The total length of Earth’s equator is about –
Correct Answer:
(C)
40,000 km.
The equator usually refers to an imaginary line, on the Earth surface at equal distance from the North Pole and the South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. The total length of the Equator is 40090 Km length (approximately 24,901 miles). 78.7% of the line passes through water while 21.3% passes through land. Therefore, option (c) can be taken as the correct answer.

Correct Answer:
(D)
Equator
Two types of solstices occur in a year (i) Summer Solstice (ii) Winter Solstice. The sun reaches at tropic of Cancer in the month of June in Northern hemisphere and the Summer solstice takes place and just opposite to it in Southern hemisphere, Winter Solstice takes place. At the time of summer solstice longest day and shortest night occur in Northern hemisphere, but in the Southern hemisphere shortest day and largest night occur. At the same time, there is no much difference in days and nights at the Equator. Therefore option (d) is the correct answer.

The time at Cairo is 2 hours ahead of Greenwich. Hence, it is located at-
Correct Answer:
(B)
30° E longitude
Cairo (Egypt) is located at 30° 3’N latitudes and 31° 14’ E longitude. Time of Cairo is 2 hours ahead of Greenwich. Therefore, its position approximately falls near the 30° East longitude. The Earth being spherical in shape rotates on its axis by 360° in 24 hours. Therefore, its movement for 1° of longitude takes the time of 4 minutes. So, it can be easily calculated that in 120 minutes ( 2 hours) angle for longitude will be 30° , Therefore, option (b) should be the correct answer.
