Q1: What is the purpose of the axis in a globe?
Ans: The axis in a globe helps in its rotation, similar to a spinning top or potter's wheel.
Q2: Name one advantage and one disadvantage of using a globe.
Ans: Advantage: It shows the exact shape of the Earth. Disadvantage: It is difficult to carry.
Q3: What is the largest latitude on a globe?
Ans: The largest latitude is the Equator (0 degrees latitude).
Q4: What do lines of latitude measure on a globe?
Ans: Lines of latitude measure the distance north or south from the Equator.
Q5: How do lines of latitude and longitude intersect on a globe?
Ans: Lines of latitude and longitude intersect at right angles.
Q6: What divides the Earth into the Eastern and Western Hemispheres?
Ans: Longitude, specifically the Prime Meridian, divides the Earth into the Eastern and Western Hemispheres.
Q7: How many degrees does the Earth rotate in one hour?
Ans: The Earth rotates 15 degrees in one hour.
Q8: Which direction does the Earth rotate, and how does it affect local time?
Ans: The Earth rotates from west to east. Going eastward advances local time, while going westward retards it.
Q9: What is the standard meridian for Indian Standard Time?
Ans: The standard meridian for Indian Standard Time is 82.5 degrees East.
Q10: What is the time difference between places 15 degrees apart in longitude?
Ans: The time difference is 1 hour.
Q11: Explain the advantages of using a globe as a model of the Earth.
Ans: A globe accurately represents the Earth's shape, helps understand day-night cycles and seasons, demonstrates the tilt of Earth's axis, and shows the positions of continents and oceans.
Q12: Describe the significance of the Equator on a globe.
Ans: The Equator is the largest latitude and divides the Earth into the Northern and Southern Hemispheres. It's essential for understanding the Earth's geography and climate.
Q13: How do lines of longitude relate to time zones, and why do we have standard time?
Ans: Lines of longitude help define time zones. We have standard time to account for the differences in local time across meridians. It's necessary for coordination and scheduling.
Q14: Explain the concept of time zones in India and the role of the Indian Standard Time.
Ans: India has a single time zone based on the standard meridian at 82.5 degrees East. Indian Standard Time (IST) is used throughout the country to have a uniform time reference.
Q15: Mention some important parallels of latitude other than the Equator.
Ans: Important parallels of latitude include the Tropic of Cancer, Tropic of Capricorn, Arctic Circle, and Antarctic Circle.
Q16: Discuss the advantages and disadvantages of using a globe as a model of the Earth.
Ans: Advantages include accuracy in representing Earth's shape and demonstrating various phenomena. Disadvantages include its size, limited view, inability to study specific regions, and lack of detailed features.
Q17: Explain how lines of longitude and time are interconnected, using examples.
Ans: Lines of longitude help determine time zones. For every 15 degrees of longitude eastward, time advances by 1 hour, and vice versa. For example, New York (74 degrees West) is 5 hours behind Greenwich, while Cairo (31 degrees East) is 2 hours ahead.
Q18: Describe the concept of the Prime Meridian and its significance in dividing the Earth into Eastern and Western Hemispheres.
Ans: The Prime Meridian (0 degrees longitude) runs through Greenwich, London. It divides the Earth into the Eastern and Western Hemispheres. Locations east of the Prime Meridian are in the Eastern Hemisphere, and those west of it are in the Western Hemisphere.
Q19: Explain the role of latitude in defining the Earth's heat zones.
Ans: Latitude plays a crucial role in defining Earth's heat zones. The equator receives the most direct sunlight and is the hottest, while the poles receive the least direct sunlight and are the coldest. The Tropics, Temperate Zones, and Polar Zones are determined by latitude.
Q20: Discuss why standard time is necessary and how it helps in various aspects of life and activities.
Ans: Standard time is necessary to coordinate activities and schedules across regions with different local times. It ensures uniformity and accuracy in communication, transportation, and various aspects of daily life, making global interactions more efficient.
