Read the passage and answer the questions. Meera's uncle lives in London. Every Sunday they talk on a video call. Meera calls at 7:30 p.m. Indian Standard Time. (i) What time is it in London when Meera calls? (ii) Why is there a difference in time? (iii) If her uncle wants to call when it is 9 a.m. in London, what time will it be in India? (5 marks)

Read the passage and answer the questions. A geography teacher showed a globe with lines drawn on it. She pointed out that some lines run east to west and become smaller towards the poles, while others run from pole to pole and are all equal. (i) Name the lines running east to west. (ii) Name the lines running from pole to pole. (iii) Which is the longest east-west line? (5 marks)

Read the passage and answer the questions. India stretches from about 68 degrees E in Gujarat to 97 degrees E in Arunachal Pradesh. The sun rises in Arunachal Pradesh about two hours earlier than in Gujarat, but watches in both states show the same time. (i) Calculate the difference in local time between the two places. (ii) Why do watches show the same time? (iii) Which meridian is used for this purpose? (5 marks)

Read the passage and answer the questions. A researcher travelled from Kenya near the Equator to Norway near the Arctic Circle. In Kenya the sun was almost overhead at noon, while in Norway the sun was low in the sky even in summer. (i) In which heat zone is Kenya located? (ii) In which heat zone is northern Norway located? (iii) Explain why the sun was overhead in one place and low in the other. (5 marks)

Read the passage and answer the questions. A pilot reports his location as 28 degrees N, 77 degrees E, which is close to Delhi. He then flies to 13 degrees N, 80 degrees E, close to Chennai. (i) Which coordinate tells how far north of the Equator a place is? (ii) Which coordinate tells how far east of Greenwich it is? (iii) Find the difference in latitude between the two places. (5 marks)

Draw a labelled diagram of the globe showing the Equator, the tropics, the polar circles and the poles with their latitudes. Explain why these are called important parallels of latitude. (6 marks)

Draw a diagram of the heat zones of the Earth and explain the characteristics of each zone in terms of the angle of the sun's rays and temperature. (6 marks)
