Climate, Weather, and Geography

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.

B Correct answer
Explanation

Normal El Nino forms in Southeastern Pacific, whereas El Nino Modoki forms in Central Pacific and causes greater number of hurricanes.

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

The climatic conditions which are given in the table denote the climatic condition of China.

Multiple choice

Consider the following statements about ‘Roaring Forties’:

  1. They blow uninterrupted in northern and southern hemispheres.
  2. They blow with great strength and consistency.
  3. Their direction is generally from north-west to east in the southern hemisphere.
  4. Overcast skies, rain and raw weather are generally associated with them.

Which of these statements are correct?

  1. 1, 2 and 3

  2. 2, 3 and 4

  3. 1, 3 and 4

  4. 1, 2 and 4
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The westerlies in the southern hemisphere are called roaring forties.

Multiple choice

An area which has not been glaciated may show

  1. hanging valleys

  2. corries & pyramidal peaks

  3. drumlins

  4. V-shaped valleys

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

Hanging valleys, corries, pyramidal peaks, and drumlins are all landforms created by glacial erosion or deposition. V-shaped valleys are characteristic of river erosion in non-glaciated mountainous regions.

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

  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.
