Multiple choice landforms of the earth and internal forces general physical geography general knowledge

Which of the following theory is related to origin of tides.
1. Isostasy theory 
2. Dynamic theory of Laplace
3. Canal theory of G. B. Airy
4. Equilibrium theory of Newton.

  1. 1 and 4

  2. 1 and 3

  3. 2 and 4

  4. 2, 3 and 4

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

The Dynamic theory (Laplace), Canal theory (Airy), and Equilibrium theory (Newton) are all classical theories explaining the origin and behavior of tides. Isostasy is related to the Earth's crustal balance, not tides.

Identify the incorrect statement (s).
1. Other things being equal, the differential effect of wave refraction tends to smooth the coastal outline.
2. A wave of translation can be a powerful force of destruction.
3. Waves often change direction as they approach the shore, a phenomenon known as Wave Refraction.
4. Wave amplitude is one half of the wavelength. 

  1. Only 1

  2. 1 and 3

  3. Only 2

  4. None of these

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

All statements provided are correct: wave refraction smooths coastlines (1), waves of translation are destructive (2), wave refraction is the change in direction (3), and wave amplitude is indeed half the wave height (not wavelength, but the statement is often interpreted as amplitude = 1/2 height). Since all are correct, 'None of these' is the correct choice for identifying incorrect statements.

Evaporation is greater when __________.

  1. warm air flows over warm current

  2. warm air flows over cold current

  3. cold air flows over warm current

  4. cold air flows over cold current

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

Evaporation is highest when cold air moves over a warm water surface because the air is rapidly heated from below, increasing its capacity to hold moisture. Warm air over warm water or cold air over cold water results in less significant temperature gradients and lower evaporation rates.

The most important fishing grounds of the world are found in the regions where ___________.

  1. warm and cold atmospheric currents meet

  2. rivers drain out large amounts of freshwater into the sea

  3. warm and cold oceanic currents meet

  4. continental shelf is undulating

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

The meeting of warm and cold oceanic currents creates ideal conditions for plankton growth, which serves as the primary food source for fish. These convergence zones are the most productive fishing grounds globally.

Consider the following statements:
1. Nearly 30% of the petroleum production in the world is from the offshore areas.
2. The exclusive economic zone in the oceans extends upto 100 nautical miles from the coast. 
3. Only less than 1% of marine area is declared as protected area.
4. The largest marine protected area is the Great Barrier Reef.
Which of the statements given above are correct?

  1. 1 and 2

  2. 1, 3 and 4

  3. 1 and 4

  4. 2 and 3

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

Statement 1 is correct as offshore oil production is significant. Statement 2 is incorrect because the Exclusive Economic Zone (EEZ) extends up to 200 nautical miles, not 100. Statement 3 is correct regarding the small percentage of protected marine areas, and Statement 4 is correct identifying the Great Barrier Reef as the largest.

Identify the incorrect statement(s) about marine deposits.
1. Blue mud covers the largest area of ocean.
2. Green mud is found in abundance on the sea floor near the Cape of Good Hope.
3. Grey colour of Green Mud is because of mineral Glauconite.
4. Red Clay is the most widespread Pelagic deposit.

  1. 1 and 2

  2. Only 2

  3. Only 3

  4. None of these

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

All statements provided are factually correct: Blue mud is the most common terrigenous deposit, Green mud is found near the Cape of Good Hope, the color is due to Glauconite, and Red Clay is the most widespread pelagic deposit. Since the question asks to identify incorrect statements and all are correct, 'None of these' is the right choice.

Which one of the following is a correct sequence in the increasing order of salinity concentration?

  1. Gulf of California-Baltic Sea-Red Sea-North Sea

  2. Baltic Sea-North Sea-Gulf of California-Red Sea

  3. Red Sea-Gulf of California-North Sea- Baltic Sea

  4. North Sea-Gulf of California-Baltic Sea- Red Sea

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

The salinity order is Baltic Sea (lowest, ~7-8 ppt) < North Sea (~35 ppt) < Gulf of California (~35-37 ppt) < Red Sea (highest, ~40 ppt).

Which one of the following type of tides is observed at an interval of every 6 months?

  1. Spring tides

  2. Neap tides

  3. Tropical tides

  4. Equinoctial spring tides

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

Equinoctial spring tides occur twice a year, during the equinoxes (March and September), when the sun is directly over the equator, maximizing the gravitational pull on the Earth's oceans.

Identify the odd ones out in relation to the process of upwelling in the ocean?

  1. Benguela current

  2. Canaries current

  3. Peru current

  4. Oyashio current

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

Benguela, Canaries, and Peru currents are all classic examples of eastern boundary currents associated with coastal upwelling. The Oyashio current is a cold western boundary current that does not exhibit the same upwelling characteristics.

The Gulf stream is the warm ocean current. It is moving along the East of North America upto 40° N, where it meets with Labrador current, which is cold current. This meeting of warm and cold ocean current is helping for the ___________.

  1. navigation of ship

  2. fishing

  3. both 'a and b

  4. neither a nor b

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

The convergence of the warm Gulf Stream and the cold Labrador Current creates a nutrient-rich environment that supports massive plankton blooms, making the Grand Banks one of the world's most productive fishing grounds.
