Short & Long Questions: Latitudes and Longitudes | Be an Explorer 5: Book Solutions, Notes & Worksheets - Class 5 PDF Download

Short Answer Questions.

Q1: What is the shape of the Earth?
Ans: The Earth is spherical in shape.

Q2: What is the imaginary line around which the Earth rotates?
Ans: The Earth rotates on an imaginary line called the axis.

Q3: What is the angle of tilt of the Earth's axis?
Ans: The Earth's axis is tilted at an angle of 23.5 degrees.

Q4: What is the North Pole and the South Pole?
Ans: The northernmost part of the axis is the North Pole, and the southernmost part is the South Pole.

Q5: What is the Equator, and where is it located?
Ans: The Equator is a latitude line that divides the Earth into Northern and Southern Hemispheres. It is marked as 0° latitude.

Q6: Name two important latitudes apart from the Equator.
Ans: Tropic of Cancer (23.5° N) and Tropic of Capricorn (23.5° S).

Q7: What are the Arctic and Antarctic Circles also known as?
Ans: They are also known as Polar Circles.

Q8: How many parallels are there, and where is the longest one located?
Ans: There are 181 parallels, and the Equator forms the longest line.

Q9: What are meridians, and what is the Prime Meridian?
Ans: Meridians are imaginary lines running from North to South. The Prime Meridian (0°) passes through Greenwich, near London.

Q10: How are latitudes and longitudes useful in locating places?
Ans: Latitudes and longitudes form a grid, helping us locate places on the Earth.

Long Answer Questions.

Q1: Explain the concept of latitudes and their characteristics.
Ans: Latitudes are horizontal lines running from east to west on the Earth. They are circles that never touch, with the Equator (0°) being the longest. The distance between latitudes decreases towards the Poles.

Q2: Describe the importance of the Equator and its role in dividing the Earth.
Ans: The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere. It is crucial for understanding locations and directions on the globe.

Q3: List and explain the characteristics of meridians.
Ans: Meridians are semi-circular lines running from North to South. There are 360 meridians, with the Prime Meridian (0°) dividing the Earth into Eastern and Western Hemispheres. They are of the same length, meeting at the Poles.

Q4: Differentiate between parallels and meridians.
Ans: Parallels are horizontal circles, while meridians are vertical semi-circular lines. Parallels are parallel to each other and decrease in length towards the Poles, while all meridians are of the same length and meet at the Poles.

Q5: How do latitudes and longitudes help in locating places on the globe?
Ans: Latitudes and longitudes form a grid on the Earth. The intersection of these lines indicates the location of a place, helping us identify and navigate on maps and globes.

Q6: Explain the significance of the Tropic of Cancer and the Tropic of Capricorn.
Ans: The Tropic of Cancer and Tropic of Capricorn are latitudes located at 23.5 degrees N and S, respectively. They mark the northernmost and southernmost points where the Sun appears directly overhead, influencing climate and seasons.

Q7: What is the International Date Line, and why is it significant?
Ans: The International Date Line is at 180° E/W meridian. It is where a new day begins, and it helps prevent confusion in timekeeping as one moves from the Eastern Hemisphere to the Western Hemisphere.

Q8: Discuss the role of latitudes and longitudes in Hipparchus' system of dividing a circle.
Ans: Hipparchus adopted the Babylonian system of dividing a circle into 360 degrees, and this system is still used today for marking longitudes or meridians. Latitudes and longitudes play a crucial role in this division.

Q9: Why are the Arctic and Antarctic Circles also called Polar Circles?
Ans: These circles are located at 66.5° N and S latitudes, marking the areas where, at least once a year, there is continuous daylight for 24 hours (during summer) or continuous darkness for 24 hours (during winter).

Q10: Explain how the Equator and Prime Meridian help in dividing the Earth.
Ans: The Equator divides the Earth into the Northern and Southern Hemispheres, while the Prime Meridian divides it into the Eastern and Western Hemispheres. Together, they form a reference grid for locating places on the globe.
