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

Ground water is an agent of erosion, transportation and deposition. Regarding ground water, pick correct statements.
(1) Water filling up joints and pores-spaces is ground water.
(2) Groundwater plays an important role in weathering and mass movement.
(3) It re-enters hydrological cycle as springs.
(4) Amount of water available as ground water depends upon climate, season and nature of rocks.

  1. 1 and 4

  2. 2 and 3

  3. 3 and 4

  4. All of these

D Correct answer
Explanation

Groundwater is water that occupies the pores and joints in rocks. It is a key agent in weathering, mass movement, and the hydrological cycle, and its availability is heavily dependent on local environmental factors.

Regarding mass movement, choose the correct statements.
(1) Movement of weathered material down slope.
(2) Gravitational force of Earth is the reason for mass movement with multiple triggers.
(3) It is dependent upon gradient of slope, weight of weathered debris and presence of any trigger (lubricating agent or vibration).
(4) There are 3 types of mass movement.

  1. 1 and 4

  2. 1, 2 and 3

  3. 1 and 3

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Mass movement is the downslope movement of material driven by gravity. It is influenced by slope gradient, material weight, and triggers like water or vibrations. There are many types of mass movement (e.g., creep, slide, flow, fall).

Fluvial erosion is one of the most important exogenetic processes. On what factors does it depend?
(1) Channel gradient  (2) Volume of water
(3) Velocity of flow   (4) Water discharge   (5) Sediment load

  1. 1, 2 and 3

  2. 2, 4 and 5

  3. 1, 3 and 5

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

Fluvial erosion is driven by the energy of the water, which is a function of channel gradient, volume, velocity, discharge, and the sediment load it carries to abrade the channel.

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

Which of the following is/are not erosional land forms?
(1) Cliff
(2) Caves
(3) Wave-cut platform

(4) Beaches

  1. 1 and 2

  2. 1 and 3

  3. All of above

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cliffs, caves, and wave-cut platforms are erosional landforms created by wave action. Beaches are depositional landforms formed by the accumulation of sand and shingle.

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.

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

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.
