Test: Latitudes & Longitudes - Question 3

The mid-day sun never shines overhead on any latitude beyond the

Detailed Solution for Test: Latitudes & Longitudes - Question 3

The sun is never overhead beyond the tropics due to the latitudes. The sun's rays always fall directly at 0° latitude which is known as the equator. The sun rays can be experienced overhead till the tropic of cancer and Capricorn in the northern and southern hemispheres of the earth respectively.

Test: Latitudes & Longitudes - Question 4

Which of the following is the prime meridian of India?

Detailed Solution for Test: Latitudes & Longitudes - Question 4

In India, the longitude of 82½° E (82° 30'E) is treated as the standard meridian. The local time at this meridian is taken as the standard time for the whole country. It is known as the Indian Standard Time (IST).

Test: Latitudes & Longitudes - Question 5

At which angle the meridians of longitudes drawn to the Equator from the North Pole to the South Pole?

Detailed Solution for Test: Latitudes & Longitudes - Question 5

Meridians of longitude are drawn from the North Pole to the South Pole and are at right angles to the Equator. 

Test: Latitudes & Longitudes - Question 6

On which of the following latitude, the mid-day sun is exactly overhead at least once a year?

Detailed Solution for Test: Latitudes & Longitudes - Question 6

The mid-day sun is exactly overhead at least once a year on all latitudes in between the Tropic of Cancer(23 ½ ⁰N) and the Tropic of Capricorn(23 ½ ⁰). This area, therefore, receives the maximum heat and is called the Torrid Zone. So clearly the answer is 22⁰N.

Test: Latitudes & Longitudes - Question 7

Consider the following statement:
1. The mid-day sun never shines overhead on any latitude beyond the Tropic of Cancer and the Tropic of Capricorn.
2. The angle of the sun’s rays goes on increasing towards the poles.
Which of the statements given above is/ are correct?

Detailed Solution for Test: Latitudes & Longitudes - Question 7

Statement 1 is correct. The Tropic of Cancer and the Tropic of Capricorn mark the furthest points north and south, respectively, where the sun can be directly overhead. Beyond these latitudes, the mid-day sun will never shine directly overhead.

Statement 2 is incorrect. The angle of the sun's rays actually decreases towards the poles, not increases. This is because the Earth's curvature causes the sun's rays to be more spread out at higher latitudes. 
Therefore, the correct answer is 3) 1 only.

Test: Latitudes & Longitudes - Question 8

Areas lying between the Arctic Circle and the North Pole in the Northern Hemisphere and the Antarctic Circle and the South Pole in the Southern Hemisphere are very cold because?

Detailed Solution for Test: Latitudes & Longitudes - Question 8

The correct answer is 2 "The sun does not rise much above the horizon".

Explanation:


1. Low Sun Angle: Areas lying between the Arctic Circle and the North Pole in the Northern Hemisphere and the Antarctic Circle and the South Pole in the Southern Hemisphere are very cold because the Sun is at a low angle in the sky. This means that the Sun's rays hit the Earth at a more oblique angle, spreading the energy over a larger area and reducing the intensity of the heat.

2. Limited Daylight Hours: In addition, these areas have very limited daylight hours for much of the year, particularly in winter when the Sun may not rise above the horizon at all. This means that there is less time for the Sun's energy to warm the Earth in these regions.

3. Reflection of Sunlight: A significant portion of the Sun's rays are reflected back into space by the ice and snow that cover these regions. This further reduces the amount of solar energy that is absorbed and converted into heat.

4. Distance from the Sun: Although it is a lesser factor than the angle of the Sun's rays and the amount of daylight, the polar regions are also slightly further away from the Sun due to the Earth's tilt, which can contribute to the colder temperatures.

Test: Latitudes & Longitudes - Question 9

Which of the following city lies on the east side of the Indian standard meridian?

Detailed Solution for Test: Latitudes & Longitudes - Question 9

Kolkata is located east side of the Indian standard meridian.

Test: Latitudes & Longitudes - Question 10

As the earth rotates from west to east, those places east of Greenwich will be

Detailed Solution for Test: Latitudes & Longitudes - Question 10

As the earth rotates from west to east, those places east of Greenwich will be ahead of Greenwich time and those to the west will be behind it.
