What is Indian Standard Time (IST)?
Answer: IST is the standard time used in India. It is based on 82.5°E longitude and is 5 hours 30 minutes ahead of GMT.
Question 9: What is the International Date Line?
Answer: The International Date Line is an imaginary line near 180° longitude. It separates two calendar dates. Crossing it east to west adds a day; west to east subtracts a day.
Question 10: What is the significance of a globe?
Answer: A globe is the most accurate model of Earth. It shows correct shapes, distances, directions, and land–water distribution.
Answer: A map has three essential components: scale, direction, and symbols. The scale helps us measure actual distances on the ground; for example, 1 cm on a map may represent 1 km in reality. Direction helps us understand the orientation of places using north, south, east, and west. Symbols are used to represent features like roads, rivers, schools, and boundaries. These components make reading maps easier and more accurate.
Answer: Latitudes are imaginary horizontal lines running east–west across the Earth. They measure the distance north or south of the Equator. Based on these latitudes, the Earth is divided into heat zones. The Torrid Zone around the Equator receives the maximum heat. The Temperate Zones have moderate climates as they lie between the tropics and polar circles. The Frigid Zones near the poles receive very little heat and remain extremely cold. These zones explain variations in climate from region to region.
Answer: Longitudes are imaginary vertical lines running from the North Pole to the South Pole. They measure the distance east or west of the Prime Meridian. The Prime Meridian, located at 0° longitude, passes through Greenwich, England, and divides the Earth into eastern and western hemispheres. It is significant because it serves as the reference line for calculating time. All countries determine their standard time based on their distance from the Prime Meridian.
Answer: A grid is a network formed by the intersection of latitudes and longitudes on a map or globe. Each place on Earth has a unique combination of latitude and longitude. By using these coordinates, we can locate any place accurately. For example, if a place is at 20°N latitude and 80°E longitude, it can be precisely identified on both map and globe. Thus, the grid system provides an exact method of finding locations.
Answer: Local time is determined by the position of the Sun at a specific longitude. It differs from place to place; for example, when the Sun is overhead at one location, it may not be overhead at another. Standard time is the uniform time used throughout a country, chosen based on a central meridian to avoid confusion. India uses Indian Standard Time (IST), based on 82.5°E longitude. If India used local time, different states would have different times, causing chaos in travel and communication.
Answer: The International Date Line (IDL) is an imaginary line located near 180° longitude. It separates two consecutive calendar dates. If a traveler crosses the IDL from east to west, they gain a day; if they cross from west to east, they lose a day. The line is not straight because it avoids dividing countries into different dates. Its main significance lies in maintaining a uniform system of dates across the world.
Answer: A globe is considered the most accurate model of the Earth because it represents the planet’s shape, distances, and directions correctly. Unlike flat maps, which distort shapes or sizes due to projection, a globe shows continents, oceans, and landmasses in their true proportions. It also helps in understanding rotation, revolution, and the tilt of the Earth. Therefore, a globe provides a realistic and accurate representation of the Earth.
