Multiple choice landforms on earth and external processes general physical geography general knowledge

If a small raindrop falls through air ______.

  1. its velocity goes on increasing

  2. its velocity goes on decreasing

  3. its velocity goes on increasing for some time and then becomes constant

  4. it falls with constant speed for some time and then its velocity increases
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

As a raindrop falls, gravity accelerates it, but air resistance increases with velocity. Eventually, the drag force equals the gravitational force, and the raindrop reaches a constant terminal velocity.

Which one of the following planetary wind is known to blow steadily in the same direction and in the constant course? 

  1. Trade winds

  2. Westerlies

  3. Equatorial Easterlies

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

Polar Easterlies are planetary winds that blow from the polar high-pressure belts toward the subpolar low-pressure belts. They are known for their relative steadiness compared to other wind systems.

Logically, what does a continually rising air pressure indicate? 

  1. Advent of unsettled and cloudy weather

  2. Advent of a cyclone

  3. Fine and settled weather

  4. Fine and unsettled weather
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A continually rising air pressure indicates that a high-pressure system is moving in, which is typically associated with stable, clear, and fine weather. Conversely, falling pressure generally signifies the approach of storms or unsettled conditions.

The windward slopes of coastal mountains which are at right angles to wind blowing from the sea are wetter than the leeward slopes. This is because _______.

  1. they are nearer the sea

  2. the winds have to rise to cross them

  3. descending winds are warm

  4. the sea is warmer than the land
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Moisture-laden winds blowing from the sea are forced to rise when they encounter coastal mountains (orographic lifting). As the air rises, it cools adiabatically, leading to condensation and heavy precipitation on the windward slopes.

What is the name of the winds that blow from the subtropical high pressure belt towards the subpolar low pressure belt?

  1. Easterlies

  2. Trade winds

  3. Westerlies

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

The Westerlies are the prevailing winds in the middle latitudes between 30 and 60 degrees, blowing from the subtropical high-pressure belts toward the subpolar low-pressure belts.

Which of the following factors is primarily responsible for the planetary wind belts?

  1. The Earth's rotation

  2. Alternate areas of low and high pressure

  3. Differential rates of heating of water and land surfaces

  4. The tilt of Earth's axis
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Planetary wind belts are primarily driven by the global distribution of high and low pressure, which is caused by differential heating of the Earth's surface and the resulting atmospheric circulation cells.

A Mediterranean climate is characterised by very dry summers because ______.

  1. the relative humidity is low

  2. the skies are cloudless

  3. the trade winds blow from the land to the sea

  4. there are no off-shore winds
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mediterranean climates experience dry summers because the subtropical high-pressure belts shift poleward, causing trade winds to blow from land to sea. Since these winds originate over land, they are dry and do not bring precipitation to the coastal regions.

Choose the correct statement:
1. Purga is snow laden cold wind in Russian Tundra.
2. Bise is an extremely cold wind in France.
3. Yamo is a warm and dry wind in Japan.
4. Santa Ana is a warm and dry wind in Argentina.

  1. 1 and 2

  2. 1,2 and 4

  3. 1,2 and 3

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

Purga is a cold wind in the Russian Tundra, Bise is a cold wind in France, and Yamo is a warm, dry wind in Japan. Santa Ana is a warm, dry wind in California, USA, not Argentina.

The two areas having continental glaciers are _________.

  1. Glacier National Park/Waterton Lakes National Park

  2. Antarctica/Greenland

  3. Norway/Sweden

  4. Canada/Siberia
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Continental glaciers, or ice sheets, are massive glaciers that cover vast areas of land. Antarctica and Greenland are the only two regions on Earth that currently host true continental ice sheets.
