2,121 Questions

Climate, weather, and geography examine temperature variations, wind patterns, atmospheric hazards, and global climate zones. This hub addresses climographs, thunderstorm triggers, and regional climate descriptors. These concepts are essential for UPSC, SSC, and RRB general studies and geography exams.

  1. the polar high

  2. the equatorial low

  3. the subtropical high

  4. cyclonic circulation

  5. the general circulation of the atmosphere
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The wind circulation around a low is called cyclonic circulation.

Multiple choice

On which of the following the pattern of planetary winds does not depend?

  1. The latitudinal variation of atmospheric heating.

  2. The emergence of pressure belts.

  3. The migration of belts following apparent path of the sun.

  4. The distribution of continents and oceans.

  5. The gravitational pull.
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

 It depends upon the rotation of the earth. It does not depend upon the gravitational pull. Thus, this is the correct answer.

Multiple choice

Which of the following is correct about westerlies?

  1. The cells from which westerlies arrive are called Ferrel cells.

  2. Hadley cells are the source for westerlies.

  3. Polar cells blowing towards the middle latitudes cause the westerlies.

  4. The transfer of heat energy from lower latitudes to higher latitudes causes the westerlies.

  5. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This is the correct answer. Westerlies are caused by Ferrel cells. In the middle latitudes the circulation is that of sinking cold air that comes from the poles and the rising warm air that blows from the subtropical high. At the surface these winds are called westerlies and the cell is known as the Ferrel cell.

Multiple choice

Which of the following is not a type of air mass?

  1. Maritime tropical (mT)

  2. Continental tropical (cT)

  3. Maritime polar (mP)

  4. Continental polar (cP)

  5. Maritime arctic (mA)
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is incorrect. The recognszed air mass is continental arctic or cA along with the others mentioned above.

Multiple choice

Which of the following is/are correct about El Niño? a. The appearance of the warm water of Central Pacific ocean off the coast of Peru. b. The change in pressure condition over Pacific, is known as southern oscillation. c. It is used for long range weather forecasting in major parts of the world.

  1. Only a

  2. Only b

  3. Only c

  4. Only a and b

  5. Only b and c
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This is the correct answer. Both these statements are correct about El Nino.

Multiple choice

Which of the following is correct about cumulus clouds?

  1. The cold front moves faster than the warm front ultimately overtaking the warm front, which is completely lifted up and the front is occluded and the cumulus clouds are formed.

  2. If an air mass is fully lifted above the land surface, it causes cumulus clouds.

  3. The cold front approaches the warm air from behind and pushes the warm air up resulting in the development of cumulus clouds along the cold front.

  4. All of the above.

  5. None of the above.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This is correct about cumulus clouds.

Multiple choice

Which of the following statements is/are correct? a. During the night in the mountainous regions the slopes get cooled and the dense air descends into the valley as the katabatic wind. b. The cool air of the high plateaus and ice fields draining into the valley is called the adiabatic wind. c. During the day the slopes get heated up and air moves upslope to fill the resulting gap, this is called the valley breeze.

  1. Only a

  2. Only b

  3. Only c

  4. Only a and b

  5. All of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

This statement is correct. In mountainous regions, during the day the slopes get heated up and air moves upslope and to fill the resulting gap the air from the valley blows up the valley. This wind is known as the valley breeze.

Multiple choice

Which of the following is/are the source(s) of formation of air masses?

  1. Siberian plain

  2. Equatorial forest

  3. Sahara desert

  4. Only 1 and 3

  5. None of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

This is the correct answer. There are five major source regions. These are warm tropical and subtropical oceans, the subtropical hot deserts, the relatively cold high latitude oceans, the very cold snow covered continents in high latitudes and the permanently ice covered continents in the Arctic and Antarctica.

Multiple choice

Which of the following statements is/are correct? a. A mature tropical cyclone is characterised by the strong spirally circulating wind around the centre, called the eye. b. The cyclones, which cross 20oN latitude generally, recurve and peter out. c. From the eye wall rain bands may radiate and trains of cumulus and cumulonimbus clouds may drift into the outer region.

  1. Only a

  2. Only b

  3. Only c

  4. Only a and b

  5. Only a and c
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This is the correct answer, as both a and b are correct.

Multiple choice

Which of the following statements is/are incorrect? a. The fronts occur in middle latitudes and are characterised by steep gradient in temperature and pressure. b. The fronts bring abrupt changes in temperature and cause the air to rise to form clouds and cause thunderstorms. c. When two different air masses meet, the boundary zone between them is called a front.

  1. Only a

  2. Only b

  3. Only c

  4. All of these

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This statement is incorrect. The fronts bring abrupt changes in temperature and cause the air to rise to form clouds and cause precipitation, not thunderstorms. Hence, this option is the answer.

Multiple choice

Which of the following statements is/are incorrect? a. The warm air, of the high plateaus and ice fields draining into the valley is called katabatic wind. b. Katabatic winds melt the snow in a short time. c. Adiabtic process helps the warm winds to melt the snow.

  1. Only a

  2. Only b

  3. Only c

  4. Only a and b

  5. Only a and c
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Both these statements are incorrect. a. The cool air, of the high plateaus and ice fields draining into the valley is called katabatic wind. b. The warm winds blowing on the leeward side of the mountain ranges gets warmed up by adiabatic process. This melts the snow in a short time.

Multiple choice

'Cirrus' means

  1. low cloud

  2. high cloud

  3. rain bearing cloud

  4. light cloud
Reveal answer Fill a bubble to check yourself
