Climate, Weather, and Geography

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.

Climate, Weather, and Geography Questions

Multiple choice

The tropical cyclones do not occur close to the equator because of

  1. weak coriolis force

  2. light and variable winds

  3. excessive humidity

  4. convective activity

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Coriolis force is zero at the equator and increases toward the poles. Tropical cyclones require the Coriolis force to initiate the rotation of the air mass; without it, the low-pressure system cannot develop into a cyclone.

Multiple choice

Consider the following statements :

  1. General characteristics of westerlies are largely modified by cyclones and anticyclones.
  2. Westerlies are the most dominant wind systems in middle latitudes.
  3. Westerlies become more vigorous in the southern hemisphere. Which of the statements given above is/are correct?

  1. 1 and 2 only

  2. 2 only

  3. 1 and 3 only

  4. 1,2 and 3

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All three statements are correct: westerlies are modified by pressure systems, they dominate the middle latitudes, and they are stronger in the Southern Hemisphere due to the lack of large landmasses to create friction.

Multiple choice

Consider the following statements :

  1. The decrease of temperature with increasing latitude is more pronounced in north Atlantic ocean than the south Atlantic ocean.

  2. The vertical distribution of temperature in enclosed seas of higher latitudes registers inversion of temperature.

Which of the statements given above is/are correct?

  1. 1 only

  2. 2 only

  3. Both 1 and 2

  4. Neither 1 nor 2

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The North Atlantic has more landmasses and complex currents, leading to more pronounced temperature gradients. In enclosed seas at high latitudes, surface cooling can lead to denser water sinking, causing temperature inversion.

Multiple choice

With reference to Koppen's classification of climatic types, consider the following statements :

  1. The minor/sub type indicated through small letter ? means rains all the year round.

  2. The minor/sub type indicated through small letter ? means dry summer.

Which of the statements given above is/are correct?

  1. 1 only

  2. 2 only

  3. Both 1 and 2

  4. Neither 1 nor 2

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In Koppen's classification, 'f' stands for 'feucht' (moist), meaning rain throughout the year. 's' stands for 'sommertrocken' (summer dry), meaning a dry summer season.

Multiple choice

Consider the following places :

  1. San Francisco
  2. Adelaide
  3. Cape Town
  4. Sydney Which of the above have Mediterranean climate?

  1. 1 and 3 only

  2. 2 and 4

  3. 1,3 and 4

  4. 1,2 and 3

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

San Francisco, Adelaide, Cape Town, and Sydney all experience a Mediterranean climate, characterized by warm, dry summers and mild, wet winters. These locations are situated in the mid-latitude zones on the western or southern coasts of their respective continents.

Multiple choice

Which one of the following is the correct statement ?

Kalahari is a desert because it

  1. lies in the tropics

  2. is on the leeward side of a mountain

  3. underlies a high pressure cell

  4. receives only land winds

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Kalahari Desert is primarily caused by its location under a semi-permanent subtropical high pressure cell (the subtropical high), which causes descending air, warming, and a lack of cloud formation and precipitation.

Multiple choice

Consider the following statements :

  1. Humboldt gave the first scientific description of the relation of altitude, air temperature, vegetation and agriculture in tropical mountains.
  2. Ritter developed the concept that continental climates are colder in winter and warmer in summer than the climates at places near the oceans at the same latitude. Which of the statements given above is/are correct?

  1. 1 only

  2. 2 only

  3. Both 1 and 2

  4. Neither 1 nor 2

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Alexander von Humboldt is widely recognized for his work on plant geography and the vertical distribution of vegetation in tropical mountains. Carl Ritter is known for his comparative geography, but the specific description of continental versus maritime climate influences is more generally attributed to his broader geographic synthesis and comparative methods.

Multiple choice

Assertion (A) : Cyclones over Bay of Bengal are characterized by clockwise circulation.

Reason (R) : Their circulation is governed by pressure gradient and coriolis force.

  1. Both A and R are individually true and R is the correct explanation of A

  2. Both A and R are individually true but R is NOT the correct explanation of A

  3. A is true but R is false

  4. A is false but R is true

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cyclones in the Northern Hemisphere (including the Bay of Bengal) rotate counter-clockwise due to the Coriolis effect. The assertion is false.

Multiple choice

Assertion (A) : Cirrus clouds primarily contain ice particles.

Reason (R) : Cirrus clouds occur at very light altitudes.

  1. Both A and R are individually true and R is the correct explanation of A

  2. Both A and R are individually true but R is NOT the correct explanation of A

  3. A is true but R is false

  4. A is false but R is true

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Cirrus clouds form at high altitudes where temperatures are very low, causing water vapor to freeze into ice crystals. This explains why they are composed of ice particles.
