Which of the statements(s) given above is/are correct?
a) Only 1 b) Only 2 c) Both 1 and 2 d) Neither 1 or 2
Ans: (a)
Explanation: [The coriolis force is responsible for deflecting winds towards the right in the northern hemisphere and towards the left in the southern hemisphere. Hence the correct answer is option a)]

#### Q2. Consider the following statements:

1. The oceans in the southern hemisphere record relatively high average temperature than in the northern hemisphere.
2. The average annual temperature of all the oceans is 17.20 c.
Which of the statements(s) given above is/are correct?
a) Only 1        b) Only 2        c) Both 1 and 2         d) Neither 1 or 2
Ans: (b)
Explanation: [The oceans in the northern hemisphere record relatively high average tempereture than in the southern hemisphere. Hence, the correct answer is option b)]

#### Q3. Which of the following statements is not correct?

a) Temperature decreases with height in mesosphere.
b) Temperature increases with height in stratosphere.
c) Jet aircrafts fly in troposphere.
d) None of the above
Ans: (c)
Explanation: [Jet aircrafts often fly through the lower stratosphere because it provides easiest flying conditions. Hence, the correct answer is option c)]

#### Q4. Which of the following statements is incorrect about Tropical cyclones?

a) They develop over oceans.
b) They are characterized by circular and asymmetrical isobars.
c) They have very high pressure at the centre.
d) They move from east to west with the trade winds.
Ans: (c)
Explanation: [Tropical cyclones have very low pressure at the centre and the pressure gradient is very steep and winds are very strong. Hence, the correct answer is option c)]

#### Q5. Match the following:

#### Q6. Which of the following is the longest day of the year for the northern hemisphere?

a) 21 June b) 21 March c) 23 September d) 22 December
Ans: (a)
Explanation: [On 21 June the sun is overhead at the Tropic of Cancer and it is the longest day of the year for the northern hemisphere. On 21 March and 23 September the sun is overhead at the equator and the lengtho the day and night is same everywhere throughout the world. This positio of the earth is called equinon. On 22 December the sun is overhead at the Tropic of Capricorn and the southern hemisphere receives the maximum daylight. Thus, correct answer is option a)]

#### Q7. Consider the following statements:

1. The atmosphere near the year is thinner.
2. The temperature contrast between continents and ocean is greater during summer than winter.
Which of the above given statements is/are correct?
a) Only 1 b) Only 2 c) Both 1 and 2 d) Neither 1 or 2
Ans: d) Explanation: [The atmosphere near the surface is denser & contains large amount of water vapour and dust particles. The temperature contrast between continents & oceans Is greater during winter than summer. Hence, correct answer is option d)]

#### Q8. Consider the following statements:

1. Ozone is found in the upper layer of Troposphere.
2. Ozone absorbs ultra-violet rays and thus protects life from these harmful rays
Which of the statements(s) given above is/are correct?
a) Only 1 b) Only 2 c) Both 1 and 2 d) Neither 1 or 2
Ans: (b)
Explanation: [Ozone is found in very small fraction in the stratosphere between 20 and 25 km from the earth’s surface. Hence, the correct answer is option b)]
