Thnkiew sir for ur valuable advice.... i think....it will help me a lot
There seem to be a mistake in Q 108. I mean, why should all latitudes and longitudes meet at the poles? The statement 2 is incorrect, right?
no. longitudes converge at poles and latitude too. so the statement is correct.

the question talks about intersection @saswati. A latitude and longitude, as lines, when intersect they are perpendicular to each other.

sir I have a query . In ques no. 109 u said traveling from east to west i.e from north america to russia BT north america is located at west and Russia at east so it should be from Russia to north america . plzzzz do reply n solve my query
The International Date Line sits on the 180º line of longitude in the middle of the Pacific Ocean, and is the imaginary line that separates two consecutive calendar days. It is not a perfectly straight line and has been moved slightly over the years to accommodate needs (or requests) of varied countries in the Pacific Ocean. Immediately to the left of the International Date Line, the date is always one day ahead of the date (or day) immediately to the right of the International Date Line in the Western Hemisphere.

By east to west he meant the direction of movement. Suppose you are in Canada, and then you move towards Alaska, then you are moving east to west, as Canada lies to the east of Alaska. Similarly, to get to Russia, you need to go west from North America. In the process, if you cross the IDL, the date increases by one.

person who goes around the world from east to west (the same direction as Magellan's voyage) would gain or set their clock back one hour for every 15° of longitude crossed, and would gain 24 hours for one circuit of the globe from east to west if they did not compensate by setting their clock forward one day when they crossed the IDL. In contrast, a west-to-east circumnavigation of the globe loses an hour for every 15° of longitude crossed but gains back a day when crossing the IDL. The IDL must therefore be observed in conjunction with the Earth's time zones: on crossing it in either direction, the calendar date is adjusted by one day
Jp
from east to west(left movement) loss of one day this implies date will increase by one.... means one day will be completely gone.....(just remember LEFT =LOSS)......ONE DAY LOSS MEANS DATE WILL INCREASE Q 102.....YES interior part of the outer planets is liquid.

but in slides west to east is said to have loss of one day.. Please clear the confusion.
Jp
west to east(russia to north america)----one day gain but date will decrease by one ,,,,,sir used the phrase (weightloss)means W TO E ---LOSS of date by one ,do not confuse with day---- it means date will decrease by one but u will gain one day, its loss of DATE not DAY, both the explanations are correct,u can choose either one.
Thank you Roman sir........... Thanks to unacademy.......... Please make a course on class 7 ncert of geography through mcq as you had explained for class 6..... This will be very helpful for us....
hey....deep request to make MCQ for whole ncert geography just like class 6 ncert you have made...pls request
1. 101. Consider the following statements: 1. Mercury takes the shortest time to rotate and revolve around the Sun. 2. One Martian day is roughly the same as a day on Earth. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

2. Solution: (b) Mercury takes the shortest time to revolve around the Sun (88 days) but not for rotation. Jupiter takes the shortest time for rotation. Earth takes 23 h 56 m and 4s to complete one spin and Mars takes 24h and 40m to spin on its axis. So, one Martian day is almost the same as one Earth day.

3. 102. Consider the following statements: 1. All outer planets are made up of gases and liquids. 2. All outer planets rotate faster than all inner planets. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

4. Solution: (c) All outer planets are made up of gases and hence called gaseous planets or Jovian planets while inner planets are made up of rocks mostly and hence called terrestrial planets. All outer planets rotate faster than the Sun as they are farther away from the Sun and experience weaker gravitational force of the Sun

5. 103. Consider the following statements: 1. All planets move around the Sun in circular orbits. 2. All planets have retrograde rotation. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

6. Solution: (d) All planets move around the Sun in elliptical orbits. Rotation from East to West is called retrograde rotation. Only two planets have retrograde rotation, Venus and Uranus. All other planets have prograde rotation or rotation from West to East.

7. 104. Consider the following statements: 1. Earth is the largest inner planet. 2. Mercury is the hottest planet of the Solar system. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

8. Solution: (a) Earth is the largest inner planet and 5th largest planet in the Solar system Though Mercury is closest to the Sun, it is not the hottest planet as there is no atmosphere to trap greenhouse gases. Being covered in clouds, Venus is the hottest and the brightest planet of the Solar system due to its reflection and greenhouse gas effect.

