2,194 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.

C Correct answer
Explanation

This is the correct answer. The correct matching is: a. The wind that blows parallel to a straight isobar is a geotropic wind. b. The wind that circulates around a low is a cyclonic circulation. c. The wind that circulates around a high is an anti cyclonic circulation.

Multiple choice

a. The largest cells extend from the equator to between 30o North and South, and are named Hadley cells. b. The easterlies blow from subtropical high and are named Ferrel cells. c. The westerlies blows towards middle latitudes and are called polar cells.

Multiple choice

What is southern oscillation?

  1. The warming and cooling of oceans

  2. The appearance of warm water off the coast of Peru

  3. The change in pressure condition over Pacific ocean

  4. The pattern of wind circulation in the southern hemisphere

  5. The winds from the tropics converging at low pressure zone
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

El nino causes pressure changes in Central Pacific and Australia. This change in pressure condition over Pacific is known as the southern oscillation.

Multiple choice

Which of the following is/are correct statements?

a. Fronts occur in middle latitudes and are characterised by steep gradient in temperature and pressure. b. Fronts cause abrupt changes in temperature and cause the air to rise to form clouds and cause precipitation. c. Homogenous surfaces, over which front forms, are called the source regions.

Multiple choice

Which of the following statements is/are correct?

a. The cool air of the high plateaus and ice fields draining into the valley is called valley breeze. b. The warm wind on the leeward side of the mountains that carry moisture that condenses and precipitates are called katabatic winds. c. In mountainous regions, the slopes get cooled during the night and the dense air descends into the valley as the mountain wind.

Multiple choice

Which of the following conditions is not favourable for the formation and intensification of tropical storms?

  1. Large sea surface with temperature higher than 27oC

  2. Absence of the Coriolis force

  3. Small variations in the vertical wind speed

  4. A pre-existing weak low-pressure area or low-level-cyclonic circulation

  5. Upper divergence above the sea level system
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is the correct answer. Presence of Coriolis force is favourable for formation and intensification of tropical storms.

Multiple choice

Directions: Read the following information and answer the question that follows.

A certain city is served by subway lines A, B and C and numbers 1, 2 and 3. When it snows, morning service on B is delayed. When it rains or snows, service on A, 2 and 3 are delayed both in morning and afternoon. When temperature falls below 30°F, afternoon service is cancelled in either line A or line 3, but not both. When the temperature rises above 90°F, the afternoon service is cancelled in either line C or line 3, but not both. When the service on line A is delayed or cancelled, service on line C which connects line A, is delayed. When service on line 3 is cancelled, service on line B, which connects line 3, is delayed. On Jan 10, with the temperature at 15°F, it snows all day.

On how many lines will the service be affected, including both morning and afternoon?

  1. 2

  2. 3

  3. 4

  4. 5
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

On Jan 10 with 15°F temperature and snow: Morning delays on B (due to snow) and A, 2, 3 (due to snow). Since temperature is below 30°F, afternoon service is cancelled on either A or 3. Regardless of which is cancelled, A is already delayed in afternoon, and C is delayed (because A is delayed/cancelled). Also, if 3 is cancelled, B is delayed. Counting all affected lines: A, B, C, 2, 3 = 5 lines total.

Multiple choice

Directions: A certain city is served by subway lines A,B and C and numbers 1 2 and 3 When it snows , morning service on B is delayed When it rains or snows , service on A, 2 and 3 are delayed both in the morning and afternoon When temp. falls below 30 degrees Fahrenheit afternoon service is cancelled in either the A line or the 3 line, but not both. When the temperature rises over 90 degrees Fahrenheit, the afternoon service is cancelled in either the line C or the 3 line but not both. When the service on the A line is delayed or cancelled, service on the C line which connects the A line, is delayed. When service on the 3 line is cancelled, service on the B line which connects the 3 line is delayed On Aug 15th with the temperature at 97 degrees Fahrenheit it begins to rain at 1 PM. What is the minimum number of lines on which service will be affected?

  1. 2

  2. 3

  3. 4

  4. 5
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

On Aug 15, temperature 97°F (above 90°F), rain at 1 PM (afternoon): Rain/snow causes delays on A, 2, 3 in afternoon. Above 90°F causes afternoon cancellation on either C or 3. To minimize affected lines, cancel C afternoon. A is delayed (causing C to also be delayed), 2 and 3 are delayed. This affects 4 lines: A, 2, 3, C. If 3 were cancelled instead, B would also be delayed (5 lines affected).

Multiple choice

Which one of the following regions on the surface of earth has Horse Latitudes?

  1. Equatorial low pressure belt

  2. Subtropical high pressure belt

  3. Sub polar low pressure belt

  4. Polar high pressure belt
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Horse Latitudes are located between 30-35 degrees north and south of the equator in the subtropical high pressure belt. These areas are characterized by calm, light winds and were named by sailors who found themselves stranded (and had to throw horses overboard due to lack of water).
