Class 5 SST HOTS Questions - The Earth-Our World

Q1: What is the actual shape of the Earth?
Ans: The Earth is not flat; it is an oblate spheroid. It is slightly flattened at the poles and bulges at the Equator.

Q2: What are the two important tools used for the study of the Earth?
Ans: (1) Maps and (2) Globes.

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

Q4: Which is the largest globe in the world?
Ans: The largest globe in the world is Eartha. It is located in Yarmouth, USA.

Q5: What are the features of latitudes?
Ans:

• Latitudes are parallel to each other and run from east to west direction.
• Latitudes have equal distances between them everywhere.
• All the latitudes are complete circles, except the North and South Pole, which are points.
• The length of the latitudes decreases from the Equator to the poles.

Q6: What are the features of longitudes?
Ans:

• Longitudes are semi-circles that run between the poles from north to south.
• Longitudes have the largest space between them at the Equator and converge at the poles.

Q7: What do you understand by the Global Grid?
Ans: The network of latitudes and longitudes is called the global grid. This grid is used to locate any place on the Earth.

Q8: What are the important latitudes?
Ans:

• North Pole (90° N)
• Arctic Circle (66.5° N)
• Tropic of Cancer (23.5° N)
• Equator (0°)
• Tropic of Capricorn (23.5° S)
• Antarctic Circle (66.5° S)
• South Pole (90° S)

Q9: What is an international date line?
Ans: The 180° East and the 180° West longitudes meet and form a single line on the opposite side of the world. This line is called the 180° longitude or the international dateline.

Q10: What is the other name for latitudes?
Ans: Latitudes are also known as parallels.

Q11: What is the angle between the latitudes and longitudes?
Ans: The latitudes and longitudes intersect at right angles, which is 90°.

Q12: What is a hemisphere? Which lines divide the Earth into hemispheres?
Ans: A hemisphere is one half of the Earth. The Equator divides the Earth into the Northern and Southern Hemispheres, while the Prime Meridian divides it into the Eastern and Western Hemispheres.

Q13: What are the differences between latitudes and longitudes?
Ans: Latitudes are horizontal circles running from west to east, while longitudes are vertical semi-circles running from north to south.

Q14: What is a global grid and what is its use?
Ans: The global grid is the network of latitudes and longitudes used to locate any place on Earth accurately. It is essential for navigation and mapping.
