Short Questions: Globe: Latitudes & Longitudes | NCERT Summary: UPSC PDF Download

Q1: What does the Earth look like? What is its shape?
Ans:

• The Earth looks like an orange. It bulges on the sides and is slightly flat on the top and at the bottom.
• Its true shape is geoid which means earth – like shape.
• A globe is the three dimensional model of the Earth.

Q2: What is the use of Globes?
Ans: On globes, countries, continents and oceans are shown in their correct shape. Distance and directions are also shown correctly on the globe. The extent of relief features is correct.

Q3: Define local time.
Ans: Local Time:

• Local time is calculated by the position of the Sun at noon of a given place.
• It bases on the local meridian passing through that place.
• When the Sun is exactly overhead at that meridian, it is 12 noon.
• The places lying North and South on the same meridian will have the same local time. On the otherhand the places lying East or West of that meridian have different local times.

Q4: What is a globe? What are its types?
Ans: Globe is the three dimensional model representing the true shape of the Earth.
Globes are of various sizes and types:

• Big Size Globe. Can not be carried easily.
• Small Pocket Globe
• Balloon Like Globe. They can be inflated and are handy and carried with ease.

Q5: What are longitudes?
Ans: Longitudes:

• Angular distance from the Prime Meridian is termed as longitude.
• Lines joining the North Pole and the South Pole are called the lines of longitude.
• They are also called meridian because noon occurs at the same time at places located on a line of longitude.

Q6: Write the position of North Temperate Zone.
Ans: From the Tropic of Cancer (about 23.5° north latitude) to the Arctic Circle (roughly 66.5° north latitude), the north temperate zone exists.

Q7: How pole star can be useful to find latitude?
Ans: For example, the Pole star will be around 52 degrees above the horizon from southern England, indicating a latitude of 52 degrees north. Near the North Pole, Polaris will be straight overhead, while at the Equator, it will be on the horizon.

Q8: Why equator is important?
Ans: The equator serves as a reference point for locating various locations.

Q9: What is Prime Meridian?
Ans: The Prime Meridian is said to be the reference point, with a longitude of 0 degrees. We have 180 degrees eastward and 180 degrees westward from this prime Meridian. The earth is supposed to be divided into equal halves by the prime meridian and the 180 degree meridian.

Q10: What are latitudes?
Ans: Longitudes are perpendicular lines to the equator, while latitudes are parallel lines to the equator. Knowing the latitude and longitude of any spot on the globe makes it simple to locate it.

Q11: What is the importance of the globe?
Ans: On a little ball, the globe allows us to comprehend the entire planet. It aids in the proper comprehension of various aspects of the world.

Q12: Why do you think temperate zone has moderate climate conditions?
Ans: Since it is located away from the equator, the temperate zone features mild climatic conditions.

Q13: Where does the Frigid Zone lie?
Ans: The coldest zones are the frigid zones. Near the poles is the Frigid Zone. This is the area between the Arctic Circle and the North Pole in the northern hemisphere. This is the area between the Antarctic Circle and the South Pole in the southern hemisphere. The sun rays are continually slanting in this direction, and there is very little heat.

Q14: Which are the four parallel latitudes?
Ans: There are four key latitude parallels. The Tropic of Cancer is located in the northern hemisphere, the Tropic of Capricorn is located in the southern hemisphere, the arctic circle is located at 66 degrees north of the equator, and the Antarctic Circle is located at 66 degrees south of the equator.

Q15: What is 0° Meridian?
Ans: All countries agreed that the meridian that passes through Greenwich, where the British Royal Observatory is located, is the starting point for counting longitudes. The Prime Meridian was defined as a meridian with a value of 0 degrees.
