The interval between two high tides is approximately _________.

  1. 4 h 12 m

  2. 6 h 13 m

  3. 12 h 26 m

  4. 24 h 52 m

C Correct answer
Explanation

The Earth rotates once in 24 hours, but the moon also orbits the Earth in the same direction. This makes the lunar day about 24 hours and 52 minutes long, resulting in high tides occurring roughly every 12 hours and 26 minutes.

On the planet Earth, most of the fresh water exists as ice caps and glaciers. Out of the remaining fresh water, the largest proportion _____________.

  1. is found in atmosphere as moisture and clouds

  2. is found in freshwater lakes and rivers

  3. exists as groundwater

  4. exists as soil moisture

C Correct answer
Explanation

After ice caps and glaciers, the largest reservoir of fresh water on Earth is groundwater, which accounts for a significant portion of the remaining liquid fresh water.

Extensive coral formations develop between 30°N and 30°S especially on the sides of the landmasses.

  1. Eastern

  2. Western

  3. Northern

  4. Southern

A Correct answer
Explanation

Coral reefs are more extensive on the eastern sides of continents in tropical regions because the western sides of ocean basins have cold currents that inhibit coral growth, while the eastern sides have warm currents.

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.
