Q1: What is the primary advantage of using a globe in geography studies?
Ans: The main advantage of a globe is that it shows the Earth's shape and how its features are connected in a correct way.
Q2: Name one disadvantage of using a globe for detailed geographic research.
Ans: One problem with a globe is that it cannot show detailed information like towns, cities, or roads.
Q3: Explain the role of the Equator on a globe. How does it divide the Earth?
Ans: The Equator is an imaginary line that splits the Earth into two halves—the Northern and Southern Hemispheres.
Q4: Describe two important parallels of latitude and their significance.
Ans: The Tropic of Cancer and the Tropic of Capricorn are important because they mark the furthest points north and south where the Sun is directly overhead.
Q5: How does longitude relate to time, and why is the Prime Meridian significant in this context?
Ans: Longitude is connected to time because the Earth spins 360° in 24 hours, meaning every 15° of longitude equals a 1-hour time difference. The Prime Meridian (0°) helps define time zones.
Q6: Why do local times differ in places situated on different meridians?
Ans: Local times are different because the Earth rotates, causing the Sun to be in different positions in the sky at different places.
Q7: In India, which longitude is considered the standard meridian, and what is the local time there called?
Ans: In India, the standard meridian is 82.5°E, and the local time is called Indian Standard Time (IST).
Q8: Explain the concept of time zones and how they are defined.
Ans: Time zones divide the Earth into 24 parts, with each part covering 15° of longitude.
Q9: If you were in a place located 30 degrees east of the Prime Meridian, how many hours ahead or behind Greenwich Mean Time (GMT) would your local time be?
Ans: If you are 30 degrees east of the Prime Meridian, your local time would be 2 hours ahead of GMT.
Q10: When it's noon at the Prime Meridian, what time is it along that meridian, and why?
Ans: When it’s noon at the Prime Meridian, it is noon along the entire meridian because all places on that line share the same time.
Q11: What are the heat zones of the Earth, and how are they divided based on latitude?
Ans: The Earth’s heat zones are divided into the Tropical, Temperate, and Polar Zones, based on how far they are from the Equator.
Q12: Explain the characteristics of the zones closest to the Equator in terms of temperature.
Ans: The zones near the Equator are hot and have warm weather most of the time.
Q13: Describe the features of the zones at high latitudes, such as the Arctic Circle and Antarctic Circle.
Ans: The zones near the Arctic and Antarctic Circles are very cold, especially in winter.
Q14: Why do the parallel circles of latitude get shorter as they move toward the poles?
Ans: Circles of latitude get smaller as they move toward the poles because the Earth’s shape gets narrower near the poles.
Q15: How does the tilt of the Earth's axis contribute to the changing seasons on our planet?
Ans: The Earth’s tilt causes different amounts of sunlight to reach different places, leading to the seasons.
Q16: List three advantages of using a globe in geography studies.
Ans: A globe shows the Earth's real shape, explains day and night, and shows how the Earth is tilted on its axis.
Q17: Identify one limitation or disadvantage of using a globe.
Ans: A globe cannot show small details like towns, roads, or cities.
Q18: Explain the significance of the imaginary line known as the axis in a globe.
Ans: The axis is an imaginary line through the center of the globe, showing how the Earth spins.
Q19: How does a globe help us understand the occurrence of day and night?
Ans: A globe shows how the Earth’s rotation causes the Sun to rise and set, helping explain day and night.
Q20: Why can't a globe be used to study specific details like towns, cities, roads, and railways?
Ans: A globe gives a general view of the Earth, so it cannot show the details of small places.
Q21: What is latitude, and how does it run around the Earth?
Ans: Latitude is an invisible line that runs around the Earth from east to west.
Q22: What is longitude, and how does it run around the Earth?
Ans: Longitude is an invisible line that runs from north to south.
Q23: Which line represents the zero-degree latitude, and what is its significance?
Ans: The Equator is the zero-degree latitude line, dividing the Earth into the Northern and Southern Hemispheres.
Q24: What is the Prime Meridian, and where is it located?
Ans: The Prime Meridian is the zero-degree longitude line, passing through Greenwich, UK.
Q25: If the Earth completes one full rotation in 24 hours, how many degrees of longitude does it pass through in one hour?
Ans: The Earth passes through 15 degrees of longitude every hour.
