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.

Climate, Weather, and Geography Questions

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
B Correct answer
Explanation

Cirrus clouds are high-altitude clouds characterized by thin, wispy strands. They typically form above 20,000 feet and are composed of ice crystals.

Multiple choice

What is a tornado?

  1. It is heavy snowfall

  2. It is a violent storm

  3. It is cool breeze

  4. It is a violent storm accompanied by heavy rain

D Correct answer
Multiple choice

Which one of the following has the highest wind-velocity?

  1. Hurricane

  2. Tornado

  3. Typhoon

  4. Thunderstorm
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tornadoes have the highest wind velocities among the options, with winds that can exceed 300 mph (480 km/h) in the most extreme cases. Hurricanes and typhoons (which are the same phenomenon, just named differently based on location) typically have maximum sustained winds around 150-200 mph. Thunderstorms, while severe, generally have lower peak wind speeds than tornadoes.

Multiple choice

Cirrus clouds are

  1. low clouds

  2. very low clouds

  3. high clouds

  4. medium height clouds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cirrus clouds are high-altitude clouds that form above 20,000 feet (6,000 meters). They are composed of ice crystals and appear as thin, wispy, feathery clouds. This distinguishes them from low clouds (stratus, cumulus under 6,500 feet), medium clouds (altostratus, altocumulus 6,500-20,000 feet), and very low clouds (fog, mist).

Multiple choice

Which of the following has the highest wind velocity?

  1. Typhoon

  2. Hurricane

  3. Cyclone

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

Tornadoes generate the most extreme wind speeds, with EF5 tornadoes exceeding 300 mph. While hurricanes and typhoons are larger systems with higher total energy, their sustained winds typically max out around 180-190 mph.

Multiple choice

Which of the following statements is false?

(a) The falling of drops of water from the clouds is called precipitation. (b) The clouds rise higher in the atmosphere because they are warmer and lighter than the surrounding air. (c) Ocean water is very useful for use in agriculture, animal and human use. (d) Earth has water in solid, liquid and gaseous state.

  1. Both a and b

  2. Only c

  3. Only d

  4. Both b and d

  5. Only a
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Ocean water is saline, i.e., it contains a large amount of salt in it. Therefore, it is not fit for use in agriculture or animal and human use. This is the correct option, as the statement is false.

Multiple choice

Which of the following is found along 30 degrees north and 30 degrees south?

  1. High pressure areas known as polar highs

  2. High pressure areas known as equatorial highs

  3. High pressure areas known as sub-tropical highs

  4. Low pressure areas known as sub-polar lows

  5. Low pressure areas known as sub-tropical lows
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Along 30o N and 30o S, are found the high-pressure areas known as the sub-tropical highs. This is the correct answer.