9. 105. Consider the following statements: 1. Saturn is the most oblate planet in the Solar system. 2. Cassini is the first probe to enter the orbit of Saturn. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

10. Solution: (c) Oblate means equatorial diameter is longer than polar diameter which is more for Saturn than other planets. Cassini-Huygens spacecraft was launched to Saturn in 1997 and arrived there in 2004. It will be deorbited in September, 2017.

11. 106. Consider the following statements: 1. Latitude is the arc subtended by an angle at the Earth's centre. 2. The distance per degree of latitude is same from equator to poles. 3 1 latitude measures 111 km. Select the correct answer using the code given below: (a) 1 and 2 only (b) 2 and 3 only (c) 1 and 3 only (d) All of the above

12. Solution: (c) Latitudes are arcs subtended by angle at the Earth's centre. The distance from Equator to poles is 10,013 kms which when divided by 90 gives 111 kms for 1 degree latitude. But the distance of latitudes varies from equator to poles because of the shape of the Earth. It is flattened at the poles. So distance is larger at the poles than at the Equator.

13. D Solution: (d) Solution:(d) In spite of its vast geographical extent, China decided to follow a single time zone for unifying its country and its people soon after the Communist Party assumed power. Since all longitudes converge at North and South pole, they have no time zone. Research stations follow the time of their countries or from where they set off their expedition. ISS follows Greenwich Mean time.

14. 109. What happens when you cross the International Date Line travelling from its east to west? (a) Date increases by one. (b) Date decreases by one. (c) Day remains the same. (d) Day goes backward by one.

15. Solution: (d) Australia is 2/3rd covered with deserts. Great Basin, Sonoran and Mojave are deserts of North America. Atacama and Patagonian are deserts of South America.

16. 111. Consider the following statements: 1. During equinox, days and nights are equal throughout the world. 2. During equinox, circle of illumination cuts through the poles. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

17. Solution: (c) During equinox, Sun is overhead at the equator making days and nights equal throughout the world. Since, circle of illumination is the line that divides days and nights, it will cut through the poles during equinox as poles are not inclined towards the Sun during this time.

18. 113. Consider the following statements: 1. Narmada flows between Vindhayas and Satpuras. 2. Narmada and Tapti rivers flows from West to East. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

19. 114.The shallowest of the world's oceans is? (a) Pacific Ocean (b) Indian Ocean (c) Arctic ocean (d) Atlantic Ocean

20. 115. Consider the following statements: 1. Arctic Ocean is located within the Artic Circle. 2. Arctic Ocean is connected to the Atlantic Ocean through the Beaufort Sea. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

21. Solution: (a) Arctic Ocean is located within the Arctic Circle. It is connected to the Atlantic Ocean through Greenland Sea and Labrador Sea. It includes Beaufort Sea as its part.

22. 116. Arrange the rivers in the North South direction: 1. Jhelum 2. Sutlej 3. Chenab 4. Ravi Select the correct answer using the code given below: (a) 1, 2, 3,4 (b) 2, 4, 3, 1 (c) 1, 3, 4, 2 (d) 2, 4, 1, 3

23. Solution: (c) The rivers from North to South are Jhelum, Chenab, Ravi and Sutlej.

24. 118. Which of the following processes form(s) mountains? 1. Volcanic eruption 2. Folding Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) None

25. Solution: (d) The correct sequence of cities in the North South direction is Agartala, Gandhinagar and Kolkata.

26. 121. The hot and dry winds which blow over the plains of India and Pakistan are called? (a) Chinook (b) Foehn (c) Loo (d) Khamsin

27. Solution: (c) Hot and dry winds have different names in different parts of the World. Chinook in Rocky mountains in North America. Foehn over Alps and North Italy. Loo in India and Pakistan. Khamsin in Egypt.

28. 124. Consider the following statements: 1. Half of the mass of the Earth's atmosphere lies in Troposphere. 2. The height of tropopause varies over Equator and poles. Select the correct answer using the code given below: (a) 1 only (b) 2 only (c) Both 1 and 2 (d) Neither 1 nor 2

29. Solution: (d) There are no deltas on the Western coast as they are narrow and steep and do not help in delta formation. Hence, they are natural harbors while the slope is gradual in Eastern Coast which enables delta formation and harbors are made artificially
